What will happen if 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.
Can San Andreas happen?
Could the San Andreas Fault open up to create the canyon we see in the movie? The movie’s gaping chasm is completely impossible. Earthquakes happen because of friction and with a gap that wide, there would be no earthquake!
