Seismic potency

Seismic moment is a quantity used by seismologists to measure the size of an earthquake. The scalar seismic moment is defined by the equation , where • is the shear modulus of the rocks involved in the earthquake (in pascals (Pa), i.e. newtons per square meter) • is the area of the rupture along the geologic fault where the earthquake occurred (in square meters), and WebAug 1, 2024 · Similar to apparent stress, apparent volume depends on seismic potency and radiated energy, and because of its scalar nature, it can easily be manipulated in the form …
