ABSTRACT
In April and May of 1998, personnel from the United States Geological Survey (USGS) conducted a field reconnaissance in the San Francisco Bay area to provide a general overview of landslide damage resulting from the 1997–1998 sequence of El Nino-related storms. Seven scientists from the USGS Landslide Hazards Program based in Reston, Virginia, Golden, Colorado, Menlo Park, California, and five scientists from the USGS Geologic Mapping Program’s San Francisco Bay Mapping Team based in Menlo Park, California, cooperated in the landslide damage assessments. The assessments were done for 10 counties in the Bay area: Alameda, Contra Costa, Marin, Napa, San Francisco, Santa Clara, Santa Cruz, San Mateo, Solano, and Sonoma. In addition to the efforts of USGS scientists in providing data from the field evaluation, each of the counties, many consultants, and others cooperated fully in providing the landslide damage information summarized here.
