Seismic hazard maps are used to predict how much shaking an earthquake will produce and in designing earthquake-resistant buildings. It’s therefore important that these maps be accurate. This project will focus on creating an oral history collection of shaking observations from witnesses of two earthquakes, the 1992 Joshua Tree and 1993 Big Pine, California earthquakes. It will also collect information in contemporary newspaper accounts. Comparing this historic shaking data to the maps will allow researchers to verify and improve them.
