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

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

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.

I will be a happy camper the day it comes

@@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

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.

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.

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.

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

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.

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!

Most likely nothing, because it’s not near the fault line. The Salton Sea on the other hand is on the fault line.

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.

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.

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.

Different fault

@@Show-cv4tx true

lolll he's on here reading your comments

Its 2024, so what happened?

How about pray that it doesn't happen

​@@gregory7320No it's finally time to put California out of its misery the state is absolutely horrible
