Richter scale


Richter scale
The Richter scale, being of empirical numerical origin, does not directly reflect any subjective scale of earthquake intensities. In this table, an attempt is made to correlate a subjective scale with corresponding Richter magnitudes, imagining the observer to be near the epicenter of the earthquake.
A scale devised by Charles F. Richter (1900–1985) used to measure the magnitudes of earthquakes in terms of the amplitude and frequency of the surface waves. The scale runs from 0 to 10, about one quake a year registering over 8.
