Blind Thrust Fault Animation. strike-slip fault - a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral … WebFocal mechanism. The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault -related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of ...
WebOct 15, 2024 · A fault is a rupture in the Earth's crust. A reverse fault is one in which one side of the fault, the hanging wall, moves up and over the other side, the foot wall. This movement is caused by ... WebStrike-slip faults are either right-lateral or left-lateral. To determine what type you've got, figure out which way a particular object, say a road or a fence, was offset by the fault motion. If you have to go to your right to make the connection, you have a right-lateral fault. If it requires a jog to the left, it was a left-lateral fault ...
