Jan 11, 2021 · The Richter scale measures the magnitude of an earthquake's largest jolt of energy. This is determined by using the height of the waves recorded on a seismograph. The Richter scale is logarithmic. The magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level. See below Earthquake magnitude. A number of different intensity scales have been set up during the past century and applied to both current and ancient destructive earthquakes. For many years the most widely used was a 10-point scale devised in 1878 by Michele Stefano de Rossi and Franƈois-Alphonse Forel. The Modified Mercalli Intensity Scale of 1931 is the basis for the U.S. evaluation of seismic intensity. Intensity is different than the magnitude in that it is based on observations of the effects and damage of an earthquake, not on scientific measurements. This means that an earthquake may have different intensities from place to place, but ...For many years, the Richter Scale was the most common and familiar earthquake magnitude scale, but as recording instruments have become increasingly ...
