, measure of the magnitude of seismic waves from an earthquake. Devised in 1935 by the American seismologist Charles F. Richter (1900–1985) and technically known as the local magnitude scale, it has been superseded by the moment magnitude scale, which was

Unlike the more commonly known Richter scale, which measures the magnitude of an earthquake at its epicenter, the Mercalli scale measures the intensity of shaking in specific locations -- basically by measuring the destruction of buildings and natural structures.
