CSI uses the 1906 San Francisco ground shaking recreated by new technology from USGS.

Using three-dimensional geological and seismic velocity models, scientists at the USGS have recreated what they think was the ground shaking due to the 1906 San Francisco earthquake.

Using seismic accelerograms produced by this new technology from the USGS, CSI software has been used to create animations that show the behavior of some California landmarks subjected to the 1906 San Francisco earthquake.

Golden Gate Bridge Subjected to the 1906 earthquake deformation		SF International Airport Terminal Subjected to the 1906 earthquake base isolated structure deformation		Los Angeles City Hall Subjected to the 1906 earthquake base isolated structure comparison with original		San Francisco Marriot Hotel Subjected to the 1906 earthquake deformation
Do not be alarmed ~ the deformations are magnified 100 times and are at twice the real speed.
