NASA: 99.9% LA Quake

NASA JPL says there's a 99.9% certainty the 'big one' slams Los Angeles between now and the end of 2017.

JPL geophysicist Dr Andrea Donnellan says, “There’s enough energy stored to produce about a magnitude 6.1 to 6.3 earthquake.”

A quake that big with an epicenter near downtown LA will destroy most of the city.

But Robert Graves, a US Geological Survey (USGL) seismologist says not so fast.

Graves insists, “The 99.9% number – I don’t know the method that was used to derive that. But basically, that's saying that’s going to happen...and that level of certainty, to my knowledge, is just not attainable. We can never be that certain.”
