CA Earthquake Fault Zones

The California Geological Survey has announced that it has posted its fault zone maps online for the first time. The 547 maps were previously available only in paper or CD formats.

The index map identifies all Official Maps of Earthquake Fault Zones delineated by the California Geological Survey through December 2010 under the Alquist-Priolo Earthquake Fault Zoning Act. Individual Earthquake Fault Zone Maps can be viewed on screen. Digital image files (pdf) and Geographic Information System files (GIS) of individual maps can be downloaded by selecting a specific quadrangle map. MORE INFO
