The Sawtooth Fault, which runs approximately 40 miles across central Idaho, is an old fault system that, until recently, ... [extensional] fault to have caused the event.

On extensional faults, crust extends horizontally. Landmasses slip past each other along strike-slip faults. On thrust faults, landmasses move over and under the other.

The rupture occurred along an extensional or “pull-apart” fault in the middle of the plate. Such large extensional faulting near a subduction zone is rare, and this is the third largest such event ...

Extensional faults are in fact common around subduction zones--but only in oceanic plates, not the overriding continental ones, where this one was found. How did it get there?

New Jersey experienced a 4.8 magnitude earthquake, according to the U.S. Geological Survey. Here is the science behind the cause and the Ramapo Fault.
