The Richter scale measures the intensity, or magnitude, of an earthquake. The formula for the magnitude R of an earthquake is R=log((a)/(T)) B, where a is the amplitude in micrometers of the vertical motion of the ground at the recording station, T is the number of seconds between successive seismic waves, and B is an adjustment factor that takes into account the weakening of the seismic wave as the distance increases from the epicenter of the earthquake. Use the Richter scale formula to find th
