Could LA's Big One be even bigger than we thought? Now explosive helium is leaking from massive earthquake fault under Los Angeles

A huge fault in the Earth's crust near Los Angeles is leaking helium, researchers have found. They say the unexpected find sheds new light on the Newport-Inglewood Fault Zone in the Los Angeles Basin. It reveals the fault is far deeper than previously thought, and a quake would be far more devastating.
