Property

NameMoment Magnitude
CodeMw
SymbolM<sub>w</sub>
Description

The magnitude is computed from a long-period body- and mantle-wave moment tensor inversion method; it is also related to the product of the area of the earthquake fault, multiplied by the average fault slip over that area and by the shear modulus of the fault rocks. The Mw value is approximately the same as the Ms magnitude value.
