Jun 11, 2023 · The Richter scale measures the energy produced during an earthquake, while the Mercalli scale assesses the amount of damage that an earthquake can cause. On a scale from I (not felt) to XII (complete devastation), the Mercalli scale measures the impacts of an earthquake on the Earth’s surface, humans, natural items, and man-made buildings.”. Updated on November 04, 2019 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.*Abbreviated descriptions from The Modified Mercalli Intensity (MMI) Scale.

Intensity scales assign whole numbers usually from I to XII (always written in roman numerals) to describe these observed levels of shaking. An intensity of 1 means the earthquake was not felt, while 12 means absolute and total destruction. In Jamaica we formerly used the Modified Mercalli Scale (MMS - 1956 version).Although numerousintensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes, the one currently used in the United States is the Modified Mercalli (MM) Intensity Scale.
