Every 140 years for the past two thousand the Hayward Fault has jolted the East Bay. San Lorenzo Creek runs through the city. Introduction [2] The Hayward Fault is located on the eastern side of San Francisco Bay, California, and forms one branch of the San Andreas Fault system that accommodates the relative motion between the North American and Pacific plates. The chart below should give you some perspective on how much devastation this … (Credit: U.S. Geological Survey) Over the last decade, paleoseismologists (geologists who study ancient earthquakes) at the USGS have been digging trenches across the Hayward Fault, peering into tectonic time in order to find evidence of fossil earthquakes. Today, more than 2.4 million people live close to the fault and are at great risk when the next significant earthquake occurs. This slip slide motion is … 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). Since it has been more than 144 years since the last major earthquake, the clock is ticking. The Hayward Fault, a long and lethal crack in the Earth, slices along the base of the Berkeley Hills and directly through the University of California. The Hayward fault zone is considered to be the most … The Hayward Fault, a long and lethal crack in the Earth, slices along the base of the Berkeley Hills and directly through the University of California. Please take some time to prepare yourself and your family in the unfortunate event of the 'Big One'. The Hayward fault is due for another large earthquake very soon. The United States Geological Survey has stated that there is an "increasing likelihood" of a major earthquake on this fault zone, with potentially serious resulting damage. The relative motion between the North American Plate (southeast) and the Pacific Plate (northwest) create stress that releases energy as earthquakes. The Hayward Fault. The Hayward fault runs through the East Bay hills from San Jose through Richmond. San Lorenzo Creek runs through the city. The Hayward Fault Zone is a geologic fault zone capable of generating destructive earthquakes. On April 15, 2006, Drs. The Hayward Fault Zone runs through much of Hayward, including the downtown area. Watch to find out how close you are to the most dangerous fault in America. With an estimated magnitude of 6.8 it caused damage throughout the area. How Close to a Fault do You Live? In 2015, UC Berkeley researchers suggested that the Hayward fault may be connected to the nearby Calaveras fault, which, if true, would mean the potential for a more powerful quake. This fault … Copyright © 2020 UC Regents; all rights reserved, Explore the science behind a simulation of a magnitude 7 earthquake on the East Bay's Hayward Fault and learn what it could mean for shaking potential in your area. What if...A 7.0 earthquake hit the San Francisco Bay Area? The Hayward Fault is an offset of the San Andreas Fault system that dominates the landforms of eastern San Francisco Bay. It is very likely that the Hayward fault will rupture and produce a significant earthquake within the next 30 years. The USGS simulated a 7.0 magnitude earthquake on the Hayward Fault, which runs up and down the East Bay Area through Berkeley, Oakland, Hayward, Fremont and Milpitas. More than 2.4 million people live on or close to the Hayward Fault. Geologists have figured out the regular history of these quakes by carbon dating trenches along the fault. According to a new study, the Hayward fault line that runs under Oakland, California is believed to be more dangerous than the infamous San Andreas fault line that spans Southern California.. Learn more at outsmartdisaster.com. Its last major earthquake occurred on October 21st, 1868, destroying downtown Hayward, killing 5 people and, injuring 30. This fault, called a “tectonic time bomb,” is about 74 miles long. Among other sites, the fault runs directly under the now-abandoned old city hall in downtown Hayward, the University of California-Berkeley football stadium, the Mira Vista Golf Course near Berkeley, Lake Temescal, Contra Costa College, and Port Pinole Shoreline Regional Park. We conducted a paleoseismic investigation to better understand the Hayward fault's past earthquake behavior. In 2018 … The U.S. Geological Survey estimates that a quake … 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. A lidar image of the east side of UC Berkeley and the Hayward fault (red). SAN FRANCISCO (KGO) -- While the San Andreas fault gets much of the attention after the devastating 1906 and 1989 quakes, it's the Hayward fault, which runs along the East Bay… Hundreds of homes and other structures are built along the fault trace, and mass transit corridors, major freeways, and many roadways cross it at numerous locations. The Hayward Fault runs along the foot of the East Bay hills, something that all residents of the Bay Area, and the East Bay in particular, should know. On October 21, 2018, we will commemorate the 150th anniversary of the M 6.8 Hayward Fault earthquake. Severe earthquakes were generated by this fault zone in 1836 and in 1868, and several large earthquakes have been recorded since 1868. The Hayward Fault Zone derived its name from the city of Hayward in the San Francisco Bay Area. Bay Area Earthquakes: Hayward Fault Damage Will Be Devastating. This slip slide motion is … The Hayward Fault runs through much of the East Bay. The northernmost Hayward fault and Rodgers Creek fault (RCF) appear to rupture only half as frequently as the HS and are separated from the HS by a creep buffer … Like most earthquake faults in the region, it is a right-lateral strike-slip fault; that is, facing the fault from either side, the opposite side moves to the right. Bundled with the map and tour are: 1) photographs showing evidence of creep and other aspects of faulting, 2) locations of creep, 3) locations of exploratory trenches crossing the fault, 4) moving landslides (from InSAR, only available for northern Berkeley Hills), and the kilometer grid used in the published map. The Hayward fault, a major branch of the right-lateral San Andreas fault system, traverses the densely populated eastern San Francisco Bay region, California. The United States Geological Survey has stated that there is an "increasing likelihood" of a major earthquake on this fault zone, with potentially serious resulting damage.
