Very useful for teaching about the impacts of natural hazards on humans and their infrastructure, the relationship of earthquakes to plate boundaries and fault lines, and much more, not just in San Francisco, but with applicability elsewhere. Joseph Kerski Earthquakes and Faults in the San Francisco Bay Area (1970-2003) By: Benjamin M. Sleeter, James P. Calzia, Stephen R. Walter, Florence L. Wong, and George J. Saucedo Date: November 19, 2004 Subject: Earthquakes and Faults in the San Francisco Bay Area (Geologic Investigation Series I-2848) Stock # 116286 Price: $7.00 for the map plus $5.00 handling Size: 36 X 48 inches Scale: 1:300,000 The newest earthquake map of the greater San Francisco Bay Area depicts both active and inactive faults and earthquakes with magnitudes of 1.5 to 7.0. Twenty-two earthquakes with magnitudes of 5.0 and greater are indicated on the map and listed chronologically in an accompanying table. The data are compiled from records from 1970 to 2003. The bathymetry was generated from a digital version of National Oceanic and Atmospheric Administration (NOAA) maps and hydrographic data for San Francisco Bay (NOAA). Elevation data came from the U.S. Geological Survey National Elevation Dataset (1 arc-second). Fault data was reproduced from the California Geological Survey, and Earthquake data came from the Northern California Earthquake catalog. The landsat satellite image was produced from seven Landsat 7 Enhanced Thematic Mapper Plus scenes. The map may be viewed and digital files downloaded at: http://pubs.usgs.gov/sim/2004/2848/ This and other earthquake maps, including I-2737 (#28898), "Earthquakes in and near the northeastern United States 1638-1998", and I-2812 (#115886) "Earthquakes in the Central United States 1699-2002" are available from any USGS Earth Science Information Center (ESIC).
