WebInstructions A Richter scale nomograph or seismography display helps one estimate earthquake magnitudes from seismograph readings. Using the chart below, plot the time difference in arrival times of the P and S waves and the greatest recorded amplitude (the peak height of the Swave). Millions of minor earthquakes occur every year worldwide, equating to hundreds every hour every day. On the other hand, earthquakes of magnitude ≥8.0 occur about once a year, on average. The largest recorded earthquake was the Great Chilean earthquake of May 22, 1960, which had a magnitude … See more The Richter scale , also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his … See more Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective … See more These formulae for Richter magnitude ML are alternatives to using Richter correlation tables based on Richter standard seismic event ( • The … See more 1. ^ Kanamori 1978, p. 411.
