Magnitude of earthquake is measured by.
The Richter scale (/ ˈ r ɪ k t ər /), 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 landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or M L .
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.
