The magnitude is the most often cited measure of an earthquake's size, but it is not the only measure, and in fact, there are different types of earthquake magnitude. Early estimates of earthquake size were based on non-instrumental measures of the earthquakes effects.
Richter scale , Widely used measure of the magnitude of an earthquake, introduced in 1935 by U.S. seismologists Beno Gutenberg (1889–1960) and Charles F. Richter (1900–1985).The scale is logarithmic, so that each increase of one unit represents a 10-fold increase in magnitude (amplitude of seismic waves).
The magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of the area that slipped. The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale (ML).Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using …EARTHQUAKES The Richter Scale. On the Richter scale, the magnitude of an earthquake is related to the released energy E in joules (J) by the equation. log 10 E = 4.4 + 1.5M.
