Magnitude 7.8 Earthquake Simulation on the San Andreas Fault

Animation of wave propagation during a magnitude-7.8 earthquake rupturing the San Andreas Fault from northeast to southwest. Red-blue colors reflect the intensity of shaking; green colors indicate areas of permanent ground deformation.
Simulation by Daniel Roten, Kim Olsen, and Steven Day at the Department of Geological Sciences at San Diego State University, and Yifeng Cui at the San Diego Supercomputer Center. Visualization by Daniel Roten (SDSU). Simulation on OLCF Titan.

Honestly, Santa Monica and the Westside looks to get hit much worse than the SF Valley where I live. And Palm Springs? Forget it. I don't understand why people live in Palm Springs. It's a mercilessly hot hell hole. not to mention sitting right on the fault. Hey, we were only a couple miles away from the epicenter in the 1994 Northridge quake. I don't think it's gonna get much worse than that! What's amazing is the Andreas quake takes more than a minute to reach the city of LA. That's a very long time. Oxnard and Ventura also seem to take a significant seismic hit.

Very interesting video

[@user-de4hk2qt6s]

We live in Los Angeles, so a 7.8 IS FRIGHTENING ENOUGH! IF I’m this simulation video the 7.8 can be shown how far it travels, I just wish it would also give the estimate magnitude each area would get hit with.

[@alfredfishFeet6132]

Im in between Oxnard and Santa Barbra so idk how it’s going to affect besides the shaking

[@denelson83]

Don't you mean southeast to northwest?

Hmmm, maybe flyover country isn’t so bad after all? 🤔

Nah Im more screwed im in san Bernardino

[@lylis-dad]

Considering the San Andreas fault is less than two miles from where I live I will have a front row seat.

Earthquake that only lasts for one second, just like the real world.

[@borey123xx9]

What the difference between an earthquake that hits a local area and one that runs up along the entire fault line?

[@Lesloi6227]

What do you think it might be seriously?

[@LoveAllJoy]

It will be different for sure, a little less damage.

[@Defenetilynotme]

Hmm i might be in massive trouble because im in san Bernardino

Water , food, a way to cook with no electricity, how to potty if the sewage breaks. Protection of family. Pet food.

Salton Sea Right? It went off again a couple days ago 10 months later. Its actually the volcanic area there that has mud volcanos that's acting up. Were likely fine hopefully.

[@ratgonepostal]

Wait a minute I thought it was going to be a 8.5 mag quake......... explain

[@Anthony-xp2kl]

Davis Claypool San andreas isnt capaboe of creating anything above 8.0 since it runs 10 miles deep dont believe what the movie san andreas tells u

[@ratgonepostal]

Anthony 1311 I think that San Andreas movie was good but bullshit at the same time. I'm referring to the news media around 20 years ago... Also I had a book once that stated that the 1857 fort tejoin quake was an 8.5 but you look at Wikipedia today it states 7.9. My question is, with all the Hollywood properganda and fake news aside, what's with the downgrade in magnitude? I was brought up to believe that an 8.5 quake was possible on the San Andreas and not the 9 plus that you may have seen in the movie or Japan or Chile.

[@databang]

Anthony 1311, (๑•̆૩•̆) maybe they updated models because USGS says anything above 8.3 is unlikely, not incapable, so maybe Davis's 8.5M is an outlier within the realm of rare possibility.

[@zatannazatara8405]

They now say it's capable of an 8.2

[@ratgonepostal]

@@zatannazatara8405 that the moment magnatude or the instant the fault slip happens producing the p waves or something like that. While, the other say may be correct, I want to know how or why they, the seience community , changed it from 8.5 to 7.8

Damn! LA is fucked lmao

[@Quetzalcoatl_Feathered_Serpent]

Actually its likely Modern LA will surivive the brunt of the Earthquake although its likely anything built around late 50s and before likely won't survive the quake. What LA needs to worry about is the fault underneath the city. The Puente Hills. if that fault wakes up during the big one then yeah LA is screwed.

[@victorr8783]

@@Quetzalcoatl_Feathered_Serpent I think that Puente Hills will probably rupture a few years after the San Andreas

Adam Pondo Yes it is ????

Seriously? Did you sleep through geography?

[@kathrynleveque2046]

@@wannawatchu66 Pasadena is northwest of Santa Ana - I ought to know - I live there. Santa Ana is southeast of Pasadena. We travel west on the 210 and south on the 57 to get there. That is definitely south. I'm curious where you think Pasadena is if not northwest of Santa Ana. I think you need to take a look at a map because you must be thinking about some other city.
