Chapter 1, Problem 33P
The Moment Magnitude Scale (MMS), denoted Mw, which measures the total energy released by an earthquake, is given by:
where M0is the magnitude of the seismic moment in dyne-cm (measure of the energy released during an earthquake). Determine how many times more energy was released from the largest earthquake in the world, in Chile (MW= 8.7), 1960, than the earthquake in Rat Island, Alaska (MW= 8.7), in 1965.
