GEOLOGY

Detailed explanation-1: -Another scale measures the intensity, or the effects, of an earthquake on a particular place. The Modified Mercalli intensity scale is a subjective evaluation based on observations by people.

Detailed explanation-2: -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. The intensity differs from the magnitude which is related to the energy released by an earthquake.

Detailed explanation-3: -The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.

Detailed explanation-4: -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.

Detailed explanation-5: -The Mercalli Scale Another way to measure the strength of an earthquake is to use the observations of the people who experienced the earthquake, and the amount of damage that occurred, to estimate its intensity.
