The most widely used scale is the Modified Mercalli Intensity Scale (MMI scale). It was originally introduced by the Italian seismologist Giuseppe Mercalli in 1902, and was modified and updated for "modern" building practices in 1931. It has twelve levels describing the strength of shaking. The Modified Mercalli Intensity Scale The effect of an earthquake on the Earth's surface is called the intensity.

The intensity of an earthquake varies by sites, and is not totally determined by its magnitude. The seismic scale most commonly used in the United States is the Mercalli Intensity scale (MMI). MMI quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and man-made structures.Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. 1. Using the Modified Mercalli (MM) scale included with this activity, determine a MM Intensity for each locality given in the exercise. When recording on your map, if there are several reports for the same town, use the largest indicated MM Intensity. Write the Roman numerals in the column for "Assigned MM Intensity" on your handout.Modified Mercalli Scale and PGA MMI MMI IV PGA (g) V 0.03 and below VI 0.03 – 0.08 VII 0.15 – 0.25 VIII 0.25 – 0.45 IX 0.45 – 0.60 X 0.60 – 0.80 XI 0.80 – 0.90 XII 0.90 and above The above table shows the approximate relationship between Modified Mercalli Intensity and …The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location.

Usually (but not always) the highest intensities are measured near the earthquake epicenter and lower intensities are measured ...Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. The intensity of the 1960 Chile Earthquake on the Mercalli Scale was XI. The mercalli scale of the Great Chilean earthquake was XI. The Chilean earthquake of February 27th, 2010 was magnitude 8.8 ...The intensity scale based on the Modified Mercalli Scale of 1931 (MM scale) measures the effects of seismic shaking.
