Earthquake Bulletin



The Richter scale – also called the Richter magnitude scale or Richter's magnitude 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. Because of various shortcomings of the M L scale.
