Mercalli scale intensity.

The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.

Of existing intensity scales, the Sieberg scale, the "1956 version" of the MO'dified Mercalli scale, and Kawasumi's (1951) scale are the most satis-factory. None of them is suitable for use in all countries, and it may be considered a merit of Kawasumi's scale that it contains explicit referenceMoreover, Giuseppe Mercalli compiled a 6° intensity scale; to identify and categorize high-intensity seismic damage more accurately and meticulously, the seismic intensity was reclassified in reference to the R–F scale. This 6° standard was later extended to a 10° standard and translated in 1902.

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.Defining Earthquake Intensity – Modified Mercalli Intensity Scale Scientists calculate the magnitude of an earthquake based on geological events, i.e. measurable forces that occur within the earth.
