Description:
Abstract:
This map describes the possible hazard from earthquake-induced landslides for the city of Berkeley, CA. The hazard depicted by this map was modeled for a scenario corresponding to an M=7.1 earthquake on the Hayward, CA fault. This scenario magnitude is associated with complete rupture of the northern and southern segments of the Hayward fault, an event that has an estimated return period of about 500 years. The modeled hazard also corresponds to completely saturated ground-water conditions resulting from an extreme storm event or series of storm events. This combination of earthquake and ground-water scenarios represents a particularly severe state of hazard for earthquake- induced landslides. For dry ground-water conditions, overall hazard will be less, while relative patterns of hazard are likely to change.
Purpose:
The map is intended as a tool for regional planning. Any site- specific planning or analysis should be undertaken with the assistance of a qualified geotechnical engineer. This hazard map should not be used as a substitute to the State of California Seismic Hazard Zones map for the same area. (See California Department of Conservation, Division of Mines and Geology, 1999). As previously noted for maps of this type by Wieczorek and others (1985), this map should not be used as a basis to determine the absolute risk from seismically triggered landslides at any locality, as the sole justification for zoning or rezoning any parcel, for detailed design of any lifeline, for site- specific hazard-reduction planning, or for setting or modifying insurance rates.

Data_Set_Credit:
The authors would like to thank Russ Graymer, Steve Walter and Scott Graham for technical assistance during the map construction. We would also like to thank Ray Wilson and Kevin Schmidt for reviews of the map and manuscript.
Native_Data_Set_Environment:
The databases in this MF were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California). The files are in GRID (ARC/INFO raster data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 7.x). ARC/INFO export files (files with the .e00 extension) can be converted into ARC/INFO coverages in ARC/INFO (see below) and can be read by some other Geographic Information Systems. The digital compilation was done in Arc/Info version 7.1.

Process_Description:
The map construction process is described in detail within accompaning narrative.
In brief, slope was calculated from the DEM. Geologic units were assigned strength parameters. Distance to each pixel in grid was calculated from fault trace. Arias intensity was calculated using equation of (Wilson, 1993) and the calculated distances. Soil strength and slope were used to calculate static factor of safety for saturated conditions. Factor of saftey and slope was used to calculate critical acceleration. Critical acceleration and Arias intensity were combined using the equation of Jibson et al. (1998)
