The strength, W, of the seismic waves of an earthquake are compared to the strength, W0, of the seismic waves of a standard earthquake. The Richter scale rating, M is given by the following equation: M = log(W/W0)

How many times more powerful are the seismic waves of an earthquake that rates 8.6 on the Richter scale than standard seismic waves?
