WebApr 11, 2005 · The Richter scale was developed in 1935 by American seismologist Charles Richter (1891-1989) as a way of quantifying the magnitude, or strength, of earthquakes. WebMar 15, 2011 · The old Richter magnitudes, which aren't used anymore, were calculated from ground movements (the amplitudes of seismic waves). So-called moment magnitudes, used since the 1970s, are based on a more complicated formula but were designed to be comparable for most earthquakes. The magnitude scale is logarithmic.
