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). When there is little damage, the scale describes how people felt the earthquake, or how many ...

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).
WebThe Mercalli intensity scale uses personal reports and observations to measure earthquake intensity but PGA is measured by instruments, such as accelerographs. It can be correlated to macroseismic intensities on the Mercalli scale [3] but these correlations are associated with large uncertainty. [4] ( See also: seismic scale ).
The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "Mw" magnitude usually reported for an earthquake). While shaking is cause… albernaz dallasWebBut only the moment magnitude scale is capable of measuring M8 (read "magnitude 8") Part three of our introduction to seismology series is an exercise about the Modified Mercalli Intensity scale which is used by seismologists to determine the magnitude and epicenter of earthquakes of the past.
