This problem uses the Richter scale for the strength of an earthquake. 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 M=log (W/W0) In 2013 the Khash earthquake in Iran had a Richter scale rating of 7.8.1 How many times more powerful were the seismic waves of the Khash earthquake than standard seismic waves? Round your answer to the nearest integer.
