The QFFD contains information on faults and associated folds that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). These data are compiled from thousands of journal articles, maps, theses, and other documents. The QFFD is now the best source for detailed information on faults, and is the source of ....

Brown lines are known hazardous faults and fault zones. Magnitude = ? for new earthquakes until a magnitude is determined (takes 4-5 minutes). Maps are updated within 1-5 minutes of an earthquake or once an hour. (Smaller earthquakes in southern California are added after human processing, which may take several hours.)The California Geological Survey periodically issues official maps of earthquake fault zones, in compliance with the Alquist-Priolo Earthquake Fault Zoning Act. Two examples of earthquake fault zone maps are shown in the figure below. The newer map on the left shows an earthquake fault zone as a semi-transparent yellow polygon.A fault is a break in the earth's crust along which movement can take place causing an earthquake. In Utah, movement along faults is mostly vertical; mountain blocks (for example, the Wasatch Range) move up relative to the downward movement of valley blocks (for example, the Salt Lake Valley). Faults with evidence of Holocene (about 10,000 ...

The percentage shown within each ...This map shows areas of seismic risk from high (red) to low (grayish-green). The map is from a 2007 report (click here to download) on seismic design categories in Washington. The map also shows potentially active faults from a separate 2014 report (click here to download). Earthquakes occur nearly every day in Washington. Most are too small to be felt or cause damage.San Jose Area Faults. The San Jose Area is criss-crossed by a series of major faults that together relieve the motion and grinding between the huge Pacific and North American plates. The San Andreas Fault and other Bay Area fault zones are on both sides of the bay: San Jose fault, Berrocal fault zone, Hayward fault zone, Chabot fault, San ...

A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers.Bay Region: Bulletin Seismological Society of America, v. 89, p. 764-784 and 1967-2014 earthquakes from the Northern California Seismic Network.

On maps it is usually depicted as a single continuous line reaching from the Salton Sea in the south all the way to Cape Mendocino in Northern California. Such a simple representation suggests that the fault is a homogeneous entity with the same ...The Hayward fault is an extremely interesting feature of the East Bay and you can see its footprints all over the place once you know where and how to look. There are many easy tours you can take to get a closer look at this subterranean beast, as well as maps to find out how close you live to the fault and what seismic hazards—such as ...A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried. In contrast, a fault line is where the fault cuts the Earth's surface… if indeed it does. The most prominent faults in each state are usually shown on a state's geologic map as black lines.

The Ridgecrest, California earthquake sequence sparked similar questions: Did the M6.4 earthquake on July 4, 2019 trigger the M7.1 on July 5, 2019?

This type of plausible quake might be strong adequate to trigger liquefaction in all Bay Area ...The new earthquake faults created by the Napa quake will probably appear on the next California fault line map! This updated earthquake map should educate the state about quake risk zones and help residents grasp the geography of the fault lines. Because, one thing must be known: The more scientists study quakes in California, the more faults ...
