Oroville earthquakes: normal faulting in the sierra nevada foothills
Authors:Bufe C G  Lester F W  Lahr K M  Lahr J C  Seekins L C  Hanks T C
Abstract:Aftershocks of the Oroville, California, earthquake of 1 August 1975 define a 16- by 12-kilometer fault plane striking north-south and dipping 60 degrees to the west to a depth of 10 kilometers. Focal mechanisms from P-wave first motions indicate normal faulting with the western, Great Valley side downdropped relative to the Sierra Nevada block. The northward projection of the fault plane passes beneath Oroville Dam and crops out under the reservoir.
