Earthquake Fault Slip

Slip is defined as the relative movement of geological features present on either side of a fault plane, and is a displacement vector. A fault's sense of slip is defined as the relative motion of the rock on each side of the fault with respect to the other side.

The maximum fault slip displacement is proportional to ten to the power 0.82 times the seismic moment magnitude. The average fault slip displacement is proportional to ten to the power 0.69 times the seismic moment magnitude.

Formula

{QuantityVariable["MD", "Length"] == 10^(-5.46 + 0.82*QuantityVariable[Subscript["M", "w"], "Unitless"])*Quantity[1, "Meters"], QuantityVariable["AD", "Length"] == 10^(-4.8 + 0.69*QuantityVariable[Subscript["M", "w"], "Unitless"])*Quantity[1, "Meters"]}

symbol description physical quantity
MD maximum displacement "Length"
Mw seismic moment magnitude "Unitless"
AD average displacement "Length"
