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 …

How Do Seismic Event Sizes Scale in the Microseismic Range?
WebApr 29, 2013 · A general seismic moment tensor is decomposed and parametrized in parallel to what is done for the potency. The relations between parameters of the potency … WebApr 6, 2024 · Seismic potency has been determined based on the likelihood of an earthquake occurring in several decades or a hundred years. The seismicity rate model is developed based on the integrated data of pre-seismic shallow crustal movement data and the shallow crustal earthquake catalog data. Furthermore, the AIC is calculated based on … WebSep 2, 2016 · In addition to quantifying the size of earthquakes, the seismic potency/moment is also important for deriving many other source properties including stress/strain drop and radiated seismic energy (e.g. Aki & Richards 2002; Prieto et al. 2004 ). exteris bayer
