The modified mercalli intensity scale is used to measure the intensity of an earthquake and is in part derived from the damage done to building and other structures. Edit Share to:
The Richter Scale measures magnitude, the amount of energy released by an earthquake by measuring how big a shock wave is. Each number on the scale is 10 times more powerful than the number below it. A magnitude 3 earthquake is ten times greater that a magnitude 2 and is easily felt. An earthquake that registers 6 or more is considered a major quake.
