Mercalli scale intensity

The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It quantifies the effects of an earthquake on the Earth's surface, humans, objects, and man-made structures on a scale from I (not felt) to XII (total destruction).

The Modified Mercalli (MM) Intensity Scale is used in the United States. Based on Giuseppe Mercalli's Mercalli intensity scale of 1902, the modified 1931 scale is composed of increasing levels of intensity that range from observable quake impacts from light shaking to catastrophic destruction. Intensity is reported by Roman numerals.Jul 1, 2021 · Earthquake Intensity - Modified Mercalli Intensity (MMI) Scale.

The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. Rather, they classify earthquakes by the effects they have (and the destruction they cause). 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. It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann.The Mercalli Scale: A Measure of Intensity Earthquake intensity is a measure of the effects of an earthquake at a particular place.
