Significant Earthquakes and Faults
Fault Name Index
Faults of Southern California
Los Angeles Region
This map covers most of the Los Angeles metropolitan area. Within this map area, most every kind of fault type can be found. Indeed, since these maps show only surface traces of faults, some potentially damaging faults -- namely, blind thrust faults, like the one which caused the Northridge earthquake of 1994 -- are not shown. Some of the faults which are shown may never rupture again. This map is not meant to be used as a zoning guide, nor for risk assessment. For these purposes, please see the documents prepared by the California Geological Survey.
