What caused the San Andreas Fault?
Two of these moving plates meet in western California; the boundary between them is the San Andreas fault. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault.
What kind of fault is San Andreas Fault?
strike-slip 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.
Where can I see the San Andreas Fault?
The San Andreas Fault begins near the Salton Sea, runs north along the San Bernardino Mountains, crosses Cajon Pass, and then runs along the San Gabriel Mountains east of Los Angeles. The mud pots near the Salton Sea are a result of its action, but your best bet to see the Southern San Andreas Fault is at Palm Springs.
How old is the San Andreas Fault?
about 28 million years old
The San Andreas fault is about 28 million years old. Back then, California didn’t exist, at least not recognizably so.
What happens if the San Andreas Fault breaks?
Death and damage About 1,800 people could die in a hypothetical 7.8 earthquake on the San Andreas fault — that’s according to a scenario published by the USGS called the ShakeOut. More than 900 people could die in fires, more than 600 in building damage or collapse, and more than 150 in transportation accidents.
What happens if the San Andreas Fault ruptures?
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.
