The huge New Madrid earthquakes of 1811-1812 created Reelfoot Lake and temporarily backed up the Mississippi River, but they also shook hills in the surrounding landscape until they spread and cracked. This video shows was the process looks like and uses LiDAR imagery to reveal what the shaken ridges really look like.
Your sandbox model was ingenious, it really conveyed the idea of how these landforms develop.
My family lived there from around the mid 1800's. I have heard stories from my mom that she didn't have power or running water until she was around 14. it was all outhouses and oil lamps. My grandfather bought some land and started farming with a mule and over time ended up owning and farming about 10k acres in New Madrid. He use to take me hunting and fishing and even taught me how to drive at 10years old. I love New Madrid, the people are so nice and I will never forget the memories.
Great. Not really related to the vid and no one asked but nice.
Thank you for that commentary. I’ll look back into time. 😊
You might be interested in the video I recommended in my comment.

Thank you for sharing. I live in Dyer County, with family in Obion and Lake Counties. I love Reelfoot Lake and (found a great video )with "History highlights" and "with a reading of letters written in the era of the Earthquake and about the experience in the area", (see Link below)
A couple of years ago I did a search for the center point of the actual fault line, and was ever so surprised to find it revealed the town I live in: Newbern, TN, (right where your arrow is pointed), I was stunned.
I don't recall the site, but anyone can Search it, it gave the Longitude and Latitude.
I grew up in NW Tennessee, after college, I moved to Nevada, lived there for 17 years, traveling every other week or so with my job. It was always wonderful to go home each time. I was there for 2 intense quakes, one a shaker and one a roller. (There's always footage in the Casinos, you could see the movements).
🔺 For those interested, I highly recommend the following video, here on RUclips:

I was a truck driver and I was in Chico, CA I think it was 2007 or 2008. I had just opened my trailer doors and backed in and bumped the warehouse dock. I waited for a good while (you truckers know what I'm talking about) and all of a sudden I felt the loaders driving the forklift into the trailer and they were rough as hell - the trailer shook side to side - sometimes loaders are really aggressive and then it stopped so I got out to tell em to be gentle with me just to joke - I looked in between there and the dock door was still closed and I could see inside the trailer, no pallet was in there yet and I said damn! WTF? I crawled back in the tractor and turned on the radio and found a channel - "Folks - WE have just had an EARTHQUAKE!! Turned out it was an 5.7 near Chico Hills. Now I'm from Georgia and we had an earthquake once that woke me up but I'd never experienced one in the earthquake capital of world southern Cal, and I was pissed off that my first CA earthquake, I thought it was a forklift driver. I'm still pissed off
Ow.
My first earthquake was near a construction site. I thought a dump truck had tipped over.
I missed another earthquake because I was getting up and turning around when the single jolt hit.
I live in Hornbeak, TN, which is in Obion County. People would be surprised to know that we have small earthquakes quite often. I live 11 miles from Reelfoot Lake (the lake that was formed from the earthquakes of 1811-1812). We have so many people, including tourists, that if another major quake happened, it would be devastating. I think we would undergo a complete geological change. A part of me wishes I could have seen the earthquake that formed Reelfoot Lake. How amazing would it have been to see the Mississippi River run backwards???
Apparently it's a matter of WHEN and not IF it happens again. Population growth is always a major concern with natural disasters. Fla and Hurricanes, Ca and Earthquakes. It's endless.
@@karlheinzvonkroemann2217Yes, it's definitely when, not if. However if you look at the historical cycle rate(via numerous studies by USGS), the reoccurrance probability for that area(for a major earthquake) suggests its at least quite a while before happening. However in researching the same material, one learns the Wabash fault area is WAY overdue for similar events.
I grew up in Hornbeak and still live in Obion County, TN. I remember being in fear of an earthquake in my youth. Grew up going to Reelfoot lake parks. And school field trips to the museum every year. We’ve been told we when were over due for a major earthquake that would put an earthquake in Cali to shame. It’s definitely an active fault line!
The only natural lake in the South
Earthquakes are bad but you dodged a bullet when that tornado hit in 2021 by just a few miles 😅
I believe it was about 1975 and my family was living in Shelby County near Memphis. I was about 13 and I remember I was on the toilet when I heard this weird noise very low. I can’t even say it was a sound and it really caught my attention. About a minute later my house started shaking. On the wall in front of me we had a large mirror, approximately 3x5 if I remember correctly. Well it started jiggling kinda like a jello surface. I jumped off the toilet and put my hands on the mirror to stop it doing its craziness. There I stand, holding a mirror with my pants around my ankles. All I could think was “please G*d don’t let this mirror shatter”. I just knew if it shattered it was going to cut my “down there” off. The earthquake scared me more than any tornado ever did.
Now I live in St. Mary’s County in MD. About 15 years ago we had an earthquake, which is unheard of here since the geology is so old and relaxed. Unfortunately I missed feeling this earthquake cause my son had missed his school bus and I was driving him to school.
If you made it this far I hope you have a great day and a wonderful life.
I must admit I felt an earthquake under the same circumstances a few years back...
I remember that day!!
My ex-mother-in-law was in Shelby county TN .In 1975.And her fat ass 🐘fell down lot. May have caused your house to Trimble. Sorry about that
Well there Kaptain. I liked your little story but I’m old and lived in Southern California my whole life and have forgotten more Earthquakes than I can remember. There have been a couple of doozies that really busted up stuff. Northridge killed people and broke freeways. Whittier almost busted the Sewerage Systems. (I worked for the LA Co. Sanitation Districts.) Once when I was living high in the Mountain Range south of LA we were hit with the most powerful thing I’d ever experienced. It lifted the whole house and slammed it back down so hard my teeth rattled. Now that was exciting. We get them every so often. Usually in 4 - 5 magnitude. Those aren’t too bad. It’s the 6.5 - 7 that will knock you to the ground. Thanks again. Hermit
We felt that in East TN! Our dog hunched chest down on the front porch and peed all over herself! She had never done that before! A couple hours later we were told of the earthquake.
Thanks for sharing. The eye witness accounts of this earthquake, were outrageous. I can’t remember where I read about it, but there was a group of men camping alongside the river, maybe working for a barge company at the time. They talk about deafening gas explosions everywhere, coming up from under the river and the entire flood plain. Massive amounts of dead trees being thrust up from the river bed. After longer than five minutes of shaking, they were running for their lives as they could no longer tell what was river and what was not river. The entire landscape was altered in minutes. Water everywhere bubbling up from the ground, and large chunks of Earth sinking under the water. Sounded like hell on Earth. Like nothing we’ve ever seen since cameras were invented.
Never under estimate the power of nature. Thanks for sharing.
LOL. "Sides move out, top moves down..." describes many people as they age... ❤😂🎉
Geology proves it is the natural way of things!
Welllllll,GRAVITY!
Excellent presentation. You even provided a working model (nice touch). No annoying background music, just facts and observations. I was actually invested the entire time.
Fascinating stuff - LIDAR must be a godsend for geologists, like X-ray was for doctors.
Yep, nothing is the same now, at least in forested areas! I try to remember what work was like pre-lidar, but it's getting difficult to do so...
Retired after having created several geologic maps while lidar point clouds were becoming available in my area(s). I learned how to process them sometime in the middle of that part of my career and quickly realized everything I had done before were incorrect in detail. Assuming my field analysis was correct the exact mapped locations were just not that good before lidar.
I hear you...I have only had about 1/2 of 7.5' quad without high res lidar, but it was a totally different mapping experience. Some of the old Valley and Ridge Virginia stuff came out well, though, presumably due to reduced vegetative cover and the strong rock strength control over topography. I wrote the link below back in 2019 about a '65 map done in an area that now has 1-meter lidar. They actually did a remarkable job!

At 3:35 The Geologist talks about the river bend at New Madrid. It's a horseshoe bend. It is the same type of river bend found at Evansville, Indiana on the Ohio River which is situated on the Wabash Valley Fault Line.
I’m in SEMO. LiDAR imaging is an amazing tool. Cool to see it used here.
It's a game changer for all aspects of geology. I almost can't remember what it was like to work without it.
♥♥♥ GIS Geek here. This is why I love LiDAR so much. In the hands of well spoken analysts (like you) complex mechanisms can be clearly shown. THANKS!
Thanks! I have used the stuff daily (weekends included!) for years now. What did I do before? Just put up a vid about Carolina Bays...I'm not in the impact origin camp, but some of the lidar showing dunes, etc., and their interaction with bays is cool.
@@TheGeoModelsIndeed. I'm "on the fence" as to the impact idea - I've used the "Carolina Bays" LIDAR interval data to investigate the dune fields here in Haskell County Texas. Can't find much literature describing them, yet everything I can tell indicates that it is a major feature that feeds our local aquifer as the dune areas have NO drainage. Our property will absorb a four inch per hour rainfall and be dry in an hour or so.
@@jrkorman I'll have to check out Haskell County. The Llano Estacado has about the most and best "bays" out there, though they are called playa lakes in the region. I would tell you they and bays are the same, but I bet others wouldn't! Texas has all kinds of cool stuff to see.
@@TheGeoModelsAn interesting observation - the playas at and east of Lubbock are indeed playas. They are roughly circular with flat rims. However, look at those to the west of Lubbock, especially Bailey county, TX and Lea County in New Mexico. Totally different shape and rim structure.
The dunes here in western Haskell County appear to be a result of sand blown out of the Double Mountain Fork Brazos River bed. In several locations the patterns match how south westerly winds would have blown that sand. The dune structure ends rather sharply just to the east of Rule, Rochester, and Knox City.
@@jrkorman very interesting. I was cruising around Bailey County earlier. With a big hillshade exaggeration, the Lubbock guys have a bit of a raised southeast rim.
I’m in the Missouri boot heel and it’s on my mind several times a week especially when you get small quakes
I woke up this morning after waking from dreaming of this horrible earthquake that occured here where I live & the house I am at. So dreadful & scary ! Slow motion as allowing me to see it very vividly. It wasn't as though there was shaking to it, rather, the earth was rising & lowering just like waves of the Sea. The home here is large, it was causing the house to break & burst apart, the counter cabinets were seperating & raising off floor at each end about 3 ft, as the house riased & lowered - frightening !!! I told my sister, we got to get out of here ! Woke up.
I live in Southeast Indiana near the New Madrid Faultline.
Fast and pray and ask the Almighty what should y'all do
I've had many dreams of our world being completely destroyed, and I prayed for more understanding about these dreams and the spirit of God said it's a star. A star is going to hit earth and completely recycle the whole planet, maybe two big ones back to back, then turns into Nine small ones that hit again like a bounce back to earth.
You can still see the damage from the New Madrid quake at Pulltite Spring on the Current River. The top of the bluff broke off, a boulder the size of a house came down and is mostly submerged in the spring. You can still see trapped trees under the boulder in the water, and remains of the scar it made coming down.
Now I'll have to check that out. Sometimes you can see tracks left by rolling boulders in lidar imagery back east in the Appalachians. Wonder if this one is visible.
Seriously? Live up the Rd from there, Jadwin.
@@Idrinklight44 True stories. Would have been a crazy event to witness live
@@Idrinklight44 Seriously. If you are standing at the spring and look up, you will see the missing piece of the bluff, on the right. If you look down into the spring you will see the boulder. If you look closely under the boulder you will still see the trees it took out coming down. The trees are still preserved there because of the low temperature and low oxygen water.
My Mom was an insurance adjuster for Kerr McGee for many years, although she was a paper-pusher she had a lot of interest in geology, which I guess is what sparked my interest in it. Anyway, we live in Oklahoma, where it is usually dull and boring, earthquake-wise--until 2011 that is. I happened to be in the ER, brought by my Mom, and we're waiting there to see the doctor when the room starting rolling around. My hospital bed starts skating across the floor, LOL. I looked at Mom and she looked at me, and we both yelled "Earthquake!". She told me that since living in California (UC San Diego, then meeting/marrying my Dad), this earthquake was stronger than anything she experienced living there. That's how we got on the subject of New Madrid--LOL, she says it's kind of ironic that they moved away from California never expecting to have to deal with earthquakes again, then realizing they moved closer to one of the most potentially destructive faults in America. Thank you, I love the new technology that lets us view our world underfoot.
Thanks! Everything looks interesting with lidar. For Oklahoma folks the Wichita Mountains are wild to look at. The fracturing in the granite is really interesting. I'd love to get out there and walk around some. I drove across much of the state on a storm chasing trip last year (of all things) and thought the Wichitas looked awesome...particularly with the storm that put a tornado onto Loco and Comanche behind them. I'll have to get out there on foot one of these days.
I lived in California for a small chunk of my childhood, I live in Arkansas and have for years now, but I've felt more earthquakes here than I did on the west coast 😂 weird isn't it
@@TheGeoModels I bet you'd enjoy it. If you get the time, come check out the Arbuckle Mountains as well. I used to live a few miles outside of Sulphur, near some abandoned asphalt mines that filled with spring water and are now very deep but beautiful little lakes. The geology here is so jam-packed with cool stuff that the university sends their geology classes down here on field trips. We just got hit by a tornado Saturday though, so give it a few weeks for us to get the storm damage cleaned up and the highways back open. After that--have a great trip!
I'm just glad you stayed at a Holiday Inn Express
I hear you. I like their pancake machine!
Fascinating! Thank you. Glad RUclips showed me your channel.
Thanks! My videos are set up a bit differently but I promise I've got something to say and show!
You know you had a massive earthquake when it was strong enough to reverse the flow of the Mississippi River!
You're a man of your word! I find this series of earthquakes one of the most fascinating in recent history. You could do a video about some aspect of it every week and I'd never get bored, but then we'd miss out on all the other topics you cover! Hahah! Cheers!
I hear you. Shaking topography for this one gave me a nice lateral spread video idea, so thanks for pointing me that way!
I'm about 48 minutes from the Fault towards Kennett, Mo area. We were wondering what a quake would do to the landscape around that area when we see a reoccurrence
Looks like Southern Illinois even though it's supposedly a little bit out of the damage range but I don't think it will be this time at all
excellent model! I learned something today from that!
I remember, as a child, riding with my family through Northern Arkansas and watching out the window. I noticed several fields of light colored soil with large round areas of dark soil, I guess from liquefaction and upwelling of darker soil. I had no clue as to what caused them. The New Madrid earthquake was not discussed or taught in school because it was bad for business, I guess.
I grew up in the pine forests of Georgia and man oh man the Lidar is breathtaking. So many paleo structures.
Subscribed and looking forward to more succinct videos like this.
Appreciate it! Were you here for the lidar or the earthquake stuff too? I love lidar to death but it seems to bog down the algorithm if you mix and match your subjects too much
@@TheGeoModels Geology + Lidar is pretty much an instant entry to my playlist. Love learning new things about landscapes I've inhabited and am familiar with. Really like this video a lot. I'm a rambler and appreciate people who aren't. :D
@@vhhawk Sounds like a plan. You see the video linked below? It did not enjoy popularity but the lidar is cool. For the last few years much of day-to-day has been identifying features in lidar then actually hiking to them to see what's causing the slide, etc.
ruclips.net/video/hBvTcSdO-CI/видео.html
Look at the hills in LaSalle Parish Louisiana. Some of our steep hills to the east on the edge of the Mississippi flood plain have huge slides and cracks. I found large out of place sand blows with chunks of coal in them in NW Louisiana too.
I live in the Rockies, & was in abt 5th-6th grade when I learned abt the 1811-1812 earthquakes from the kids' book Haunted Island by Joan Lowery Nixon (the blue cover one, if you look it up). It was one of my favorite books. I still have it, somewhere.
This was a totally blooming fascinating video. I've never see lidar used in this context.
Thanks! There's more on the channel. Should have another few out soon enough.
It would have been interesting to see some of these features on the ground.
Davy Crockett noted eery sunken lakes with trees sticking out of them during his overland travels in Tennessee, which of course were sunken areas created from the earthquake. It has been reported that this earthquake made church bells ring in Boston!! Great video, thanks!!
Now that's cool. I'll have to read up on that. Davy's childhood home on the Nolichucky got messed up by a huge flood, which likely produced landslides up in the mountains. I'd love to track some of those down, but it's likely impossible.
Great video!
It's a fascinating corner of the world, for sure
IDNR in IL has a hillshade LIDAR tool. Its made my engineering work a lot easier and useful to confirm features in survey and give more detail in my models.
I have gotten a real kick out of the Hicks Dome area in southernmost Illinois. I admit I never much thought about there being topography and outcrops down there. Some of the joints and fractures in the cliff lines on the north flank of the dome are about as good as you can see anywhere in the US with lidar.
Most people don't realize or know how many earthquake fault lines , that they live close to. They be surprised.
Indeed! I think about this all the time!
Cool video. Thanks!
Glad you liked it! Trying to get something else out here soon.
could you comment more on how the ridge summits formed right next to very flat topography. thanks
Well done, thank you!
Very glad you enjoyed it! LiDAR is great stuff for seeing the world!
Great stuff!! So these Lidar images in google earth are a feature or you incorporated the lidar image panels via KML or KMZ files from other maps? Thanks inadvance!
They are kmz panels. I export JPEGs from ArcGIS and make the kmz's from them. Data was from USGS National Map download platform. I prefer to handle a lot of imagery this way because Arc is always a bit clumsy. For modern landslide work and structural geology, being able to flip back and forth between different years of Google Earth imagery and the lidar is key!
@@TheGeoModels Copy that!! Thank you very much!!
👏🏻👏🏻👏🏻Ty for this!
🦋
Very interesting. Thank you.
Thanks for watching!
Really nice models here. Born in Sikeston and spent a lot of years in Poplar Bluff and Kennett. Always aware of the interesting structures and land changes from the New Madrid quakes and seismic system. Have you done any model on the sand blows or how buried trees have floated up to the surface from that activity? Wonder how many neighborhoods are build over these deep soft sediment layers and are in danger from the next event.? Well done.
Haven't tried a sand blow...not even sure how I'd do it! Definitely sounds like a good challenge. The video linked below has a buoyant object floating out of the liquefied sand (after the bus sinks...).
ruclips.net/video/cSaatSdS4Sk/видео.html
I've played around a bit with a home-made stream-table model using very fine sand that I can tilt and shake. Its interesting how saturated shaken fine-grained sediment behaves.
@@andywomack3414 I got an older video on here where I hammer a metal bucket full of wet sand. It's crude but interesting...I added the element of a buried buoyant item, which floats with the liquefaction. Some other Mr. Wizard-type of channel borrowed that down the road, which I rather liked! Using the dry media with the frictionally weak microbeads does a nice job with the scarps. I guess much of the video was sort of a lidar-interpretation kind of thing, though the model scarps are produced by the same sort of deformation as the real thing (just without fluid pressure reducing shear strength).
I clicked on this because I live nearby in Blytheville, AR, and we experience LITTLE quakes all the time. Rarely do we ever feel them. But my husband just texted me a few min ago to let me know just felt an earthquake. It was a 3.6 in Etowah, while he was at work at his desk near Dell.
Very interesting, has a lidar study been done in northern Illinois near the Lasalle anticline?
Not sure of a specific one...I'll try to give it a look on National Map and might post up a screen capture. Sounds interesting...
Very interesting; the use of LIDAR in particular. I wonder whether you have ever taken a look at the LIDAR imagery as used by Antonio Zamora regarding the hypothesis concerning the Carolina Bays. He makes some compelling arguments regarding their formation. A number of his videos are on YT; even a short look will likely raise some interesting questions. Cheers.
Yes, I have looked at them and was planning to do a vid. I am of the non-impact origin camp, but certainly the evolution of the one-time lakes and what the south carolina coastal plain used to look like is fascinating in and of itself. Hope to get one put together shortly!
Thanks for the response. I'll stay tuned in the mean time and look forward to checking out some of your other geomorphology models. Cheers.
@@TheGeoModels
I'd like to hear your take on Crowley's Ridge in east -central Arkansas. It runs north/south in the delta country and is a very rare geologic formation that kind of defies explanation. The ridge runs from just south of Forrest City and north nearly to Jonesboro. It is around 150 miles long, and rises to a height of over 500' above the Mississippi alluvial plain, and I haven't found anything definitive on its origin. There is a page on Wikipedia as well as several other articles and webpages on the Ridge.
Thanks for your efforts! I enjoyed. this one and am subscribed now.
Now that's an interesting feature...I have looked at before with regard to where the St Francis River cuts into its east side down around Forrest City--it does interesting things to the streams on top of the ridge that flow back to Crow Creek in the center of the ridge. Never been to it in person though...It's definitely an erosional remnant that hasn't been beveled off by the rivers yet, but the topography makes it look like it has some "structure" and might indeed reflect some slow ground surface movement. It must look interesting in person with how it rises above the flat lands, for sure.
@@EGlideKid sounds like Low Country South Carolina. There is an area called "High Hills of Santee" that is just like a miniature Crowleys Ridge. You can actually Google it; it has a Wikipedia page. Folks treated it the same way as Crowleys...I'm sure it was only spot to catch a breeze and lose some mosquitoes and cottonmouths! I would say they are geologically similar, too...
can lidar expose the sand blows as well? those were quite extensive down there....
Not sure, but it would be tough because the sand comes out as a liquidy slurry and doesn't pile up well to leave a mound to produce a shadow in the hillshade. If the sand covered some sort of existing gully or something like that, you might see it as an odd looking smooth spot. It's a cool question. I'll see if I can check it out.
Glad I stumbled onto your geology site! I live in Washington State and follow Shawn Wilsey, Myron Cook and Nick Zentner, and we’ll respected western geology educators. As you well know we’ve got some feisty volcanoes and the Cascadia subduction zone menacing us. We’re probably better prepared than you folks in MO, KY and TN, but can we ever be ready for the “big one” or the big blow up?
I don't think anyone, anywhere is ever ready because of the amount of energy released in a large quake, eruption, etc. It's just at a scale beyond anything that is really relatable to humans...
Did you come across this channel through a search or was it suggested?
@@TheGeoModels suggested by the great RUclips algorithm. I first learned of LIDAR after the Oso landslide in 2017 near Arlington, WA State. There have been MANY slides in that area over the ages!
NEAT! I actually fly a drone that takes LiDAR imagery for my work. In grad school, I used existing LiDAR to discover aeolian landforms on the mid-Atlantic coast. (There are Barchan dunes in Delaware, who knew! Among other things, like Carolina Bays... but I digress.) Anyway, the YT algorithm seemingly brought me here on a whim, and this was so cool that I instantly subbed. Thanks for posting this, looking forward to more!
well you can argue with folks on my bays videos that the dunes really are dunes! Most of them in SC are parabolics. I was trying to use Lencois Maranhenses as an analog but that's mostly barchans. Good to know there is some barchan action in the old Coastal Plain
@@TheGeoModels Let me guess: it's a bunch of comments about how they were all created catastrophically. I've tried debating against this viewpoint before to no avail. But I will check it out, thanks for replying!
@@testbenchdude I can see you are not new to this one...
There's like 140 comments on the vid about "what folks won't show you" where the sand dunes are brought up. Toss your two cents in and you are guaranteed to get a bite...I would think, anyway!
@@TheGeoModels I suspected as much. I'm not fishing for "bites" though. I'm a strong proponent of "the truth is both stranger and more fascinating than the fiction." Giving this one a watch now. :)
Do you have any idea what caused the massive scarp near Dallas Texas? The flat land suddenly drops and resumes at the bottom and you can see the "cliff" when you look right or left. If I remember correctly it`s a pretty large drop of nearly 100 feet or maybe more. Been many years since I`ve seen it.
Do you remember exactly where near Dallas? Was it on Interstate 20?
@@shesees432 I don`t remember. I worked there in 1985. It was very difficult to find much about it online and I forgot what it`s named.
@@shesees432 I remember the buildings looked small in the distance and you could see the long line of taillights ahead from the top. The building with the ball on top was on the other side of the city from the drop I believe. But I may be wrong. I had a head injury in 1988 and my memories were messed up.
I live in the Bootheel of Missouri...we've had a few good ones over the years...
Does the picture of 'Fault Line ! ! ! ' somehow explain Reelfoot Lake and the New Madrid zone ?
General trace of the zone of surface deformation that backed up Reelfoot Lake, disturbed the Mississippi River, etc. This vid is more about the landscape disturbance associated with shaking--particularly the sackungen on the river's east side. Aulacogens and late Cenozoic-modern stress regimes are probably best left for another vid! Thanks for watching!
I was raised in new Madrid county. I remember few tremors but we had a glass of water to let us know if there was a tremor by just watching ripples in glass
I lived in Fayette county for 10 yrs. I made lots of money updating old structural steel framed buildings for modern seismic standards due to that fault line.
There are some faint scarps along parts of Crowley's Ridge in Northeastern Arkansas, too. Not as impressive as these, though. This is wild.
Never heard of LiDAR before your videos. Super interesting. Be nice if there was a Google Earth version of LiDAR.
I hear that...the National Map serves streaming lidar at good resolution for much of the country, but you can't see it in 3-D and it's cumbersome to fade to surface imagery. ArcGIS Pro has a good 3D function, but it's cumbersome too (like everything in Arc). I really like to make the Google Earth kmz files with images exported from Arc so it's easy to spin them around and fade out to aerial photography from different years. Hopefully National Map will fire up a 3D viewer someday.
I'm 15 mins west of st.louis...are we at risk? We are on caves which bothers me...
I never realized how much it would bother me hearing it pronounced New Madrid rather than New Madrid... I wonder when that change happened? 20 years ago, I had never heard it pronounced New Madrid, but it seems to be the accepted pronunciation these days.
1811 Tecumseh’s Comet
2024 Tsuchinshan Comet ....not much being talked about the 2024 comet yet but it could get very interesting
2024 will be remembered as the year if great awakenings. Earthquakes
Devil's comet
It would have been helpful if you had shown, discussed and shown the New Madrid Fault location in conjunction to these changes, as well as the intensity zones going out from it. It would also be helpful to hear the historic earthquake evidence / data from the last 200 years for the US.
Sounds look a good idea for another video! Thanks for watching!
I read that there was a column of hundreds of thousands of squirrels leaving the area
If I saw that I would leave too
I’m not a geology guy but I have rocks on my desk so there’s some interest there. After that new years quake I’ve been crazy over earthquakes. RUclips knows what I want.
For real...they know too much sometimes
If I've said it once, I've said it many times. It's not my fault.
I have wondered about the quakes and read up on them. It was horrible for the people there, they had no way of knowing what was happening. And they were all high 7's and low
8's. If New Madrid were to break again, it would be devastating. And will be felt here too, Joliet, Illinois. I have felt a few quakes here they were small, but scary. I keep hoping it would not happen again. But I know that it will happen.
If the area experiences anything like the 1811-1812 events, it will be noteworthy to say the least! We will hope it doesn't come to that in our lifetimes!
@@TheGeoModels that's my hope. Don't know what would be worse, New Madrid or Yellowstone blowing.
Definitely Yellowstone!@@jenniferbeyer6412
I live in Obion County, TN and grew up in Hornbeak. My whole life we’ve been told to be prepared for a major earthquake. This next eclipse in 2024 crosses over the path of the 2017 eclipse to form an X over the New Madrid fault. History shows that eclipses that cross over one another to form an X, an earthquake usually follows.
I will be coming back to this video if we have another earthquake of any note in 2024!
Do you have evidence for that statement?
Do you know the story of Tecumseh? A different take on the earthquake of 1811
Hearsay and no truth to it. Complete bs.
@dforrest4503 do your own research on the eclipses crossing. I’ve done mine. After the earthquakes of 1811-1812 apparently there had been a similar phenomenon prior to
I believe this earthquake actually made the river run backwards?
We have about 5-6 weeks in my estimation before it goes again. Hope I am wrong.
East Tennessee fault line. Tennessee has had over 300 small earthquakes in a year.
I would love to play with a LiDAR map. I’m gonna see if I can find one.
Check out the National Map Viewer that the USGS runs. You should be able to Google for it. You can pick out Hillshade or Stretched Hillshade from the Layers tab and cruise just about all of the US in high resolution. I should probably put a video showing which tabs to select. It's a great resource and very interesting to look at!
Many will now go to the forests, hike the ridgelines and begin to recognize the origins of what they are scrambling over.
I noticed your last name-my mother’s maiden name was Prince. Wonder if we are related?
If they are in the southeast it is possible!
Interesting.
In the world of geology, LiDAR makes everything better!
Is tis what caused "trees to disappear"?
Very possibly...ground movement related to liquefaction/fissure/scarp development looks very strange in "real life," particularly in 1811 when you couldn't watch a video of it happening elsewhere. Old descriptions of landslides are always unusual just because the events themselves are not something you see everyday.
How old are those sedimentary layers, and how well consolidated? I imagine that the sediment of those ridges would be saturated. There must be an element of liquefaction, as evidence by other effects from the 1811-12 quakes. Much water must have been released from those shaking sediments. Could some of the drainage marks on the flanks of the ridges have been formed by that released water?
Not sure about the drainage marks (probably lots of bad conservation over the decades as well), but yes, it's sort of a liquefaction-type response. In the dry models I used, the weak material inside the model ridge loses interparticle friction with shaking, and the stress field resulting from the shape of the ridge controls the failure style. The real ridges are unconsolidated stuff; not sure how old they are, but it's not flat lying rock in the Appalachian Plateau sense by any stretch. Maybe the interiors of the ridges liquefied within the saturated zone? Lots of sand blows around, etc., down in the flats.
@@TheGeoModels The sand I use is dune sand from a dune eroded out of a formation that was deposited as a dune during Mesozoic. Not having angular edges gives the sand some interesting properties when saturated.
@@andywomack3414 subround or round granular stuff is key to making representative simulations. The glass microbeads do the same when you push the pore pressure up. I bet your Mesozoic dune grains had no idea that their future involved scientific investigation!
@@TheGeoModels I doubt it would make good sand for concrete.
Some iron oxide (?) clay adheres to the surface of the grains. The parent sandstone is somewhat friable
Lidar is just about the only cool thing about the 2020s.
Greatest truth on RUclips. I'd like to quote you on that one.
Given the lineup of these features and their association with the fault line, it is clear that they are transverse to the fault. In your model the shaking resulted in scarf formation at roughly right angels to the direction of motion of the shaking. Applying that to the New Madrid fault, the S waves would have been in-line with the scarfs, which is at right angles to your simple model. That suggests to me that the cause of these was not the shearing S waves as you modeled, but rather than compressional P waves. I think it unlikely that it was Love or Raleigh waves, though those need to be ruled out before concluding that it was the P waves that caused them.
It would also be helpful to rerun your model a couple of times using up-down motions centered under your sand mounds, and at the farthest end of the table away from the mounds - to see what the resulting impact is on the mounds. How does the character of the scraping change with each, and with energy levels. You may be able to simulate the Rayleigh waves as well with your setup. Though emulating the Love waves would require using a pliable base that can support the long wavelength land deformation of Love waves. They might though produce similar features and be worth investigating.
All of that needs to tie with estimates of the depth and character of the fault rupture.
Most of our seismic studies are biased and based on near surface shearing fault ruptures as seen in California. These produce very sharp P and S waves and weak Love and Rayleigh waves. New Madrid seems likely to be of that nature, though not necessarily.
The offshore major fault complexes that produce mega thrust earthquakes also have these strong P and S wave structure near to the rupture site, with the P wave generating the tsunami’s associated with the rupture. But at distances 100-400 miles away, the Love and Rayleigh waves dominate and continue for periods of minutes. Huge ground waves result.
Does New Madrid show evidence of that at a distance? In other words, is its character more surface rupture like as in California earthquakes, or megathust like with deeper origin and a different mix of intensities of the four movement types?
So I have messed with different shaking orientations...the result is the same because the microbeads loose frictional strength with acceleration, and the shape of the model "hill" and associated stress field ultimately dictate what failure looks like. It would indeed be cool to deliver energy in different ways, but I think it would be a complete re-write for my simple setup!
I am not versed in the finer points of New Madrid rupture, but it has been studied to death, for sure. i think the seismicity is at a depth range similar to tsunami-forming megathrust quakes. I think there are plenty of coseismic sackungen (spreading hills) in So Cal as well, due to the background geology.
One could logically assume, then, that the bow in the river at New Madrid is the result of an earlier earthquake. Pushing the ground up, just like what happened at Reelfoot Lake. So maybe the big one comes every 400 - 500 years...
'The sides bulged out and the top fell down' is the description of the collapse of the World Trade towers
They found molten metal down there days after... a lot more went on there then meets the eye.
it aint my fault. interisting. wonder how many have heard of the great charlston carolina earthquake that and the 3 new madrid super shocks have always fascinated me esp when no internet , tv or other mass communications , except newspaper and diary accounts of those events .
As a South Carolinian I hear all about the Charleston quake. Plenty of little quakes around Summerville all the time. Not sure if any quake related features are visible in lidar of that area.
I believe it is coming back. Soon
Serpent mound on east coast! 1, 2, 3 Go!
The culture that built it undoubtedly felt a rattle or two, given recurrence interval.
Ok, I realize you are young . . . But this ain't nothin new
Eons ago the Mississippi River flowed north
Yep . . . And it went all the way to Thunder bay
Wut?
And then a cataclysmic geologic event in Missouri changed all that to heading south. If you notice, the souther it gets, the squigglyer it gets.
That's because it had to find a way to get through all the silt deposited in the lake that used to reach from what is now the Tennessee River all the way over to present day Little Rock Arkansas.
Two hints . . . Ya can't make a fence post stand up in Mississippi and they grow rice in the Delta.
Lost count of how many truck drivers I could not convince it really was rice fields.
Well, those folks in Stuttgart could have been lying to us😮
Thank you for pronouncing it correctly. 😊
I do what I can...I try to make sure I don't completely miss the mark with local ways of saying things. For the 1901 landslide video on my page I spent a whole lot of time trying to find a video with someone saying "Gouge" as a place name in western North Carolina. Apparently it is pronounced "goodge," not "gouge" as in jabbing a hole in something. I nearly messed that one up but figured it out in time! I have spent plenty of time in Virginia as well, which is the capital of places that aren't pronounced like you'd think.
EVERYBODY run around and scream 😰....
Looks like the woods on my farm in NC. That is not earthquake generated.
where is this farm
Without showing cross sectional views of the bedding planes (structure and stratigraphy) I don’t think you can say a whole lot based on your sand model alone
MA Drid not Mad Rid... lol
alot of that is just normal weathering
OK NOW WHAT ?
Look up Real Geological maps where ch show you where the 3 wide tectonic rift zones are under the deep sediment!!
It was'nt an earthquake, it was my friends mom falling down. I know I know she's old, really old & really really big.
Sounds like grounds for an insurance claim
We call that, shaky pudding.
Even more shaky pudding in this one:

Reelfoot lake
I need to see it in person someday!
Did this cause the mud flood that buried an advanced worldwide civilization?
I'm thinking/ wondering about this also. The Great Reset? Is this done on purpose with that damned Ice Cube Neutrino Observatory that's buried beneath the snow in Antarctica??? Yeah, it doesn't just detect neutrinos, it feicken makes earthquakes! Tesla invention. Yikes
Look it up, it's insane!
We all gone die together.
GREAT VIDEO thanks for sharing and for what you do.
I pay attention to Prophecy "when israel is divided, God will divide that nation" talking about the 'peace agreement' that begins the final 7 years to Armageddon. So If America is going to be divided it would be here on this 'new madrid fault' and will split the nation all the way to Chicago.
Bless you
IDIOT
Omg, you're so right
There is a scientific theory from the Holy Qur’an that says (and Pharaoh with pegs) and (and the mountains as pegs) means that the pyramids were built to resist earthquakes, and twenty-four sequential pyramids were built in weight and size, starting from Giza to inside Sudan to make a balance in the ground, and that To repel an earthquake that was coming across the Mediterranean Sea and extending its movement into the Red Sea. As for the earthquake in 1992, it occurred because of the heaviness of the waters of Lake Nasser, the effects of which were removed by the opening of the Toshka spillway.
Why is it pronounced MAHdrid and not muhDRID?
The 7 years God Jehovah warned you about. 2017 NW to SE the eclipse crosses over Carbondale illinois (wouldnt know this town if it wasn't for meeting the two gay brothers who live together, screw each other, and mother in Marion who keeps their SS disable check; gee sounds like Sodom). Now 2024 the path crosses like a great big X from SW to NE marking Carbondale as 90 miles north of the New Madrid late-for-quake which was last predicted for an opposite pull of solar and lunar tug (which is how i discovered the matching mythology to 1918bc July 18 sothic star rising with a 7am quake in the year Shem Melkizedek age 550 went to Abram and predicted it in year 452) giving us the magic-X marks the spot from two eclipses 2017/2024 for earthquakes at 7am and 7pm. Already they claim stores will be empty and gas stations too; now add the high alert for 9.0 earthquake and you have an armageddon the people were lured too. As the bible says about ALL armageddons; Jehovah gathers them together and lures them as he does to Gog and Magog. HE says dont forget to notice the comet there beside the sun, and HE says do look for the asteroid which will hit us in 10 months. I'm making sure i have round-trip gas to a smaller town to see it.
This upcoming eclipse seems to have some significance. Even the date screams I'm important. Hopefully, its just another day with some eclipse excitement. Remember when they were clamoring about planet x returning over 10 yrs ago now. Now we have Elon naming his stuff X. Whats he know? Way more then most of us, but who knows what they lied to him about as well because these folks are of their father the devil.
Interesting, I thought gog magog war would happen first given the 7 years lines up nicely leading up to or as the tribulation
So Madrid was likely a major 200 year cycle of sedimentary collecting & exchanging….causing regular activity & 200 year collecting mass movement until several dams pulled back to Missouri River…..
in my opinion I don’t think we’ll have an 1800s, or 1600s problem because the Missouri River is controlled…
But if we lose a few of those probably even one in a domino effect I believe it’s highly likely we could see some domino Fukushima‘s open down the rivers…. If the Ohio ran backwards for three days again we have structural faults from East Liverpool…all the way to Cleveland….
Now look up east Ohio Palestine
