Magnitude 7.8 Earthquake Simulation on the San Andreas Fault

Published 2016-02-09
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.

    We live in Los Angeles, so a 7.8 IS FRIGHTENING ENOUGH! IF Iโ€™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.

    Considering the San Andreas fault is less than two miles from where I live I will have a front row seat.
  • Im in between Oxnard and Santa Barbra so idk how itโ€™s going to affect besides the shaking
  • @minnbeef
    Hmmm, maybe flyover country isnโ€™t so bad after all? ๐Ÿค”
  • @uhadme
    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?
  • @Defenetilynotme
    Hmm i might be in massive trouble because im in san Bernardino
  • @ratgonepostal
    Wait a minute I thought it was going to be a 8.5 mag quake......... explain
