Modified Mercalli intensity scale - Wikipedia
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.
Échelle de Mercalli — Wikipédia
L'échelle de Mercalli est une échelle de mesure de l'intensité d'un séisme, qui se fonde sur l'observation des effets et des conséquences du séisme en un lieu donné. Il est important de distinguer l'intensité d'un séisme de sa magnitude, laquelle mesure l'énergie libérée …

Mercalli intensity scale - Simple English Wikipedia, the free …
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 energy of an earthquake directly.
Échelle de Richter vs échelle de Mercalli : différence et comparaison
L'échelle de Richter évalue la magnitude de l'événement sismique d'un tremblement de terre et d'autres régions quantifiables numériquement, tandis que l'échelle de Mercalli est utilisée pour évaluer la magnitude d'un tremblement de terre.
Échelle de Mercalli : définition, degrés et différence avec l'échelle ...
Nov 29, 2024 · Créée en 1902 par le géologue italien Giussepe Mercalli, l'échelle de Mercalli mesure qualitativement l'intensité ou la violence d'un tremblement de terre. En 1931, elle a été modifiée par Wood et Neumann, d'où son appellation actuelle d'échelle de Mercalli modifiée.
The Modified Mercalli (MM) Intensity Scale
Adapted from Sieberg's Mercalli-Cancani scale, modified and condensed. Note: The Modified Mercalli scale is designed to describe the effects of an earthquake, at a given place, on natural features, on industrial installations and on human beings.
Mercalli Earthquake Intensity Scale - ThoughtCo
Nov 4, 2019 · The modified Mercalli intensity scale rates the observed impact of earthquakes from I to XII. Find out more here.
The Modified Mercalli Intensity (MMI) Scale assigns intensities …
The Modified Mercalli Intensity value assigned to a specific site after an earthquake is a more meaningful measure of severity to many people than is magnitude, because intensity refers to the effects actually experienced at that place.
Mercalli Scale Explained - Degrees, Uses, and How It Differs from …
Nov 28, 2024 · The Mercalli Intensity Scale measures earthquake effects through observable damage and human experience, using 12 levels from barely noticeable tremors to total destruction. Created in 1902 and modified in 1931, this scale helps emergency responders assess damage patterns and engineers design seismic-resistant structures.
