Is San Andres a normal fault?
The San Andreas Fault—made infamous by the 1906 San Francisco earthquake—is a strike-slip fault. This means two fault blocks are moving past each other horizontally. Strike-slip faults tend to occur along the boundaries of plates that are sliding past each other.
What happens if the San Andreas Fault slips?
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.
