Hikermor ... thanks for posting. very interesting info. See the Wikipedia article about the 2016 quake in Kaikoura, New Zealand.

Personally, i think the calculations of quake probabilities are wrong ... on the low side. I would estimate that the chances for a major quake in the LA region in the next 5-10 years are 75%. And for the San Andreas, 95% in the next 25-30 years.

Geologists cant measure the energy stored in the Earth, before a quake happens. I think that is the missing factor. This is not a criticism of the scientists ... people cant measure what they cant see.
