The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology. The mathematical device is used to compare the size earthquakes. On the Richter Scale, the magnitude of quake is expressed in whole numbers and decimal fractions.

How much does the ground shake during an earthquake? Scientists can tell using the Richter scale, which measures the shaking on a scale from 1.0 to 9.0. ... The recent Los Angeles quake measured 6.6 on the Richter Scale. The biggest quakes in history include a 1960 quake in Chile and the Indian Ocean quake in 2004 which caused...

On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions. ... The Richter Scale is not used to express damage. An earthquake in a densely populated area which results in many deaths and considerable damage may have the same magnitude as a shock in a remote area that does nothing more than...

The magnitude of most earthquakes is measured on the Richter scale, invented by Charles F. Richter in 1934. The Richter magnitude is calculated from the amplitude of the largest seismic wave recorded for the earthquake, no matter what type of wave was the strongest.
