An earthquake of magnitude 8.0 releases how much more energy than an earthquake of magnitude 6.0?
The Richter and Moment Magnitude scales are logarithmic. Each increase of one magnitude releases about 32 times more energy. From magnitude 6.0 to 8.0 is a two-step increase, so the energy released is 32 × 32 = 1,024 times more. ANSWER: (C) 1,024 times
