The Richter scale (M L), the first and most well-known magnitude scale, was developed by Charles F. Richter (1900-1985) at the California Institute of Technology. This was the magnitude scale used historically by early seismologists.Magnitude is the most commonly used measure to describe the overall strength or size of an earthquake. The magnitude of an earthquake is expressed in decimal fractions and whole numbers. For example, a magnitude of 5.3 is considered a moderate earthquake whereas a magnitude of 6.3 is a strong earthquake. How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth.

The magnitude of earthquake is determined from measurements on seismographs, whereas the intensity is determined […]Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. Remember that for each unit increase in magnitude:

Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.
