How does the mercalli scale rate earthquakes

WebJul 5, 2024 · There are two commonly-used scales to rate earthquakes 1) the Richter Scale and 2) the Mercalli Scale. The force at which an earthquake shakes the ground is measured with the Richter Scale, which rates the earthquake's actual force on a scale from 0 to 9. A 0 level Richter rating cannot even be felt by a person, while a rating of 8 shakes hard ... WebJul 1, 2024 · Earthquake Intensity - Modified Mercalli Intensity (MMI) Scale. The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place.
