The moment magnitude scale, denoted Mw, is a scale that measures the energy released by an earthquake and is now preferred over the Richter scale for medium to large earthquakes. The formula Mw = 2/3 log(Mo) 10.7, where Mo is the magnitude of the seismic moment, or the energy released in dyne centimeters. An earthquake in 1964 in Alaska had a moment of 7.5X10^29 dyn-cm. Compute the moment magnitude for this earthquake. Round your answer to the nearest tenth. (Source: USGS) Type your numeric answer and submit
