AB: An animation system for visualizing ground shaking amplitude, oscillations, and duration using existing strong-motion datasets was developed to help interpretation and understanding of strong-motion propagation and attenuation. The system uses readily available strong-motion datasets, geology, seismic velocities, and the ShakeMap model to interpolate ground motions by time-shifting and amplitude-scaling proximal records across a study area. The animation system essentially adds a temporal dimension to the ShakeMap model to visualize the change in measured ground acceleration, velocity and displacement from the earthquake. Three significant historical California earthquake animations were developed with this system (1992 Landers, 1989 Loma Prieta, and 2004 Parkfield earthquakes).
