U.S Geological Survey and the Southern California Earthquake Center.
These compelling earthquake simulations show ground movement and wave propagation as an earthquake rupture propagates along the San Andreas Fault. These simulations are from the Great Southern California ShakeOut earthquake drill conducted in 2008. The animations capture the shaking at length scales larger than about 300 ft (100 m) and provide detailed animations of the shaking for this scenario earthquake. Several different views are available. The files are QuickTime and are available in three different resolutions.
