It's a Other size geocache, with difficulty of 2, terrain of 1. A fault’s length is related to the maximum strength of an earthquake it can produce. The map volume is 100 km long, 20 km wide, and extends to a depth of 12 km below sea level. The Hayward fault is a 90 kilometer long crack in the Earth's crust that travels through the San Francisco Bay area. It runs through densely populated areas, including Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Hayward, Union City, Fremont, and San Jose. 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. Real estate disclosure is required when property within a zone is sold. By digging trenches across the fault, scientists have determined that the last five earthquakes large enough to cause damage have occurred about every 140 years (the “recurrence rate”). If that is the case, the longer fault system could produce larger temblors. Wentworth Abstract A three-dimensional (3D) geologic map of the Hayward Fault zone was created by integrating the results from geologic mapping, potential field geophysics, and seismology … (Play Video), Cooperative Institute for Deep Earth Research (CIDER), Northern California Earthquake Data Center (NCEDC). They have found that the most recent 5 major earthquakes happened on average every 140 years. Tap to unmute. T he Hayward Fault is within the San Andreas Fault Boundary Zone between the North American Plate and the Pacific Plate. It is a member of the San Andreas Fault system that runs from the Gulf of California in the south, to Cape Mendocino in the north. Aside from size and reputation, a major difference between the Hayward and San Andreas faults is “aseismic creep”. The map volume is oriented northwest and is approximately bisected by the Hayward Fault. The Hayward Fault could unleash a magnitude 7.0 earthquake, capable of catastrophic damage. 1202 x 758 png 567kB. Hayward Lake, a lake and reservoir on the Stave River, British Columbia; New Zealand. The Hayward Fault, a ... What scientists can do right now is make good maps of fault zones and figure out which ones are probably due for a rupture. model predicted that we’d have the greatest subsidence. Evidence of creep can be found from Pt. Hayward, California, a city in Alameda County California State University, East Bay, formerly named California State University, Hayward; Hayward (BART station), Bay Area Rapid Transit station; Hayward Executive Airport; Hayward Fault Zone, earthquake fault running through Hayward; South Hayward (BART station), transit station The fault runs parallel to and east of the San Andreas Fault. 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. The San Andreas Fault system forms the boundary between the North American and the Pacific tectonic plates. We believe this depression is indicative of the formation. With an estimated magnitude of 6.8 it caused damage throughout the area. Two CGS programs establish regulatory zones in seismically active areas to protect lives and property. The Hayward fault is one of only a few dozen faults in the world that “creeps,” or slowly moves. This zone follows the Hayward Fault along its northern half and then diverges from it to the east near San Leandro, forming the Mission trend. Hi there! The Hayward Fault: Predictable Peril | KQED QUEST - YouTube. Jachens, D.A. THREE-DIMENSIONAL GEOLOGIC MAP OF THE HAYWARD FAULT ZONE, SAN FRANCISCO BAY REGION, CALIFORNIABy G.A. What if...A 7.0 earthquake hit the San Francisco Bay Area? This slip slide motion is called a transform fault. As described in this report, the Hayward fault zone is a zone of highly deformed rocks which trends north 30 degrees west from an area southeast of San Jose to the San Pablo Bay, and ranges in width from 2 to 10 kilometers. Estimated moment magnitude of 6.3–6.7 and a maximum Mercalli intensity of IX , it was the most recent large earthquake to occur on the Hayward Fault Zone. The Seismic Hazard Mapping Program addresses the secondary earthquake hazards of liquefaction (the inability of water-saturated, heavily shaken soil to support structures) and landslides. We observe fault zone head waves (FZHW) that are generated by and propagate along a roughly 80 km section of the Hayward fault in the San Francisco Bay area. And they can make forecasts. The Alquist-Priolo program is designed to ensure that structures for human habitation are not built atop surface traces of active faults (in most cases, a 50-foot setback is required). It extends from San Jose about 74 miles northward along the base of the East Bay Hills to San Pablo Bay. A sizable earthquake could cut off water supplies – not only for drinking, but also for fighting fires -- to nearly half the Bay Area. It was considered the "Great Earthquake" until 1906. The Hayward fault belongs to the San Andreas system that separates the Pacific plate and the Sierra Nevada microplate, accommodating 75-80% (38–40 mm/year) of the present relative motion between Pacific and North American plates (e.g., Argus & Gordon, 2001, Wakabayashi Thirty people perished in the quake, including five in San Francisco. Key words: Fault zone head waves, Hayward fault, Bimate-rial interface, Seismic imaging of faults, Moveout analysis, Particle motion analysis. The Hayward Fault Zone is a geologic fault zone capable of generating significantly destructive earthquakes. We do not see this depression in the southern half of the bay. Hayward (profession), officer of a township in charge of fences and enclosures Hayward (surname) Hayward (given name) Places Canada. At a time when the greater Bay Area had a population of only about a quarter-million and infrastructure was minimal, damage was estimated at $350,000 in 1868 dollars. pubs.usgs.gov. HAYWARD — An observant engineer who spotted an irregularity in the soil at a housing development site more than 10 years ago led to the discovery of a new fault in the Hayward fault earthquake zone. That report stated that there’s a 31 percent chance the Hayward Fault will produce a magnitude 6.7 or greater earthquake in the next three decades. There are 12 Alquist-Priolo zone maps covering the Hayward Fault. Cracks appeared in walls as far away as Napa, Santa Rosa, and Hollister. The HCFZ considered here encompasses the HF, the northern CF, and the central CF from the junction with the northern CF to Gilroy (Figure 1). Its last major rupture occurred in 1868, during California's frontier days, and was the original "Great San Francisco Earthquake" until 1906.. A lidar image of the east side of UC Berkeley and the Hayward fault (red). Potentially active fault, in Santa Clara County, California. of the Hayward fault, including a statistically preferred propagation direction of earthquake ruptures to the SE. 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. 300 x 401 jpeg 57kB. While a significant amount of structural retrofitting work has been done in the Bay Area, the Hayward Fault runs under numerous lifelines, such as freeways, the Hetch Hetchy Aqueduct, and Bay Area Rapid Transit tracks. The HCFZ considered here encompasses the HF, the northern CF, and the central CF from the junction with the northern CF to Gilroy (Figure 1). near-vertical fault zone at most locations. The fault is around 119 km long and offers the potential for generating very destructive earthquakes.
