It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. Ī map displaying each of the seven major faults in the San Francisco Bay Area, and the probability of an M6.7 earthquake or higher occurring on each fault between 20. A project called the San Andreas Fault Observatory at Depth (SAFOD) near Parkfield, Monterey County, involved drilling through the fault during 2004–2007 to collect material and make physical and chemical observations to better understand fault behavior. In 1953, geologist Thomas Dibblee concluded that hundreds of miles of lateral movement could occur along the fault. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extended all the way into southern California. However, according to some of his reports from 18, Lawson actually named it after the surrounding San Andreas Valley. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. The fault was identified in 1895 by Professor Andrew Lawson of UC Berkeley, who discovered the northern zone. The slip rate along the fault ranges from 20 to 35 mm (0.79 to 1.38 in)/yr. The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. The jail where he was held still stands and is a part of the Calaveras County Historical Museum Complex.Plaque showing location of San Andreas Fault in San Mateo County
His trial was held in the court room in San Andreas and he was sentenced to six years in San Quentin Prison. He was arrested and brought back to San Andreas where he confessed to the robbery. Bolton one of the city's leading citizens. One of which was a handkerchief with a laundry mark traced back to a San Francisco Laundry where the mark was identified as belonging to C.E. Black Bart held up the Milton-Sonora stage at Funk Hill on November 3, 1883, leaving several articles behind in his hurried flight.
Handsome and debonair, Black Bart was a gentleman bandit who never harmed drivers or passengers and left bits of original verse behind signed "P08". Two infamous names from the Gold Rush often tied to San Andreas, are Black Bart and Joaquin Murieta. The channels were producing gold, although lack of water hampered the efforts of the miners until the miner's ditches were completed. In 1859 over $500,000 in gold dust was shipped. In August 1852 the large San Andreas Nugget was found in a claim just north of where the town is located and sold to the Wells Fargo company for $12,000. Andrew (San Andreas) and the name of the town was taken from this church. The first church, built in 1852 was a canvas structure with a simple cross over the door designating it a church of the Roman Catholic faith. By 1850 over 1000 tents dotted the hillsides. San Andreas was settled by Mexican Gold Miners in 1848.
