kilometers from the epicenter of an earthquake. Tables have been formulated to demonstrate the magnitude of any earthquake from any seismograph. For example‚ for a one-unit increase in magnitude‚ there is an increase of times thirty in released energy. To put that another way‚ each number on the Richter scale represents an earthquake ten times as strong as one of the next lower magnitude. Specifically‚ an earthquake of magnitude 6 is ten times as strong as an earthquake of magnitude 5. The
