Electrical resistivity variations associated with earthquakes on the San Andreas Fault
Journal Article

· Science; (United States)
A 24% precursory change in apparent electrical resistivity was observed before a magnitude 3.9 earthquake of strike-slip nature on the San Andreas Fault in central California. The experimental configuration and numerical calculations suggest that the change is associated with a volume at depth rather than some near-surface phenomenon. The character and duration of the precursory period agree well with those of other earthquake studies and support a dilatant earthquake mechanism model.
