Watch to find out how close you are to the most dangerous fault in America. The Hayward fault runs through the East Bay hills from Richmond to San Jose. 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. 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. Geologists have figured out the regular history of these quakes by carbon dating trenches along the fault. On October 21, 1868, a magnitude 6.8 earthquake struck the San Francisco Bay region. The Hayward fault, a major branch of the right-lateral San Andreas fault system, traverses the densely populated eastern San Francisco Bay region, California. 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. 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. To start the tour, download and open the “Hayward Fault Map and Tour” file in Google Earth (free download), then click the “Play Tour” button located at the bottom of the “Places” panel. Severe earthquakes were generated by this fault zone in 1836 and in 1868, and several large earthquakes have been recorded since 1868. On April 18th of this year, the HayWired earthquake scenario will be released to the public. The Hayward Fault. The paleoearthquake histories for nearby faults of the San Francisco Bay region appear to indicate less regular and frequent earthquakes, possibly because most lack the high proportion (40-60%) of aseismic release found on the Hayward fault. The Hayward Fault is an offset of the San Andreas Fault system that dominates the landforms of eastern San Francisco Bay. 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. The Hayward Fault Zone derived its name from the city of Hayward in the San Francisco Bay Area. The relative motion between the North American Plate (southeast) and the Pacific Plate (northwest) create stress that releases energy as earthquakes. Our goal is to create a safe and engaging place for users to connect over interests and passions. The Hayward Fault, which runs along the eastern side of San Francisco Bay, is among the most active and dangerous in the United States, because it passes through our … It extends approximately 50 miles along the foot of the East Bay hills, from south Fremont into the San Pablo Bay. Please take some time to prepare yourself and your family in the unfortunate event of the 'Big One'. 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… The Hayward Fault runs 40 miles, from San Pablo Bay to Fremont, through some of the most densely populated areas in the country. The Hayward fault is due for another large earthquake very soon. We’ve updated this video: https://youtu.be/GhFMtCmHc9cOctober 21st will mark the 141st Anniversary of the 1868 Hayward Earthquake. To start the tour, download and open the “Hayward Fault Map and Tour” file in Google Earth (free download), then click the “Play Tour” button located at the bottom of the “Places” panel. The relative motion between the North American Plate (southeast) and the Pacific Plate (northwest) create stress that releases energy as earthquakes. 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). The Hayward fault under Oakland is more dangerous than the well-known San Andreas fault in Southern California, according to a new study that says it has the potential to kill at least 800 people and injure 18,000 more, The Los Angeles Times reported. The Hayward fault under Oakland is more dangerous than the well-known San Andreas fault in Southern California, according to a new study that says it has the potential to kill at least 800 people and injure 18,000 more, The Los Angeles Times reported. The results show that an earthquake of that scale could kill up to 800 people and cause more than $100 billion in total damage. 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. 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. More than 2.4 million people live on or close to the Hayward Fault. The Hayward Fault is the single most urbanized earthquake fault in the United States—in 1868 there were only 24,000 residents living in Alameda County; now there are more than 2.4 million people.
