A fault zone which runs 70 miles along the coast of Los Angeles has the potential to trigger an earthquake with a magnitude as strong as 7.8, according to a study.

Scientists say that the Palos Verdes fault zone, which runs deep beneath the Palos Verdes Peninsula, could produce a quake as big as the more famous San Andreas Fault.
