1906 Ground Motion Simulations
Map Views of Ground Shaking
Map-view snapshots and movies show the seismic waves propagating outward from the fault as the rupture expands north and south from the epicenter, which lies offshore from San Francisco. The colors and shading indicate the maximum shaking intensity at each location and the current shaking at the time noted in seconds on each movie frame.
