San Francisco Earthquake 1906

July 12, 2010
To better understand the distribution of shaking and damage in the great earthquake of 1906, seismologists have constructed new computer models to recreate the earthquake ground motions. The United States Geological Survey simulations show how the ground moved on each side of the San Andreas fault and how seismic waves radiated away from the fault to produce the shaking. The earthquake, which began two miles offshore of San Francisco, caused shaking and damage along more than 300 miles of the San Andreas Fault. Yellow to red colors indicate regions that experienced damaging shaking. The National Science Foundation is the primary funding source for the SDSC.
