How far from a fault line is safe?
But first, what is considered a safe distance from a fault line? PhiVolcs recommends avoiding construction within five meters on each side of a fault trace. This is equivalent to a total width of 10 meters. This is considered the ideal “10-meter wide no-build zone” in the vicinity of a fault.
Why do earthquakes shake California?
The earthquakes of California are caused by the movement of huge blocks of the earth’s crust– the Pacific and North American plates. The Pacific plate is moving northwest, scraping horizontally past North America at a rate of about 50 millimeters (2 inches) per year.
Is Sacramento prone to earthquakes?

What will happen when San Andreas Fault breaks?
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.
Is Seattle on the San Andreas Fault?
The fault, also called the Seattle Fault Zone, is actually several faults in one.
