A recent study found such an event would cause an estimated 800 deaths, 18,000 injuries and billions in damage. Scientists have been studying the past earthquakes on the Hayward fault. Earthquake Science Zones: There will be two sites that people could ask scientists and educators about the science behind the Hayward Fault. A new study examines series of small earthquakes occurring near the Dallas/Fort Worth International Airport between Oct. 30, 2008, and May 16, 2009. and that much life-safety protective work remains to be done. 0000574351 00000 n A shaking simulation for the San Francisco Bay Area for a magnitude 7.0 earthquake on the Hayward Fault.

The Hayward Fault in Fremont creeps about 3/16ths of an inch (5mm) per year. Its last major rupture occurred in 1868, during California's frontier days, and was the original "Great San Francisco Earthquake" until 1906.. The largest of the DFW-area earthquakes was a 3.3 magnitude event reported by the USGS National Earthquake Information Center. 0000092139 00000 n Of all of these faults, the Hayward Fault has the highest probability of rupturing in a M=6.7+ earthquake in the next 30 years, according to the USGS. x�b``�e``+a``�ؓʀ The Hayward fault runs through the East Bay hills from Richmond to San Jose. 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 … It was considered the "Great Earthquake" until 1906. 0000432059 00000 n Of all of these faults, the Hayward Fault has the highest probability of rupturing in a M=6.7+ earthquake in the next 30 years, according to the USGS. 0000077224 00000 n 0000487440 00000 n … The fault needs to move about 6/16ths of an inch (9mm) per year to release the energy building up at the surface. Hayward was ranked as the 32nd most populous municipality in California. There are roughly 30,000 miles of faults cutting across California, but the three fault sections that most concern many seismologists are the San Andreas, San Jacinto and Hayward.

A 7.0 earthquake would be … The earthquake will cause $90.4 billion damage to residential buildings and 96.4 to commercial buildings. They have found that the most recent 5 major earthquakes happened on average every 140 years. The “Shake Map” at right shows the shaking intensities expected for a hypothetical scenario earthquake (magnitude 6.7) on the southern Hayward Fault, which last ruptured in 1868 in an event of magnitude about 6.9.
However, as in 1906, well-constructed buildings on firm ground sustained much less damage.Towns in the East Bay suffered the most severe damage. 0000052876 00000 n When the last quake struck the Hayward Fault in 1868, the Bay Area was sparsely populated. Hayward Fault Shake Map. Take a virtual tour with Google Earth to explore what the East Bay looked like in 1868 and what the damage was like. 0000073986 00000 n 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. It runs through densely populated areas, including Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Castro Valley, Hayward, Union City, Fremont, and San Jose. 0000061761 00000 n The “Shake Map” at right shows the shaking intensities expected for a hypothetical scenario earthquake (magnitude 6.7) on the southern Hayward Fault, which last ruptured in 1868 in an event of magnitude about 6.9. Running for nearly 74 miles through cities including Fremont, Hayward, Oakland, Berkeley, and Richmond, the Hayward Fault has the potential to wreak more havoc than most California faults. 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 landslides or liquefaction—exist near you. 0000565858 00000 n State of California. <<8017d3c2c394e94f98a43e41337707f7>]>> Dr. Sue Ellen Hirschfeld, previously a Professor of Geology at California State University, East Bay, has an informative website with lots of photos and interesting places to visit. According to the USGS, the real threat comes from smaller (about magnitude 7) earthquakes occurring on the Hayward fault, the Peninsula segment of the San Andreas fault, or the Rodgers Creek fault. On Monday evening (May 14), there was a 3.5 magnitude earthquake along the fault centered just east of Oakland. 0000003146 00000 n However, many scientists believe that the Hayward Fault is connected to the Calaveras Fault to the south, the Rodgers Creek Fault to the north and to the Maacama Fault still farther north.

The newer map on the left shows an earthquake fault zone as a semi-transparent yellow polygon. This is an easy walk and a good opportunity to educate yourself and your children. 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. Luke Blair and Susan Garcia (both from the U.S. Geological Survey showcased the "Faulted Floor" where 60 years of "creep" along the Hayward Fault can be seen. For residents of the San Francisco East Bay, the greatest seismic hazard is the Hayward Fault. The few remaining Native Americans in the area spoke of the earth shaking and ocean rising to consume the land. 6 0 obj<> endobj Along with great virtual tours, the USGS has many wonderful sets of maps of the Bay Area that show different aspects of living in such a tectonically active area. But the most significant improvement in shaking resistance was the advent of steel-frame buildings in 1885. 0000027984 00000 n A shaking intensity map for the 1868 Hayward fault earthquake. These large earthquakes were both regular and frequent, as indicated by a 0.40 coefficient of variation and mean recurrence interval (MRI) of 161 ± 65 yr (1σ of recurrence intervals). By the time Lewis and Clark arrived on the West Coast in 1805, it had been 105 years since the Cascadia Subduction Zone last ruptured, sending a large portion of the Pacific Ocean roaring toward the coast. The Hayward fault is a 90 kilometer long crack in the Earth's crust that travels through the San Francisco Bay area. 0000302810 00000 n The Hayward Fault runs through the East Bay from San Pablo Bay in … On Monday evening (May 14), there was a 3.5 magnitude earthquake along the fault centered just east of Oakland. For residents of the San Francisco East Bay, the greatest seismic hazard is the Hayward Fault. 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. event of an earthquake of magnitude 6.9 on the Hayward fault As is apparent, the most intense (MMI Vlll+) zone would be primarily within the borders of Alameda County.
