Abstract
 Earthquake Ground Shaking Animation System Track: Mining and Geosciences Author(s): Timothy Mote, John Egan An animation system was developed within the ArcGIS platform to visualize the spatial and temporal variation of earthquake-induced ground shaking. The system helps depict what one feels or would feel during an earthquake--the time history effects of seismic wave arrival, wave amplitude oscillation, and shaking duration. By integrating a GIS of geology, fault rupture, attenuation modeling, and ground motion recording stations to a database of readily available strong-motion datasets, ground shaking time histories across a study area can be produced by time-shifting and amplitude-scaling proximal records. Animations can be developed for observed ground motion datasets from recent earthquakes (e.g., 1989 Loma Prieta, 1992 Landers, or 2004 Parkfield) or for historic and scenario earthquakes from published models (e.g., 1906 San Francisco or Hayward Fault rupture). Funding for this project was provided by the California Department of Conservation--Strong Motion Instrumentation Program.
