Remember that each step in magnitude represents 32x increase in the amount of energy released in an earthquake. How much more energy was released in the Chile earthquake than the Haiti earthquake? Hint: think about how much.more energy is released in a M9 than an M7 and use that to estimate which of the following answers is correct.
