A 7.6 is equal to about 200 Million Tons of TNT going off.
That's equal to 400 Billion pounds of dynamite blasting.
I think that puts into into perspective.
An 8.0 is equal to 2 Trillion pounds. It goes up exponentially.
If and when the San Andreas faults blows full force seismologists estimate it could reach a yield at 10.0 magnitude which would be 2 Trillion Tons which equals 4 Quadrillion pounds of TNT going off which would be the force needed to separate California west of the fault from the North American plate completely.
