How was the Richter scale for measuring earthquakes developed?
The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). The original formula is: M L = log 10 A − log 10 A 0 ( δ ) = log 10 [ A / A 0 ( δ ) ] , {\displaystyle M_{\m… The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake).
