Faults--Offshore Santa Cruz, California

Metadata Updated: November 12, 2020

This part of DS 781 presents data for the faults for the geologic and geomorphic map of the Offshore Santa Cruz map area, California. The vector data file is included in "Faults_OffshoreSantaCruz.zip," which is accessible from http://dx.doi.org/10.5066/F7TM785G. The offshore Santa Cruz map area lies about 15 to 25 km southwest of the San Andreas Fault, the dominant structure in the distributed transform boundary between the North American and Pacific plates. The map area straddles the right-lateral Santa Cruz Fault zone, a prominent structure west of the San Andreas Fault in the broader San Andreas Fault system. The Santa Cruz Fault zone occurs predominantly in the offshore and extends 400 km from Point Conception on the south to Bolinas and Point Reyes on the north (Dickinson and others, 2005), coming onland at coastal promontories such as Pescadero Point in the map area and Pillar Point, a few km north of Half Moon Bay. In the offshore, the Santa Cruz Fault system forms a distributed shear zone about 2 to 4 km wide that includes two main diverging fault strands. The western strand (also known as the Frijoles Fault) extends offshore from Pescadero Point. The eastern strand (also known as the Coastways Fault or Seal Cove Fault), is mostly onshore in this map area. Cumulative lateral slip on the Santa Cruz Fault zone is thought to range from 4 to 10 mm/yr in this region (U.S. Geological Survey, 2010). The western strand of the Santa Cruz Fault zone (i.e., Frijoles Fault) forms the eastern boundary of the Santa Cruz high. Faults were primarily mapped by interpretation of seismic reflection profile data (see OFR 2013-1071). The seismic reflection profiles were collected between 2007 and 2010.
