A number of spills have previously occurred due to landslides and such spill and related toxic and flammable material release may be prevalent in a major seismic event.

The Hetch Hetchy Aqueduct, which supplies 270 to 315 million gallons of water per day to the City of San Francisco and other Bay Area communities, directly crosses the Hayward Fault in Fremont. A replacement of the eastern span was completed in August 2013. children learn critical thinking skills. It is also being subducted far to the northwest into the Aleutian Trench. living resources, natural hazards, and the environment. Normal resolution; HD resolution; Detailed Perspective Views . Similar trench excavations are used in the determination of the frequency and magnitude of prehistoric earthquakes and to determine the location of latent faults as part of the science of Paleoseismology. 40204 Paseo Padre Parkway

Also in the park is an exhibit “The Hayward Fault Exposed!” an interpretive viewing and educational exhibit sponsored by the U.S. Geological Survey, City of Fremont, Risk Management Solutions, and Swiss Reinsurance. Tule Ponds at Tyson Lagoon to Stivers Lagoon (pdf), October 21, 2018, 150th Anniversary With an estimated magnitude of 6.8 it caused damage throughout the area. The Hayward Fault If you are a resident of another country or region, please select the appropriate version of Tripadvisor for your country or region in the drop-down menu. Memorial Stadium supporting columns diverging at the top due to, Potentially impacted structures and features, Electrical and communication system disruption. [18] Earlier (January 2008) assessments suggest that the Hayward, Rodgers Creek, and Calaveras faults may be more likely to fail in the next few decades than previously thought.[2].

In June 2006 Bay Area Rapid Transit (BART) management announced that they have elected not to modify the Berkeley Hills Tunnel, which actually penetrates the Hayward Fault, arguing that it would be cheaper (and less disruptive to current operations) to rebore a misaligned portion after the fact than to protect riders (either by extensive modifications of the tunnel or by replacing it with a higher bore) against the small likelihood that a train (or two) would crash into or be cut in two by a major slippage of the fault. No serious damage was reported.

This is an easy walk and a good opportunity to educate yourself and your children. These three scenarios show the ground shaking for a magnitude 6.8 earthquake on the Hayward fault. http://usgs.gov, for more informationMath/Science Nucleus It runs through densely populated areas, including Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Castro Valley, Hayward, Union City, Fremont, and San Jose. At the lower elevations near the bay the soil is mostly water saturated mud and sand, placed in the early 20th century as fill in marsh areas. The 1989 Loma Prieta earthquake caused a failure of a single section of the upper deck of the eastern span of the San Francisco–Oakland Bay Bridge, which closed the bridge for 30 days. Only a portion of the structural deficiencies in the larger area have been addressed, and the surface motion effects of a large event are likely to be far more severe than seen in the Loma Prieta event. Children's Natural History Museum and Tule Ponds at

Subsequent seismic analysis indicated the possibility that the overfill could fail due to agitation, allowing the buoyant tube to float upward, misaligning the tracks and possibly overstressing the bolted connections. As with portions of other faults, a large extent of the Hayward Fault trace is formed from a narrow complex zone of deformation which can span hundreds of feet in width. However, the 1868 quake caused much damage throughout the then sparsely settled Bay Area, including the city of San Francisco. and that much life-safety protective work remains to be done. Tule Ponds at Tyson Lagoon and the historic Stivers Lagoon. This allows for urban features such as more. It is expected that these segments may fail singly or in adjacent pairs, creating earthquakes of varying magnitude. Science Nucleus) The detailed, perspective views show the ground shaking from a viewpoint two miles (three kilometers) above the earth looking towards each location.

The current estimates of the probability of a major earthquake on any of the numerous regional faults range up to 70 percent within the thirty-year period 2000–2029. Its fascinating. There is the possibility that a large earthquake could trigger very large earth flows, particularly if the soils are seasonally saturated with water, possibly rendering extensive areas unbuildable.

The progressively more severe reports and estimates of event probability and consequences have awakened a broad interest in training people for emergency response.

As elsewhere in the area, such structures have undergone extensive retrofitting for safety. Please credit the U.S Geological Survey. The UCERF3 represents the best available science to date, and it now considers "multifault ruptures" and "fault readiness", in addition to historical seismicity, in the calculus of earthquake forecasting.

The signs are there to be seen for those that know what to look for: rippled asphalt, misaligned curb stones, uplifted or depressed land, etc. Take a virtual tour with Google Earth to explore what the East Bay looked like in 1868 and what the damage was like. The Pacific Plate is a major section of the Earth's crust, gradually expanding by the eruption of magma along the East Pacific Rise to the southeast. It has a population of close to 1/4 million people and They do warn that all residents of the region should be prepared for a large event and its subsequent effects (e. g., lack of water, firefighting, first aid, electricity, motor and heating fuels, etc.) Tule Ponds at Tyson Lagoon to Stivers Lagoon (pdf)(2006), Fremont Earthquake It goes through the flat land starting Fremont Earthquake Exhibit: The Hayward Fault Exposed, This geotourism exhibit (April through October 2006, now closed) featured a 12- to 15-foot (5 m) deep pit exposing the Hayward Fault, which could be viewed "face to face" from a shaded platform by descending a staircase. Additional stabilization includes the driving of large pilings and the connection of additional restraints.

Significant features were noted and marked. These three scenarios show the ground shaking for a magnitude 6.8 earthquake on the Hayward fault.
