What damage can occur from an earthquake at the San Andreas fault system?

USGS scenarios project more than 1,800 deaths, and 50,000 injuries due to a major Southern San Andreas fault earthquake. CoreLogic, a business analysis service, estimated a Southern San Andreas fault rupture will cause 3.5 million homes to be at risk with $289 billion in reconstruction value.

What would happen if the San Andreas Fault ruptured?

Narrator: Parts of the San Andreas Fault intersect with 39 gas and oil pipelines. This could rupture high-pressure gas lines, releasing gas into the air and igniting potentially deadly explosions. Stewart: So, if you have natural-gas lines that rupture, that’s how you can get fire and explosions.

What is the recurrence interval of major earthquakes along the San Andreas Fault?

Studies of this section of the fault suggest an average recurrence interval of 200-300 years.

What is predicted to occur at the San Andreas Fault?

THE Big One is the name of an earthquake expected to strike along the southern San Andreas Fault in California in the coming years, and is predicted to be of magnitude 8.0 or greater.

What type of fault is San Andreas Fault?

strike-slip fault – a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral fault.

What caused San Andreas Fault?

Scientists have learned that the Earth’s crust is fractured into a series of “plates” that have been moving very slowly over the Earth’s surface for millions of years. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault.

How often does the San Andreas Fault have an earthquake?

Seismologists discovered that the San Andreas Fault near Parkfield in central California consistently produces a magnitude 6.0 earthquake approximately once every 22 years.

What is the San Andreas Fault an example of?

What type of fault is the San Andreas Fault?

Where is San Andreas fault line?

The San Andreas Fault System, which crosses California from the Salton Sea in the south to Cape Mendocino in the north, is the boundary between the Pacific Plate (that includes the Pacific Ocean) and North American Plate (that includes North America).

Where is the San Andreas Fault line?

What is the San Andreas Fault What type of plate boundary is it?

Tectonic Plate Boundaries The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.

What is the largest displacement on the San Andreas Fault?

The greatest surface displacement was 17 feet of right-lateral strike-slip in the 1940 earthquake. Clearly, this fault is part of the San Andreas system. Other earthquakes of probable magnitudes of 7 or larger occurred on the Hayward fault in 1836 and 1868 and on the San Andreas fault in 1838.

How often do earthquakes occur on the San Andreas Fault?

Geologic studies show that over the past 1,400 to 1,500 years large earthquakes have occurred at about 150-year intervals on the southern San Andreas fault. As the last large earthquake on the southern San Andreas occurred in 1857, that section of the fault is considered a likely location for an earthquake within the next few decades.

How likely is it that an earthquake will occur in San Francisco?

60\% that an earthquake measuring magnitude 6.7 will occur in the Los Angeles region. will occur in the San Francisco region. How do I get earthquake hazard maps for locations outside of the U.S.?

Is Southern California overdue for a major earthquake?

Vidale: We haven’t had a big earthquake in Southern California really since 1857. Narrator: In other words, we’re overdue for a major shake. According to a 2008 federal report, the most likely scenario is a 7.8 magnitude quake that would rupture a 200-mile stretch along the southernmost part of the fault.
