The moment magnitude scale denoted Mw is a scale that measures the energy released by an earthquake and is now preferred 2 log M 10 7 where Mo is the magnitude of 3 over the Richter scale for medium to large earthquakes The formula Mw the seismic moment or the energy released in dyne centimeters An earthquake in 1964 in Alaska had a moment of 7 5X102 dyn cm Compute the moment magnitude for this earthquake Round your answer to the nearest tenth Source USGS
