The hayward fault

The USGS warns that should an earthquake strike at one of the closer fault areas, such as the Hayward fault, shaking in local cities can be expected to be 5 to 12 times stronger than it was in Therefore, there is an ongoing need for all communities to continue preparing for the quakes that will strike in the future. Such an earthquake is most likely to occur on one of seven main fault systems. This would have disastrous effects on our local and regional economies.

The hayward fault

Home Index Hayward Fault Fact Sheet Page Image Page Content The Hayward Fault is considered one of the most dangerous in the world because scientists believe it is due for a large earthquake and because it runs under a densely populated area of California.

Where is the fault? The fault runs parallel to and east of the San Andreas Fault. The earthquake The three decades mentioned earlier may be an optimistic time span. That means the Hayward Fault may be due. The biggest earthquake on the fault in recorded history was an estimated magnitude 7 at 7: The fault moved northward from the Warm Springs area of Fremont possibly as far as Berkeley.

The maximum horizontal displacement was about six feet. Cracks appeared in walls as far away as Napa, Santa Rosa, and Hollister. Thirty people perished in the quake, including five in San Francisco.

Other quakes of note Earthquakes estimated at magnitude 5. In Octobera magnitude 5. It caused minimal damage. Much of the damage would be uninsured. And that figure does not include potential post-quake fire losses, damage to infrastructure, or the disruption of business.

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. A sizable earthquake could cut off water supplies — not only for drinking, but also for fighting fires -- to nearly half the Bay Area.

The aforementioned CGS scenario noted that eight large 99 beds or more acute care hospitals in Alameda and Contra Costa counties are within a mile of the fault. More than a thousand roads including the trans-bay bridges could be closed for significant amounts of time.

Liquefaction could render local airports and port facilities useless. Secondary hazards such as landslides and wildfires are possible. How large an earthquake can the fault produce? The Hayward Fault is thought capable of generating a magnitude 7.The worst scenario for the next earthquake in the San Francisco Bay Area is not from the San Andreas Fault, experts say, but from the Hayward Fault.

On its website, the USGS calls the Hayward fault the region’s “tectonic time bomb,” which could “cause hundreds of deaths, leave thousands homeless and devastate the region’s economy.”In , David Schwartz, a USGS geologist, said in an interview that above the Hayward fault are “2 million people who directly live on top of it.

It sits geographically in the center of the Bay Area. The Hayward Fault is considered one of the most dangerous in the world because scientists believe it is due for a large earthquake and because it runs under a densely populated area of California.
