The USGS Coastal and Marine Science Center (formerly the USGS Center for Coastal Geology) has three sites, one for the Atlantic Ocean (located in Woods Hole, Massachusetts), one for the Pacific Ocean (located in Santa Cruz, California) and one for the Gulf of Mexico (located on the University of South Florida's St. Petersburg campus). The goal ...

California Coast, Los Angeles to San Diego Bay. The Elsinore Fault Zone is labeled in the center running along the Santa Ana Mountains. NASA photo, 2008. The Elsinore Fault Zone is a large right-lateral strike-slip geological fault structure in Southern California.
150 photos included in The California Coast from the Air (2014) by Gary Griggs and Deepika Shrestha Ross. [12] Photos of Fort Funston near San Francisco were used by the U.S. Geological Survey (USGS) to test a method of calculating the amount of coastal erosion. [13] [14]
The US Geological Survey defines the geographic center of California about 7.1 miles (11.4 km) driving distance from the United States Forest Service office in the community of North Fork. Earth scientists typically divide the state into eleven geomorphic provinces with clearly defined boundaries.
Along just the Southern California coast, the cliffs could erode more than 130 feet by the end of the century if the sea keeps rising, according to recent projections by Barnard and his team.
The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
The 2003 San Simeon earthquake struck at 11:15 PST (19:15 UTC) on December 22 on the Central Coast of California, about 7 miles (11 km) northeast of San Simeon. Probably centered in the Oceanic fault zone within the Santa Lucia Mountains, it was caused by thrust faulting and the rupture propagated southeast from the hypocenter for 12 miles (19 km).
