Subject: New USGS Geologic Map of the San Francisco Bay region

Number: 06-07 Geologic Map of the San Francisco Bay Region
Date: April 20, 2006
Stock # 206043 (Scientific Investigations Map 2918)
Price: $7.00 for the map, plus $5.00 handling
The San Francisco Bay region is home to 7 million people whose lives are
intertwined with some of the most complex and active geology in the world.
With heightened public awareness about earthquake hazards on the 100th
anniversary of the 1906 San Francisco earthquake, the U.S. Geological
Survey, in cooperation with the California Geological Survey, has produced
a geologic map of the San Francisco Bay Area designed to provide a new
look at the geologic history of the region.
Geologic maps are made by carefully studying the location, age, and
identity of geologic materials in a region, as well as the orientation and
position of geologic structures. This information is compiled in a
Geographic Information System (GIS) that combines a digital map and a
database. The data is then interpreted to "fill in" areas where the
geologic materials and structures are not visible (covered by dense
vegetation or thick soil, for example).
To learn more about this map visit: http://sfgeo.wr.usgs.gov. Included on
this site is an on-line version of the geologic map that can be
downloaded, along with photos, additional information and sites related to
the geologic history in 15 locations around the region.
This map measures approximately 36x48 inches and is available from USGS
Science Information and Library Services (SILS). To place an order, call
the SILS offices at 1-888-ASK-USGS, or visit: http://www.usgs.gov. Orders
may also be placed through the USGS Store at: http://store.usgs.gov
