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 the energy of an earthquake directly. Rather, they classify earthquakes by the effects they have (and the destruction they cause).develop Mercalli-Cancani-Sieberg (MCS) scale in 1923, and the scale was expanded to 12 degrees i.e. I to XII. Wood and Neumann gave a new version of the MCS scale, which came in use in USA as Modified Mercalli (MM) Scale.

[15] At Intensity 7, it becomes impossible to move at will. [13] The intensity was made in the wake of the 1948 Fukui earthquake. The Richter Scale (called Local Magnitude scale) is used to measure the magnitude. There are other magnitude scales, like the moment magnitude, Body Wave Magnitude, Surface Wave Magnitude, and Wave Energy Magnitude. These numerical magnitude scales have no upper and lower limits; the magnitude of a very small earthquake can be zero or even …The Richter scale is a scale of numbers used to tell the power (or magnitude) of earthquakes.

Advertisement This often comes up when when people talk about earthquake activity along the Pacific coast of the United States. Seismologists have predicted that...While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake's magnitude by measuring the seismic waves that cause the earthquake. The two scales have different applications and measurement techniques.Magnitude scales do not used express damage and nor do they provide a direct indication of the shaking level on the ground surface. However, Intensity scales, like the Modified Mercalli Intensity Scale or the Japan Meteorological Agency’s Seismic Intensity Scale, do provide an indication of the extent and distribution of the damage caused from ground surface shaking caused by an earthquake. The proposed intensity scale is called the modified Mercalli (MM), scale (Wood and Neumann, 1931). It has been repeatedly revised: e.g., variants of this scale proposed by C. Richter (1958), R. Brazee (1978), and K. Stover and J. Coffman (1993). This scale is still widely used in many countries to determine earthquake strength.So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts. The Mercalli scale in its original form predates Richter and has its origins in the Rossi-Forel scale used in the 19 th century. It was modified by Giuseppe Mercalli, an Italian volcanologist, between 1884 and 1906.From Richter's (1958) book, Elementary Seismology.(Public domain.) The Richter Scale (M L) is what most people have heard about, but in practice it is not commonly used anymore, except for small earthquakes recorded locally, for which ML and short-period surface wave magnitude (Mblg) are the only magnitudes that can be measured.
