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.

The data used in the construction of this map were published by
the USGS between 1969 and 1999. Transformation of this data was
performed in 2000. The date of construction should be considered

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.
