Mercalli scale intensity
The Richter and MMS scales measure the energy released by an earthquake; another scale, the Mercalli intensity scale, classifies earthquakes by their effects, from detectable by instruments but not noticeable, to catastrophic. The energy and effects are not necessarily strongly correlated; a shallow earthquake in a populated area with soil of ... The Mercalli Intensity Scale was developed by the Italian volcanologist Giuseppe Mercalli in 1884 and expanded to include 12 degrees of intensity in 1902 by Adolfo Cancani. It was modified again by Harry O. Wood and Frank Neumann in 1931. It is known today as the Modified Mercalli Intensity Scale. Mercalli ratings, which are given as Roman ...

8.9: Magnitude vs. Intensity. Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.The most common intensity scale used in Australia is the 12-point Modified Mercalli scale. On this scale, intensities up to 5 are felt but cause no damage, while intensities from 6 to 12 cause increasing amounts of damage. A Modified Mercalli Intensity of six is abbreviated as MMI 6. Eventually, shaking intensity scales were developed to standardize the measurements and ease comparison of different earthquakes. Shaking intensity varied from barely perceptible to completely destructive. Since 1933, in the United States we have used what's called the Modified-Mercalli Intensity scale, a twelve-stage scale, numbered from I to XII.Each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value. Another important scale used by earthquake scientists is the Modified Mercalli Intensity (MMI) scale. The MMI scale estimates the intensity of shaking in the region around the ...it was the most common scale until the Mercalli Intensity scale (MI) was defined in 1902. This scale was modified in 1931 (intensities XI and XII were added to describe very damaging shaking and the definition of Modified Mercalli Intensity scale (MMI) is given in Table 8-1. Earthquakes are sometimes characterized by the maximum MMI reported.The effect of an earthquake on the Earth's surface is referred to as its intensity. Numerous intensity scales have been developed over the last several hundred years. The one currently used in the United States is the Modified Mercalli Intensity Scale developed in 1931.
