@@Ohmanwhyyourfeelingshurt The NWS reports that a minor tsunami occurred at the Arena Cove tide gauge. It does seem like something may have happened, but the data from there is notoriously noisy. Eureka and Crescent City reported no tsunami. The "buoy" GeologyHub refers to, which I think is DART station 46411, did not record a tsunami. It recorded seismic waves from the M4.7 aftershock that happened minutes later.
I think the explanation is very realistic. This can help to relax people living there because I think it s plausible this will not be followed by a big one and also the tsunami danger was limited
I had slept in and was only awake 5 minutes before the shaking began, it was terrifying. Once it stopped i immediately got dressed, grabbed my go bag full of supplies and food, and headed for higher ground. Thankfully no tsunami came but I now feel confident in my quick reflexes for if another threat like this occurs
Because the news is entertainment. They need to make sure you still have questions or concerns after 3 days of coverage, so you'll come back. Nvm the fact that they could cover most of it in under 6 minutes l.
100% To be fair, they are reporters not geologists. They are also on a broadcast schedule. Their job is to fill up that airtime with the best information they have at the time. And if they don’t have good information, then just fill up the space with whatever they’ve got. In this case, a crack in the road, some paintings shaking on a wall and a pool sloshing around.
Lol....... Here in Wellington, NZ, the local council had a quake response exercise a few years ago called "It's Our Fault", referring to the Wellington Fault which goes through the western part of the city and along the west of the harbour.
As someone living in the area, my biggest concern isn't that this is a foreshock, but that it will put additional strain on the Cascadia Subduction Zone and ultimately trigger a megathrust quake. The problem with this is, unlike a foreshock, the 'main' quake doesn't need to be a few weeks or a month down the road - it can just 'speed up' the timeline to the next big one.
It needs to be assumed that the big one will happen, and prepare accordingly - from someone who lives near the Alpine Fault in NZ, waiting for our big one.
I hate to break it to you, but Cascadia is an inevitability. It's not at all a case of if, just a case of when. Your only hope of missing it, is moving away, or dying of other causes.
@@riverAmazonNZ Oh I assume it. I think about it just about every day. But it could be 50, or 100, or even 150 years down the road. But anything that places stress on the system is likely just going to accelerate that timetable.
As someone in Crescent City, we barely felt the quake (we did get the shake alert warning a few seconds before). It was concerning that the magnitude kept rising from an initial onshore 6.0 to a 6.7 offshore to a 7.3 where the current epicenter is then down to 7.0 later. I had to evacuate when the sirens went off given my office location was destroyed in the 1964 tsunami. Thankfully, nothing significant happened, but it was a very good practical test.
I was on my sailboat anchored in San Francisco (Aquatic Park) when the warning went out. I hightailed it across the bay as fast as my boat would go to a safer anchorage. Thankfully it was just a false alarm and a good opportunity to test emergency preparedness.
Don't anchor your boat! You'll be 'tethered' to the sea-floor when/if a tsunami arrives. Just keep heading AWAY from land and you won't even notice the tsunami!
Was sitting in my car at a coffee shop drive-thru in Arcata.. phone alarm went off then car started bouncing round. Could hear a barista saying "it's a good one guys!" from inside.. the building was bouncing a bit as well. Tsunami alarm went off and folks mostly ignored it. I went to higher ground. 🤷♂️
Strike/ slip is good for close coastal earthquakes. Much less crust vertical movement, meaning much smaller generated tsunamis close to the coast. Close coastal underwater earthquakes are easily the most dangerous, as they mean virtually no warning time for evacuations.
Generally, when Californians talk about "the Big One" we're referring to the San Andreas Fault between the Pacific Plate and the North American Plate, not on the Juan de Fuca Plate.
There is nothing "gentle" about a mag 7 earthquake. The 1906 quake that destroyed San Francisco was 7.9, the 89 quake that delayed the world series collapsed several bridges and scared the crap out of everyone was 6.9. It right about the average size that has been practically leveling cities across the world over the last decade.
BS. .9 is nine x .0 Cities are in DIRE need of significant leveling. Watching tres sway or cracks appear is NOT "scare the crap" Move to alabama or someplace where everyone is scared the crap of everything. I am about 30 miles from this COMMON event epicenter. Smooth versus sudden quaking tells whether it is transverse slip or subduction. Please take your crap back to your fiction watching and keep It to yourself.
I heard from someone that there was a tsunami alert and I thought it odd there hadn't been anything about it from Geology Hub. Then I looked at my phone and here it is! Thank you for keeping us up to date. 😃🖖❤️❤️
Me too. I watched several news reports soon after and they had no understanding other than to say "California has a lot of fault zones and is prone to earthquakes". 🤦

Is it possible that this earthquake, while not a foreshock, could put additional strain on the cascadia subduction zone, possibly accelerating the timeline of the next big earthquake?
probobly, but theres been lots of earthquakes in the past there, like the 7.1- 7.2 quake in 1992 at the mendocino triple junction, none set off any activity in Cascadia
I am no expert but I live in the Zone so I have read up on it a bit. These local quakes can do one of two things: 1) Release stress and delay The Big One or; 2) Release stress and trigger the rest of the fault bringing on The Big One sooner. Hope that helps.
The expected 9.0+ Cascadia EQ centered off the Oregon Coast would be 100x more intense and 10x longer in duration (@3 minutes) than this 7.0 EQ. Most roadways and bridges would be impassable. Check out the Anchorage pics of the 1964 Great Alaska EQ, near total devastation; plan accordingly.
As long as one of these Douglas fir trees doesn't fall on my house I'll be ok. Northridge earthquake shook me out of CA. So where did I run to? Oregon. No brains!
Thank you for presenting the information about yesterday's earthquake and tsunami at the Mendocino Triple Junction. I did not feel the earthquake but got the tsunami alert. When it was cancelled I just assumed that one had not been generated. Interesting to know that one had been generated but was just small due to strike-slip fault.
I've never knowingly experienced an earthquake until yesterday! We felt what is maybe comparable to a magnitude 2.0-3.0 in Klamath Falls, OR. I got the USGS emergency alert just a minute after the earthquake was detected and less than a minute before the blinds and anything hanging started swaying. Very cool experience for me
That Cascadia subduction zone is outright scary last time a megathrust quake struck was in 1700 Mendocino Juan de fuca north American pacific plates meet
Alert system worked as designed. BTW it wasn’t state wide. It is designed to alert you if your in range of damaging effects or significant effects. Basically if you can feel it. PS - In SoCal we didn’t get alert as designed. My friends north of the Bay Area got alerts
Eureka resident here. ShakeAlert absolutely failed in my case. I felt the quake, grabbed my phone, and then the alarm went off at top volume. I killed it, went to find my kiddo, and the alarm blared again while the quake continued. Killed it again while we were dealing with the shaking and it blared for a third time. I am never phased by quakes and actually enjoy them, usually, but the obnoxious alarm absolutely kicked up the panic like five notches. First thing I did when things settled down was to turn that crap off with a vengeance. NOT HELPFUL.
@@stonefeathers In Stockton, we just got the quake alert, but nothing for the tsunami. Given what they thought was going to happen, similar to the 2011 tsunami, we should've been alerted for that. Marinas, boats and docks, were significantly damaged in that one here. Good to hear you're prepared and calm in these situations. Hopefully ShakeAlert will fix the bugs. 🍀😎
Got tsunami alert in South Bay, didn’t feel the quake.

I live about 40 miles from the epicenter and I'm also in the tsumani zone. As such, I always keep a GO bag in my car packed with all the essentials I would need to survive for about a week or so. Ironically, I was getting ready to trade my car in for a new one that day, and in preparation, I had emptied it out the night before, including the GO bag. Probably the first time in 5 years that I was without it. I even remember thinking, "I hope we don't have an earthquake tomorrow". The earthquake hit as I was standing with the salesman looking at a new car. Fortunately, the earthquake was a "roller" rather than a shaker, more like being on a boat in a mild swell or standing on a field of jello. The shakers are horrible. Even much smaller ones can knock you to the ground and they do a lot of destruction. This one felt like it lasted about 2 minutes. The place we were was right next to the bay with a lot of flat all around us. You could see it moving, sort of like a huge bowl of jello that had been knocked. Definitely a LOT of power! As soon as it was over, I got in my car and drove to high ground, and waited an hour for the all-clear. As of today, I have a new car, and my GO bag is securely stowed inside it.
We don’t really have one impending Big One, rather, each part of the state has their own Big Ones to anticipate. The far North and North Coast has the Cascadia subduction zone Big One. The Bay Area and NorCal have the Hayward fault Big One. Central and Southern California have the southern segment of the San Andreas as their impending Big One.
I was sleeping when my wife came in and woke me up. She’d gotten the tsunami warning and it was alarming. Technically we were in the tsunami warning zone but at roughly 30 miles inland from the Golden Gate and 180 ft above sea level it would’ve had to have been a massive tsunami to reach us. I wasn’t sure if we’d feel the shaking. We didn’t. There were shaking reports in San Francisco but I’m doubtful it was felt there. Surprisingly the shaking intensity was very local. By comparison the Loma Prieta in 1989 was felt all over the entire region.
I live in SoCal and got no such alert. Small correction about the scale of the alert system here, it doesn't get shared to everybody they have it set up so that it only gets sent to relevant areas.
Thank you for the excellent presentation! Following yesterday’s events, I have published a simulation on my channel that illustrates the estimated ground shaking that could affect the Los Angeles area if the Big One strikes.
Dear Tim Catron, Your volcano and related phenomena audio visual short programs are being much enjoyed. This evening, I was pleased by Your interview with S.Willsey. It was good to see You as the genuine person behind Your videos. My impression of the materials offered having a strong ethical underpinning, and, as well, the depth and breadth of information shared, are helping me to feel better connected to these natural and dramatic events. Thank You. Edwin
The triple plate junction called the Mendicino Triple Junction is the most seismically active place along the West Coast. Depending on which plate is moving and where, it can produce a tsunami but that didn't happen in this case. The Juan de Fuca plate and Pacific plate are in a slip strike relation at that point but if it happened further west where the Pacific plate and the Juan de Fuca plate are spreading apart deeper in the Pacific that would be a tsunami making event. You can see the many parallel mountains under the ocean in the video where that has happened in the past.
A reminder of why I subscribed to this channel. Good work here. I was in the woods near the epicenter when it struck. Very different experience being out in the woods, than being indoors. Trees shook pretty good but nothing came down. Scary event for me, out in the middle of nowhere by myself.
Here on the Monterey Bay, we got the warning as well. Came as a bit of a surprise as everyone's cell phones sounded with the warning tone at the same time - scared the heck out of a bunch of us.
Living very near the epicenter of the 7.0 quake, it Was a big quake, but didn’t have near the damage as several recent 6+ quakes. Living near the triple junction is not boring. LOVE the channel.
18 hours ago a Basin and Range quake occurred. The basin and range is an area of stretched crust, the Pacific plate is pulling the North America plate creating the basin and range area, so this is amazing to catch the real deal at play, Pacific plate moves creating a quake, Basin and range then follows creating a follow-up quake. Really beautiful to see the process so clearly.
Excellent video. Thank you. I was in the Bay Area near the bay at work. My company (a large organization and campus) had no plans for a Tsunami event. The warning was disturbing as the bay communities normally don't get such a thing. Thought that it was something the costal areas had to worry about/ prepare for.
In 2016 i was in Crescent City and the guy at the visitors center told me that because of the severe damage from a tsunami in 1964 they had rebuilt the harbor to be tsunami restitent . He then surprised me by saying " and i can't wait to try it out". I bet he got excited by this
According to the New York times the March 2011 tsunami caused tens of millions in damages to Crescent City, CA. The 8 foot swell destroyed all the docks and sank 16 boats. The Pacific Ocean bathtub was still rocking back and forth a week later. ( Where was that guy and how did he miss the 2011 tsunami with all that damage ?? )) 😆
YES ! WE FINALLY GOT ON HUB ! Thank you Hub ... But rolled nice and easy thru Humboldt University, no tidal surge was noticed. ... What was different were the hundred aftershocks and swarms of quakes southeast in Cobb and as far south as the Geysers past Lake County ... seems Juan de Fuka plate was shoved a bit further under North American plate ?
Interesting. I saw the location towards the bottom of the Juan de Fuca zone and size around 7 and thought it was just one of those deep ~7s a subduction zone will generate occasionally, and that it was the depth and distance keeping it from being such a big deal compared to what one usually expects of a 7.
A very concise and accurate description of the event. The epicenter was just 0.4 miles deep, so they dodged bullet as far as shaking goes. But I agree, there was no tsunami danger there. Lots of people felt it, though! Good job!
I was in the 1992 Cape Mendicino 7.2 magnitude quake. The entire county rallied quickly to help the victims in Ferndale, where large channels of ground had given way. Never seen anything like it since.
Random facts: I read this week that the 1960 Chile earthquake and the 1964 Alaska earthquake generated waves of almost 4 feet at the Presidio in San Francisco.
I was happy to see you posted about this so I could be proud of my text to a friend in Cali stating, "There won't be a tsunami on the San Andreas fault because it only has horizontal movement, not vertical." LOL - you humbled me with your explanation, and I thank you for the education!!! But officials sending out false alarms does harm. Today it seems 'erring on the side of safety' and doing things 'out of an abundance of caution' is the norm but, in many, it also takes away any integrity the warnings previously held. Many may ignore the next warning. Some may have done harm in the panic following the warning (car accidents, boat accidents, stress, etc.). Officials must use facts, not feelings in calling emergencies. Thank you for the video!!
Do they immediately know which fault produced the quake out of the 3 that converge there? As I understand it the time lost making the determination could cost lives. Better safe than sorry when only 1 out of the 3 is lower risk.
That is where I live, my daughter had just gotten into my pickup after an optometrist appointment. At first we thought we just shut our doors too hard, within 2 seconds we knew it was an earthquake (benefits of living in one of the most seismically active areas on the planet). It really wasn't bad at all. It was more a roller than sharp jolts like others. I took her back to school and I went back to work. We have had much more damaging quakes. Even my cats didn't have an issue really.
I was anticipating this video. Your explanations and coverage are much better than the local coverage, especially the USGS. I'll give the woman doing the initial report some grace for maybe being put on the spot or nervous, but she couldn't even remember the geology of the location.🤦Epic fail IMHO. If it were me, I'd be making a follow-up video showing I actually possessed that professional knowledge. It just goes to show that the geologists need to be prepared, maybe even trained, for doing media coverage of these events. I'm glad the quake's impact was less than expected, though I feel for those whose homes or businesses were damaged. Again, your coverage was much better than those folks on air yesterday. Perhaps the USGS should call you next time. 💚✊🌎
Someone has mentioned the Cascadian subduction zone in the comments. Could you explain if this could put more strain on it, accelerating the timeline? Although from the looks of it, it's somewhat "overdue" already?
Interesting info on tsunamis and plate techtonics, Thank you! As I listened, I thought, "A gentle "shot across the bow" as we say on the east coast... hopefully those areas will still take heed of the warning.
This earthquake relieved stress between the Juan de Fuca plate and the Pacific plate. Did this event increase the stress on the Cascadia fault between the North American plate and the Juan de Fuca plate?
I was in the San Francisco area when this happened, Redeo California, it's on the East Bay. Because of driving I didn't even know an earthquake happened Even though the shake alert said it was coming, the phone made no noise, because of what I do I have two phones and both of those start freaking out with the tsunami warning. My wife got down in Bakersfield California got no warning about the earthquake and obviously no warning about the tsunami.
Earthquakes in this area are common. Those 3 tectonic plates are always moving. My friends who still live in Ferndale said it was messy but minimally damaging. We’ve survived the 3 earthquakes in 1992, which did a lot of damage.
I felt my 4th floor office in Santa Clara CA, at the southern end of the San Francisco bay sway back and forth for a while. The chains for the window blinds clicked back and forth for several seconds. The trees outside moved, too.
I'm from california and work next to the ocean, it's literally right across the street from my building. This was quite a scare. I saw birds still sitting on the water and the water didn't seem to recede, but I got out of there anyway.
I'm from the US but not Cascadia Subduction Zone and California area but I am hoping this "big one" doesn't happen because it will wreck havoc to most of California and Canada and would be devastating. I hope it doesn't happen but it likely will and we just need to pray that we are protected.

Because the news is entertainment. They need to make sure you still have questions or concerns after 3 days of coverage, so you'll come back.
Nvm the fact that they could cover most of it in under 6 minutes l.
Heck, they could make an entire time block reporting on just the stuff falling off of store shelves.

The best place to be in a tsunami is out to sea, not tethered to an anchor. That would have pulled your boat over.

Strike/ slip is good for close coastal earthquakes. Much less crust vertical movement, meaning much smaller generated tsunamis close to the coast.
Close coastal underwater earthquakes are easily the most dangerous, as they mean virtually no warning time for evacuations.

Central and Southern California have the southern segment of the San Andreas as their impending Big One.
You are absolutely right.
I personally live near the Hayward fault. It scares me big time.
I was sleeping when my wife came in and woke me up. She’d gotten the tsunami warning and it was alarming. Technically we were in the tsunami warning zone but at roughly 30 miles inland from the Golden Gate and 180 ft above sea level it would’ve had to have been a massive tsunami to reach us. I wasn’t sure if we’d feel the shaking. We didn’t. There were shaking reports in San Francisco but I’m doubtful it was felt there. Surprisingly the shaking intensity was very local. By comparison the Loma Prieta in 1989 was felt all over the entire region.
My condolences to those who lost items knocked off shelves.🥀
imagine being the worker who has to restock all the store shelves, couldnt be me
There's videos of bongs smashed on the floor of a store. The comments were truly heartbreaking.
😅
@@outlawbillionairez9780 Oh for a link to that one!
@@outlawbillionairez9780 I didn't see that one, but there is one of a grow greenhouse with all the plants shaking....
I always come here for "truth" data in the aftermath of any geologic event 🤙👍
Thumbnail.” tsunami strikes!”
Truth data?😂🤣😂🤣
Thanks as always, Geology Hub!
I live in SoCal and got no such alert. Small correction about the scale of the alert system here, it doesn't get shared to everybody they have it set up so that it only gets sent to relevant areas.
Same. I don't live here but as a current local cell tower user at the time, no alert was given. I was in south central CA at the time.
Thank you for the excellent presentation! Following yesterday’s events, I have published a simulation on my channel that illustrates the estimated ground shaking that could affect the Los Angeles area if the Big One strikes.
Dear Tim Catron,
Your volcano and related phenomena audio visual short programs are being much enjoyed.
This evening, I was pleased by Your interview with S.Willsey.
It was good to see You as the genuine person behind Your videos.
My impression of the materials offered having a strong ethical underpinning, and, as well, the depth and breadth of information shared, are helping me to feel better connected to these natural and dramatic events.
Thank You.
Edwin
The triple plate junction called the Mendicino Triple Junction is the most seismically active place along the West Coast.
Depending on which plate is moving and where, it can produce a tsunami but that didn't happen in this case. The Juan
de Fuca plate and Pacific plate are in a slip strike relation at that point but if it happened further west where the Pacific
plate and the Juan de Fuca plate are spreading apart deeper in the Pacific that would be a tsunami making event. You
can see the many parallel mountains under the ocean in the video where that has happened in the past.
A reminder of why I subscribed to this channel. Good work here. I was in the woods near the epicenter when it struck. Very different experience being out in the woods, than being indoors. Trees shook pretty good but nothing came down. Scary event for me, out in the middle of nowhere by myself.
Here on the Monterey Bay, we got the warning as well. Came as a bit of a surprise as everyone's cell phones sounded with the warning tone at the same time - scared the heck out of a bunch of us.
Simultaneously a 5.8 on Cobb mtn next to the Mt Konocti Volcano situated above the volcanic field.
it got downgraded to a 4.3 (i dont know how they overestimated it that much)
@descai10 reported only 1 mile deep. The lava field the geysers work on is about that far down.....
Oh wow. I felt it all the way down in chico, didn't realize how bad it was up there. Sounds like it could have been a lot worse though.
Good job explaining. All my questions are answered.
Quite happy to wait for your analysis as all the locals went crazy.
Superb explanation--thank you for the clear and diligent work!
That’s my hometown of Eureka.
Living very near the epicenter of the 7.0 quake, it Was a big quake, but didn’t have near the damage as several recent 6+ quakes. Living near the triple junction is not boring. LOVE the channel.
18 hours ago a Basin and Range quake occurred. The basin and range is an area of stretched crust, the Pacific plate is pulling the North America plate creating the basin and range area, so this is amazing to catch the real deal at play, Pacific plate moves creating a quake, Basin and range then follows creating a follow-up quake. Really beautiful to see the process so clearly.
Could you possibly do a video on the earthquakes the Chixulub impact caused? I had heard somewhere that they lasted for weeks.
Excellent video. Thank you. I was in the Bay Area near the bay at work. My company (a large organization and campus) had no plans for a Tsunami event. The warning was disturbing as the bay communities normally don't get such a thing. Thought that it was something the costal areas had to worry about/ prepare for.
This is a channel I really like to pay attention to, especially now that he's talking about something that I actually experienced.
Thanks for keeping us updated on the latest rattlings.
In 2016 i was in Crescent City and the guy at the visitors center told me that because of the severe damage from a tsunami in 1964 they had rebuilt the harbor to be tsunami restitent . He then surprised me by saying " and i can't wait to try it out". I bet he got excited by this
According to the New York times the March 2011 tsunami caused tens of millions in damages to Crescent City, CA. The 8 foot swell destroyed all the docks and sank 16 boats. The Pacific Ocean bathtub was still rocking back and forth a week later. ( Where was that guy and how did he miss the 2011 tsunami with all that damage ?? )) 😆
YES ! WE FINALLY GOT ON HUB !
Thank you Hub ... But rolled nice and easy thru Humboldt University, no tidal surge was noticed. ... What was different were the hundred aftershocks and swarms of quakes southeast in Cobb and as far south as the Geysers past Lake County ... seems Juan de Fuka plate was shoved a bit further under North American plate ?
Great video thanks for touching on the Mendocino Triple Junction. I was wondering how close the earthquake was to the junction!
That Mendocino plate line is really straight
Thanks for sharing this very informative video. 😊
I was at work in Southern Oregon when the USGS alert sounded in my phone!
That Juan de Fuca Plate seems to be quite the trouble maker
Very naughty boy.
Imagine running for your life when U get the tsunami warning - then it's less than 5 inches big!!! 😅🏃
imagine ignoring it and getting a 50 feet wave. I hope you survive.
@RoseNZieg
I'll survive for sure- I'm so paranoid about a tsunami, I won't even live 100 miles near the ocean!! 😅
Great summary!❤thank you.
Good, clean work, Timothy.
Interesting. I saw the location towards the bottom of the Juan de Fuca zone and size around 7 and thought it was just one of those deep ~7s a subduction zone will generate occasionally, and that it was the depth and distance keeping it from being such a big deal compared to what one usually expects of a 7.
Very interesting, thank you.
A very concise and accurate description of the event. The epicenter was just 0.4 miles deep, so they dodged bullet as far as shaking goes. But I agree, there was no tsunami danger there. Lots of people felt it, though! Good job!
Thanks for the update.
I was in the 1992 Cape Mendicino 7.2 magnitude quake. The entire county rallied quickly to help the victims in Ferndale, where large channels of ground had given way. Never seen anything like it since.
thank you so much for this video, there's like a hundred local news videos that explain literally nothing and fear monger about nothing
Random facts: I read this week that the 1960 Chile earthquake and the 1964 Alaska earthquake generated waves of almost 4 feet at the Presidio in San Francisco.
My brother got stranded in Fairbanks because of the 1964 quake. My parents found out he was okay only because of a ham radio emergency traffic net.
Thank you for this presentation.
When I first heard about this I was hoping that the Cascadia fault line was unzipping
Wait wtf 0:01 what even is that? Are those mudstone concretions? Can you imagine the fossils!
Excellent explanation
I was happy to see you posted about this so I could be proud of my text to a friend in Cali stating, "There won't be a tsunami on the San Andreas fault because it only has horizontal movement, not vertical." LOL - you humbled me with your explanation, and I thank you for the education!!! But officials sending out false alarms does harm. Today it seems 'erring on the side of safety' and doing things 'out of an abundance of caution' is the norm but, in many, it also takes away any integrity the warnings previously held. Many may ignore the next warning. Some may have done harm in the panic following the warning (car accidents, boat accidents, stress, etc.). Officials must use facts, not feelings in calling emergencies. Thank you for the video!!
Do they immediately know which fault produced the quake out of the 3 that converge there? As I understand it the time lost making the determination could cost lives. Better safe than sorry when only 1 out of the 3 is lower risk.
Good update! Thank you for sharing :)
Thanks, I hoped that you make an video on this earthquake 😊👍
I spent many days diving that area. The Lost coast is local name. King Mountain Range towers over that area.
That is where I live, my daughter had just gotten into my pickup after an optometrist appointment. At first we thought we just shut our doors too hard, within 2 seconds we knew it was an earthquake (benefits of living in one of the most seismically active areas on the planet). It really wasn't bad at all. It was more a roller than sharp jolts like others. I took her back to school and I went back to work. We have had much more damaging quakes. Even my cats didn't have an issue really.
I was anticipating this video. Your explanations and coverage are much better than the local coverage, especially the USGS. I'll give the woman doing the initial report some grace for maybe being put on the spot or nervous, but she couldn't even remember the geology of the location.🤦Epic fail IMHO. If it were me, I'd be making a follow-up video showing I actually possessed that professional knowledge. It just goes to show that the geologists need to be prepared, maybe even trained, for doing media coverage of these events.
I'm glad the quake's impact was less than expected, though I feel for those whose homes or businesses were damaged.
Again, your coverage was much better than those folks on air yesterday. Perhaps the USGS should call you next time. 💚✊🌎
The networks revel in fear mongering!
Already had a couple of magnitude 5s, many 4s, and tons of smaller ones
This could’ve been the big one
What is more creepy is I just watched a video of a 7.2 earthquake taking place in the ocean with scuba divers a day before this happened 😮😮😮😮
News channels are not reporting this
and the oregon coast got alerted too
I got a notification on my phone yesterday and I live in Eugene Oregon. Got a second notification much later ib the day at around 11 pm while working
Someone has mentioned the Cascadian subduction zone in the comments. Could you explain if this could put more strain on it, accelerating the timeline? Although from the looks of it, it's somewhat "overdue" already?
Interesting info on tsunamis and plate techtonics, Thank you!
As I listened, I thought, "A gentle "shot across the bow" as we say on the east coast... hopefully those areas will still take heed of the warning.
This earthquake relieved stress between the Juan de Fuca plate and the Pacific plate. Did this event increase the stress on the Cascadia fault between the North American plate and the Juan de Fuca plate?
One day later and we all have almost forgotten about yesterday's earthquake.
I was in the San Francisco area when this happened, Redeo California, it's on the East Bay. Because of driving I didn't even know an earthquake happened Even though the shake alert said it was coming, the phone made no noise, because of what I do I have two phones and both of those start freaking out with the tsunami warning. My wife got down in Bakersfield California got no warning about the earthquake and obviously no warning about the tsunami.
Earthquakes in this area are common. Those 3 tectonic plates are always moving. My friends who still live in Ferndale said it was messy but minimally damaging. We’ve survived the 3 earthquakes in 1992, which did a lot of damage.
Just FYI, you seem to have gotten the link to EarthquakeSim wrong. Looks like there's an accidental "if" at the end there.
I felt my 4th floor office in Santa Clara CA, at the southern end of the San Francisco bay sway back and forth for a while. The chains for the window blinds clicked back and forth for several seconds. The trees outside moved, too.
Yay, details!
I am up the coast in Canada, heard very vague information up here
Great coverage felt it in McKinleyville strong but short a few after shooks than just quiet ❤❤❤❤
One day there will be a Big Rip (magnitude 9.0). If you live on the west coast, prepare yourself.
I'm from california and work next to the ocean, it's literally right across the street from my building. This was quite a scare. I saw birds still sitting on the water and the water didn't seem to recede, but I got out of there anyway.
I'm from the US but not Cascadia Subduction Zone and California area but I am hoping this "big one" doesn't happen because it will wreck havoc to most of California and Canada and would be devastating. I hope it doesn't happen but it likely will and we just need to pray that we are protected.
