What is Understanding Earthquake Magnitude Scales about?
The Richter scale is a quantitative measure of earthquake magnitude devised in 1935 by Charles Richter and Beno Gutenberg. It calculates magnitude from the amplitude of the largest seismic wave recorded on a seismograph. Each increase of one unit represents a tenfold increase in wave amplitude and 31 times more energy released. Later modified scales like the body-wave and surface-wave scales addressed limitations for large quakes but also saturated above magnitude 8. The current preferred scale is the momen
