Why San Andreas Fault hasn't produced big LA earthquake for 300 years, according to researchers

- New research has revealed a connection between high lake levels and an increase in large earthquakes along the Southern San Andreas Fault. Despite the potential to produce a major earthquake, the southern pert of the fault has been relatively quiet for 300 years. A study published in the journal "Nature," looked at 1,000 years of history between lake levels and earthquakes in the area and found an 'astonishing' link. A computer simulation was able to replicate the link, which described a connection between high water level and pressure on tectonic plates. Live, local news from L.A.'s Very Own, KTLA 5

I still get chills driving over high overpasses because of that scene.
Uhh, there's a lot more faults other than the mighty San Andreas to worry about.
Yea like the mega fault called cascadia
Exactly. The San Andreas Fault runs right through the western part of the Bay Area but that is not the fault everyone there worries about. Google America's most dangerous fault and the returns you get are for the Hayward Fault.
@@randomhttyddev9245That subduction zone wouldn’t affect a dense population area in California. The largest city that would be impacted is Eureka. The Cascadia Subduction zone would mainly impact Seattle, Tacoma, and Victoria.
The Garlock fault is one we should keep in mind for sure
The "big one" is always 30 years away, like fusion reactors and a mission to Mars.
Bug one was in 1994 actually...I still remember that day like it was yesterday
January 17, 1994 at 0430a. I almost got folded up in a futon in Glendale
That wasn't the San Andreas fault, it was a fault that no one knew about at that time.
@@michael85225 That was a Newly Discovered Underground Fault called the "Chatsworth" Fault or Reseda Fault. The 1971 San Fernando Quake was ALSO caused by an unknown Fault that ended up being named the Sylmar Fault. The Last San Andreas Linked Earthquake to hit The State of California was Loma Prieta in 1989.
The lake dried completely by 1580. Are they saying there were no major earthquakes after that time?? I know of one in 1857.
The Salton Sea was 'created' in 1905.
It makes far more sense that the Salton Sea is preventing a major quake in that region since there hasn't been one since the lake bed was flooded.
That's what I was thinking. This report made no sense and the the fault ends before it goes under the lake. They know where the southern terminus is.
@@ShonnMorristhey are speaking of pre-historic lake cahuilla. also keep in mind that we only have actual historical record of earthquakes going back ~100 years. for all we know there could have been a stretch of 1000 years of no fault disturbance pre 1600 quake, which they found by taking samples of the sediment in different regions of the fault.
Felt 4.4 here in Santa Monica yesterday! Nice jolt!
Water is connected to plate tectonics, of course. However, just because there is no water in the lake does not mean that the plates do not accumulate stress over time.
@@charlesrichter3854 While vertical stress is a factor, what I was referring to is that water lubricates tectonic plate boundaries. The movement of tectonic plates helps relieve heat from inside the planet, and the more water present at a plate boundary, the easier the plates can move past each other. The study does mention vertical stress, but it also says that water from the lake reached deep underground. Therefore, decreased water in the lake basin would mean less lubrication, which would correlate with the plates at this section of the San Andreas Fault having a harder time to slide past each other. Also, the middle section of the fault continues to move, so the longer the southern section of the fault is stuck, the more deformation is accumulated on the plates on this section, and the larger the earthquake that would be unleashed once the fault ruptures. It would be interesting to quantify the contributions of each of these factors to the frequency of fault rupturing though.
We accidentally filled the ancient on and off lakebed in 1905... fort Tejon was 1857, the biggest
Or it could be that the San Andreas has been building up tension after being quiet for those 300 years. Hate to see the day when all that energy will be released.
I will be a happy camper the day it comes

The plates are sliding nicely thanks to a good thick layer of talc !
Talk is cheap, theories are cheap... When it happens We Will Know 😂
The Northridge quake in 94 was on an unknown fault. Hard to compare to San Andreas.
Omg I remember the northridge quake in 94’. I was 3 years old and my dad grabbed me from my bed and ran out while only wearing boxers. I’ll never forget seeing all of my neighbors coming out of there houses panicking. It was in the middle of the night
@@mrstravel9381 Northridge '94 was a Blind Thrust Earthquake that Slipped to the South under the Surface. Sylmar in 1971 was also a Blind Thrust Quake, but it slipped to the North and was a bit closer to the Surface.
The Last Major Quake in California to be indirectly linked and CAUSED by the San Andreas Fault was Loma Prieta in 1989. That was a Strike Slip Fault Quake caused by the Santa Cruz Mountains which are Directly IN the Line of San Andreas.
Whoever wrote this BS obviously didn’t live in LA in 1972 or 1994.
There are dozens of faults in southern california, I know numbers bigger than 4 might confuse you, but this is talking about a quake specifically on the san andreas fault.
72 and 94 were on two different faults not the San Andreas
@@michael85225 71 and 94.
I hope California gets separated from the rest of the country
'The Salton sea dried up due to the drought and diverting of the Colorado river'. What?
I live in NJ, and that’s one thing I’m glad I don’t have to worry about (although there is a small fault line that goes through NJ and NY…nothing like San Andreas). Not quite sure how far the northeast is to either the Caribbean or European plate (or Eurasian). I usually have to worry about hurricanes that vere to the north.
Did you feel the 2011 Virginia earthquake? It was a 5.8 and I felt it very bad 315 miles away in Northern Pennsylvania. You may not have bc of the bodies of water between you and the epicenter but my work building shook heavily, so much so that it had to be inspected after the quake. Theres two major faults in the east that could effect us here by the east coast which is the VA fault and the New Madrid fault near St. Louis. Because the land is mostly flat in the east (the Appalachians not being as tall as the Rockies) we're like to feel New Madrid quakes here also. That little fault you speak of NY/NJ couldnt produce anything significant like the VA fault can. You could see damage from the VA. My building may not have had damage but other buildings in the area did. And I remember feeling shaking as a kid too in this area, even if it wasn't as much as 2011.
So uhh...after that quake that just hit yall in Jersey an hour and a half ago how you feelin about this comment?
How you feeling buddy
We DO need a major cleanup over here. Wouldn’t hurt.
Bruce Lee said you must be like water very well then
It is not just lakes. Changes in ground water level has also been noted in changes in frequency and intensity of earthquakes.
Water? No.
I'm sure it is super glue that has saved the day.
They should just fill all the Lakes in California to test the theory🎤
The one that California should be worried about is the cascade subduction zone. Off the coast of Catalina all the way up to Seattle Washington.
Makes San Andreas look tiny in comparison.
In the Bay Area where the San Adreas Fault does run, it's the Hayward Fault that's considered the most dangerous.
There is no subduction zone faults in or near southern California. The Cascadia subduction zone
up and north of Washington state does end near northern California.
@@johnfranklin5277 it is also important to note that every single time the Cascadia goes off the San Andreas Fault goes off as well shortly after.
It’s a blessing in disguise
Uh, there was no giant earthquake when there WAS a lot of water in the Salton Sea, so that whole narrative is just......stupid.
Well every divot, nook, and crevice is full of water this season. Should be interesting.
can a large LHC stop volcanoes from erupting
I wonder what the rebound of lake Tulare and the refilling of the aquifer in the central valley is going to do.
Most likely nothing, because it’s not near the fault line. The Salton Sea on the other hand is on the fault line.
Shhhhh don't wake it up!!!
Well.. San Andrea's is your Fault!
Sorry I just had to say it.
;)
Oh Bull! Do you know how long the San Andreas is? You can not predict earthquakes.
Plus the southern section of the fault did rupture in the 1812 magnitude M7.4 Wrightwood earthquake, so that would of taken some of the stress away for future earthquakes, also worth bearing in mind!
The only reason is God's mercy. That is the ONLY REASON, but don't get too comfortable.
The central East Coast has a fault line that could produce a massive earthquake too. Called the New Madrid fault line. Because of the topography much of the East Coast would feel it.
The big one will come just like in Northridge
Can we put water back in it?
????????? I hate to disappoint you . They only configured 30 percent of calculations ?????
This doesn't make any sense. The Salton Sea is not even a natural lake having been for a little over 100 years ago by a mistake that flooded the basic with Colorado River water. Also, there are lakes on the fault that were formed by the fault. One such lake just south of San Francisco was known as "Laguna de San Andreas", or San Andreas Lake and it was this lake (really a large sag pond) where the fault takes its name.
The weight of a lake is nothing compared to the weight of all those miles of rock constantly exerting pressure. Something else is going on. This was just a 'publish or die' move by some researcher.
130 years ago the Salton was bone dry . Thanks to a broken levee on the colorado river in the early 1900's it formed again. So much for this "scientific study"
And you think what you just said disproves it? 😂
No, no, no… the narrative has to be that as ridiculous as it sounds to divert all that fresh water into the ocean, the overlords really are doing you a favor. Where’s Stockholm’s syndrome when you need it?! Sheesh!
Um...huh? The Salton Sea is still there...full of water...🤔
The 1974 earthquake film was based on the 1971 Sylmar quake
Salton sea will be a lithium plant soon
The Salton sea was created from a break in the canal of the Colorado River.
California is done with earthquakes. San Andreas has retired ❤❤❤😮
You will be eating your words one day
California will never be “done” with earthquakes… as no where in the world is done with earthquakes. The earth is always moving.
300 years? Was the earthquakes in 2000, 1994, 1989, and 1901 consider 300 years?
Along on the San Andreas Fault.
Only Loma Prieta was a San Andreas fault linked Quake.
I believe the 'big one' is near 8.0.
Salton Sea isnt dried up yet tho.
When I was in high school, the big one was supposed to happen by 2000, but it never happened.
Hurricane Hilary’s dump of water isn’t doing any favors for this theory.
Thanks for the jinx 🤦♂
All speculation and theory, no one knows when the faults will wreak havoc.
We need one to open up under skid row
San andreas is a lake and fault line
Well you all will see
Spoke too soon.
OVER DUE ,
BS What about the many other lakes in Calif?
There will be. There will be!
I hope they didn't actually spend money on that study LOL.
I sure wish it would and finally put California out of its misery, way over due
You have god to thank. Not many made science.
These hilarious stories about ‘why’ are just speculation otherwise how about telling us ‘when’ if they are so smart?
...dah ah 🤨
KTLA5 WTF are you doing? Are you just gonna brush over the 94 quake that broke a bunch of LA freeways? If that's not big, what is?
The Northridge quake was on a different fault, not San Andreas.
@@terencem8795 It was the Chastworth Fault. 1971's was the Sylmar Fault. The LAST San Andreas Earthquake so far was 1989's Loma Prieta/Santa Cruz.

5.3 like 3-4 days ago and 4.4 today, the big ones coming soon
Different fault
@@Show-cv4tx true
Maybe this is actually the opposite and don't want us to freak out lmaooooooooo
White man prophesied the San Andreas fault line
A 8.0 earthquake's impact is nothing compared the disaster created by the Democrats in this state. It would be merciful if one struck San Francisco to put its' habitants & businesses out of their misery.
Hey i dont like this guy’s horrible puns and jokes
lolll he's on here reading your comments
We need it badly...let it be a 8.9 or 9.2😁👌

God gave California time to repent, instead they mocked him, what happens next is on them, judgment is coming!
They are so fake
let’s believe the news 🥱
Sounds like LA is due to get their rocked ! Let's go! Earthquake2023!
Its 2024, so what happened?
I pray it's soon
How about pray that it doesn't happen
