The most common standard of measurement for an earthquake is the Richter scale, developed in 1935 by Charles F. Richter of the California Institute of Technology. The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it ... Caltech's Charles Richter conceptualized magnitude. He developed a method to numerically report the relative sizes of earthquakes before earthquake magnitude could be measured directly. He described the first magnitude scale, which came to be known as the Richter scale, in a paper published in 1935.The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.

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. This magnitude scale was referred to as ML, with the L standing for local.Most of these scales saturate at some magnitude and do not properly represent earthquake size for larger events. For example, the ML scale saturates over ML 6.0, while the MS scale can be used to about MS 8.0. The most modern scale is the moment magnitude scale MW, which can be used for a wide range of magnitudes and distances.

How much bigger is a magnitude 8.7 earthquake than a magnitude 5.8 earthquake?
