The Japan Meteorological Company seismic depth scale, the Medvedev–Sponheuer–Karnik scale, plus the Mercalli depth scale are dependant on the noticed outcomes.

Reverse faults take place in spots in which the crust is go to this site staying shortened like in a convergent boundary. Strike-slip faults are steep buildings in which the two sides of your fault slip horizontally past one another; completely transform boundaries are a certain style of strike-slip fault.
