GEOLOGY

Detailed explanation-1: -The intensity of an earthquake is measured by the Modified Mercalli Scale. It is named after Mercalli, an Italian seismologist. It measures the energy released during the earthquake. The intensity scale takes into account the visible damage caused by the event.

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 Modified Mercalli scale measures the earthquake’s effect on people, property and ground damage. Roman numerals are used to rate the intensity and damage. An earthquake may have a different intensity rating at different locations. Damage is usually lessened with distance from the earthquake’s epicenter.

Detailed explanation-4: -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).

Detailed explanation-5: -The Mercalli Intensity Scale measures the intensity of an earthquake by observing its effect on people, the environment and the earth’s surface. The Richter Scale measures the energy released by an earthquake using a seismograph.
