WebMagnitude is the most common measure of an earthquake's size. It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like. The Richter scale is an outdated method for measuring magnitude that is no longer used by the USGS for large, teleseismic earthquakes. The Richter scale ... WebEarth radius (denoted as R 🜨 or ) is the distance from the center of Earth to a point on or near its surface.
