A new, decade-long study suggests that the earthquakes in the region can stop or “jump” due to interactions between the San Andreas and nearby San Jacinto fault, allowing for the strong shaking to move around the rocks and not hit them head on, BBC News reported.
The ways in which these fault lines interact may help seismologists better understand not only big tremors read more >>>
