The Richter Scale measures the amount of energy released by an earthquake by measuring the magnitude or seismic waves produced by an earthquake. The Richter Scale measures from 0 to 9. On the scale, each increase in number represents an earthquake 10 times more powerful. At 4.5 an earthquake can damage buildings and structures. At 7 on the Richter scale, severe and catastrophic damage can occur.
