It was responsible for a large surface-rupturing earthquake in 1968. The fault zone is highly segmented, consisting of seven individually named segments. [3]
The 1968 Borrego Mountain earthquake occurred on April 8, at 18:28 PST in the geologically active Salton Trough of Southern California. The Salton Trough represents a pull-apart basin formed by movements along major faults. This region is dominated by major strike-slip faults one of them being the San Jacinto Fault which produced the 1968 ...
