– The common earthquake Richter Scale is a measure of how much ground movement a local earthquake produces. For example, an R=5.0 earthquake produces 10 times more ground movement than an R=4.0 earthquake. This scale is calibrated so that an R=0 earthquake at a distance of 100 km produces a ground change of 1 micron (10

Magnitude is the size of the earthquake. An earthquake has a single magnitude. The shaking that it causes has many values that vary from place to place based on distance, type of surface material, and other factors. See the Intensity section below for more details on shaking intensity measurements. Types of Magnitudes

Calculator for the comparison of two Earthquake magnitudes given in the Richter scale. The Richter scale is the most frequently used to measure earthquake magnitudes.
