California Shaking
Between the rampant wildfires and last week’s Great Southern California ShakeOut (an earthquake drill), I’m glad I chose to make my home in Washington, D.C. instead of Los Angeles. Here there are no earthquakes, no fires and only the occasional hurricane. What really got my attention last week, though, was an animation from the USGS of a magnitude 7.8 scenario earthquake on the San Andreas Fault in southern California. The worst of the seismic waves travel north along the fault, but some of the most intense shaking also heads straight for Los Angeles. Here’s the animation that shows the seismic waves traveling: And here is another animation, 1000 times exaggerated, that shows how the seismic waves will shake LA: More simulations are available at the USGS's site.
