Choose the Interactive Fault Map, or download KML files and GIS shapefiles from the links on the page.California's Earthquake History. Although earlier earthquakes have been documented —such as significant movement on the southern San Andreas fault all the way back to the 1600s—the earliest reported earthquake in California was on July 28, 1769, noted by members of a Spanish expedition to chart a land route from San Diego to Monterey.The 50 km (31 mi) long Hat Creek fault, located along the western margin of the Modoc Plateau in northern California, is a geometrically complex segmented normal fault that offsets Pleistocene lavas by at least 570 m (1870 ft) of cumulative throw.The Hayward fault in California's San Francisco Bay area produces large earthquakes, with the last occurring in 1868. We examine how physics-based dynamic rupture modeling can be used to numerically simulate large earthquakes on not only the Hayward fault, but also its connected companions to the north and south, the Rodgers Creek and Calaveras faults.The offshore Cascadia fault, stretching from Northern California to beyond Vancouver Island, is capable of generating an earthquake of the same magnitude as Tohoku. But for Seattle, a potentially more dangerous fault lurks right below our feet. The Seattle Fault runs east-west just south of downtown, yet we did not know our city straddled an ...In addition to the 1906 rupture of the San Andreas fault in northern California, the San Andreas fault in south-central California also experienced a similar size earthquake in 1857, rupturing the San Andreas fault from Parkfield to just northwest of San Bernardino.

The tectonic plates are always slowly moving, but they get stuck at their edges due to friction, the USGS ... At the San Andreas Fault in California, the North Am 1. Introduction [2] The Eastern California Shear Zone (ECSZ) is a tectonically active region of the Basin and Range province located to the east of the San Andreas Fault System (SAFS) ().While the SAFS marks the major boundary between the Pacific and North American plates, roughly 20-25% of plate boundary motion is manifested by faults of the ECSZ [Dokka and Travis, 1990; Bennett et al ... Residents throughout California are on edge after two massiv

For faults in California and the rest of the United States (as well as the latest earthquakes) use the Latest Earthquakes Map: click on the "Basemaps and Overlays" icon in the upper right corner of the map. check the box for "U.S. Faults". mouse-over each fault to get a pop-up window with the name of the fault.The Northridge earthquake in Los Angeles in 1994, with a 6.7 magnitude, killed more than 70 people and led to $20 billion in damage. It was caused by one of the many faults that make up the ...Apr 21, 2021 · Hundreds of active faults run through California. With hundreds of known faults running through the state, California is no stranger to earthquakes. In fact, one occurs about every three minutes, though the majority of these are too small to be felt. But even with all this seismic activity, the state’s three major fault lines have remained ...
