The Richter scale , 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 ML . Because of various shortcomings of the original ML scale, most seismological authorities now u… WebNov 11, 2024 · Consequently, they have made adjustments to the scale of sizes.
