The intensity differs from the magnitude which is related to the energy released by an earthquake. There are multiple versions of the MM scale, the one listed here being ... The Mercalli Scale uses human observation to assess damage from an earthquake, while a Richter Scale uses instruments to measure how much force an earthquake produces, or the size of its waves. Today, we are going to look at the Mercalli Scale's damage rating and create a booklet to help inform citizens of potential danger.Both the Richter Scale and the Moment Magnitude Scale measure the amount of energy released by an earthquake.

It is sufficient to distinguish between small, moderate, or large earthquakes. This ...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.In 1858, John Mallet formally proposed the first edition of the macroseismic-intensity scale, which divided earthquakes into three categories according to their intensity: great, mean, and minor. These categories were labeled and coded on maps with different colors covering their respective ranges (Davison, 1921). Based on the above theory ...A modified Mercalli intensity scale is used to quantify the earthquake's effects.
