Earthquake measurement
A measure of earthquake magnitude based on the area of fault that moved, the amount that it moved, and the friction between the rocks. Developed by Caltech's Hiroo Kanamori and seismologist Thomas C.

Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. Geologists locate the epicenter of an earthquake by taking measurements from three seismograms. These are measured at seismic stations and give the distance that the earthquake’s waves traveled in order to reach the station. These three dis...…
