Everyone has heard of the San Andreas fault; the major fault that extends along most of the length of of California. The closest that the San Andreas comes to the Monterey Peninsula is in the San Juan Bautista/Hollister area. Nonetheless, the San Andreas system includes many smaller faults which are localized in the peninsula area.
One of these faults is the Sylvan Thrust Fault. The Sylvan thrust fault consists of a zone of thrust faults that offset terrace deposits in the Monterey foothills. Just below the La Mesa Elementary School, a road cut exposing the Sylvan thrust reveals where several faults have displaced the underlying rock layers. During December 1975 and January 1976, a swarm of 21 small earthquakes occurred near the Sylvan thrust fault zone. The Sylvan Thrust is one of the most active of our local faults and has a relatively high rate of uplift.
