Scientists studying the movements along the San Andreas fault line have discovered the potential of what they are calling "supershear" quakes. That means, the ground thrusts up so quickly that the movement precedes the shaking and even the rumble.
According to geologists, no buildings will be able to withstand the megaforce ruture of the ground which will be moving as fast as 3miles/ 5 km per second!
This matches exactly what I have been saying for years--that the subduction zone will rupture and everything on the surface will be demolished in seconds.
