convergent. San Francisco Bay Area Earthquakes: The Hayward and San Andreas Faults are probably the most studied earthquake faults in the world, so a lot is known about them. It suggests that either the fault is creeping there, or there has been recent seismic slip.” In fact, according to Watt et al., even the most recent prehistoric earthquakes along the Rodgers Creek fault and Hayward faults, which struck sometime between 1715 and 1776, could have been a single combined event given dating uncertainties. According to experts, this fault causes a major earthquake, on average, approximately every 140 years. Most faults produce repeated displacements over geologic NCGS Commemorates the 1906 Great Earthquake by Walking…the Hayward Fault! Think: Have any Mw 9 quakes occurred on any other type of plate boundary? Strong shaking and fault rupture can also lead to many other problems, including landsliding, liquefaction, fires, disrupted transportation routes, broken water and gas pipes, downed electrical and phone lines, and many other dangerous conditions. The Hayward Fault is a major earthquake fault that runs for nearly 45 miles (72 km) through the East Bay of the San Francisco Bay region. What is likely to be the effect on the East Bay when it ruptures? This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Contributed by Dale Smith Photos by Phil Garbutt. This means that it shows its everyday action in the form of aseismic creep, the slow, steady sliding of land along the fault’s margin. It is a right-lateral strike-slip fault, meaning that motion along it is mainly horizontal, so that objects on the opposite side of the fault from the viewer will move to … ...

The cracking of the ground along the Hayward Fault was traced about 20 miles (32 km) from San Leandro to Warm Springs in Fremont, although modeling of survey data suggest that the fault moved as far north as Berkeley, and from these data the average amount of horizontal movement along the fault is inferred to be about 6 feet (1.9 meters). This creates an uplift of the East Bay hills in the Fremont area exposing the rocks of the Briones Formation, which is a fossilerous rock made of marine shells. ... the site’s distance from the fault, and the type of geologic material at the site. A fault is a fracture or zone of fractures between two blocks of rock. Copyright © 2020 KGO-TV. It is among the most active faults and seismologists warn it will likely be the source of the next "big one" in San Francisco-Bay Area. The most obvious hazard is that of large earthquakes, which induce ground shaking over a large area that can cause heavy objects to fall and windows to shatter, and can cause structural damage to buildings and bridges. Think: Have any Mw 9 quakes occurred on any other type of plate boundary? October 21, 2008, marks the 140th Anniversary of the 1868 approximate Magnitude 7 … Locate the Hayward fault. This fault is about 74 mi (119 km) long, situated mainly along the western base of the hills on the east side of San Francisco Bay. On April 15, 2006, Drs. A new report from the USGS says the biggest danger may be the Hayward Fault, because 2 million people live directly on top of it, including the cities of Oakland and Berkeley. The northern segment of the Hayward Fault stretches between San Pablo Bay and southern Oakland, and if that segment alone should break, then … What if...A 7.0 earthquake hit the San Francisco Bay Area? Damage in San Francisco from the 1989 Loma Prieta earthquake. The last major earthquake on the Hayward Fault, with magnitude 6.5-7.0, occurred on October 21, 1868. This movement causes stress, which results in earthquakes. Technically speaking, the Hayward is a right-lateral strike-slip fault. Between the San Andreas Fault and the Calaveras Fault lies the Hayward Fault, which diverges from the Calaveras Fault east of San Jose, California. The Hayward Fault has ruptured about every 140 years for its previous five large earthquakes. The Hayward Fault splinters from the Calaveras Fault, which itself is an offshoot of the The Hayward fault threatens a lot of people and structures as it runs straight through the East Bay. Picture via USGS. The largest earthquakes recorded on the San Andreas fault include the 1906 San Francisco earthquake (approximately magnitude 7.8) and the 1989 Loma Prieta earthquake … In order to better understand mechanisms of active faults, we studied relationships between fault behavior and rock units along the Hayward fault using a three-dimensional geologic map. It is located within its central section, between the latitudes of San Jose and Bakersfield.
