The San Gregorio Fault is an active, 209 km (130 mi) long fault located off the coast of Northern California. The southern end of the fault is in the Pacific Ocean just south of Monterey Bay , and the northern end is about 20 km northwest of San Francisco , near Bolinas Bay , where the San Gregorio intersects the San Andreas Fault .
The Maacama Fault is a right lateral-moving (dextral) geologic fault located in the Coast Ranges of northwestern California.It is considered to be the northernmost segment of the Hayward Fault subsystem of the San Andreas Fault zone.
The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. According to the United States Geological Survey, Southern California experiences nearly 10,000 earthquakes every year. [3] Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
The oldest rocks in California date back 1.8 billion years to the Proterozoic and are found in the San Gabriel Mountains, San Bernardino Mountains, and Mojave Desert.The rocks of eastern California formed a shallow continental shelf, with massive deposition of limestone during the Paleozoic, and sediments from this time are common in the Sierra Nevada, Klamath Mountains and eastern Transverse ...
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas Fault that defines the western extent of the assemblage. [1]
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
Mormon Rocks is an example geological formation along the San Andreas Fault. The Pacific plate, to the west of the fault, is moving in a northwest direction while the North American plate to the east is moving toward the southwest, but relatively southeast under the influence of plate tectonics. The rate of slippage averages about 33 to 37 ...
