The 1906 Earthquake Simulations


The United States Geological Survey (USGS) has produced some amazing simulations of the 1906 earthquake in San Francisco. Along with the simulations are explanations of how the earthquake happened. And they are using the simulations to understand what they may think is the next earthquake possibility.

This from the USGS:


To better understand the distribution of shaking and damage that accompanied the great 1906 earthquake, seismologists have constructed new computer models to recreate the ground motions. The simulations show how ground moved on the two sides of the San Andreas fault and how seismic waves radiated away from the fault to produce the shaking. The earthquake, which began 2 miles offshore from the City of San Francisco, ultimately grew to cause shaking and damage along more than 300 miles of the San Andreas Fault.

You can view the simulations and the story here.
