Folks:

A wonderful new map just published by the USGS, described below.  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.

Stock #        116286
Price:          $7.00 for the map plus $5.00 handling

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.
