Unexplained rock-melting forces buried deep underground cause powerful quakes along infamous San Andreas fault – RT

Experts in earthquake physics took a bottom-up approach to figuring out the cause of tremors along the infamous continental fault that runs through the Golden State. Along a particularly troublesome section of the fault they found that excitations buried much deeper than where quakes are typically monitored were the cause of major instabilities that provoke earthquakes.
“Most of California seismicity originates from the first 10 miles of the crust, but some tremors on the San Andreas Fault take…
