Hayward Fault earthquake scenario, ground shaking simulation. This simulation shows the predicted effect of an earthquake of moment magnitude 7.0 on the Hayward Fault (red line) in California, USA. The epicentre is in San Pablo Bay (centre left). The simulation models the maximum peak intensity of ground shaking in the San Francisco Bay and surrounding area, with the colours darkening to red as the shaking intensifies. The shaking spreads as seismic waves radiate away from the rupturing fault line over a rupture distance of 83 kilometres. The colour scale runs from I to IX (scale at bottom left). This simulation is 24 seconds long.
