Quote:Helium is LEAKING from massive earthquake fault in LA raising fears 'big one' could be more devastating than thought

• Indicates Newport-Inglewood fault more important than previously thought
  
• Risk in the next 30 years of 'big one' increased from about 4.7% to 7.0%
  
• However, study says risk of smaller quakes has actually gone down
  

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.
