GEOLOGY

Detailed explanation-1: -The Modified Mercalli scale rates the amount of damage from an earthquake. To locate the epicenter of an earthquake, geologists need data from two or more seismographs. In a seismograph, seismic waves cause the drum to vibrate. On a seismogram, higher lines drawn in the paper indicate weaker seismic waves.

Detailed explanation-2: -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-3: -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-4: -Which are true of the Modified Mercalli Intensity Scale? It describes the effect of shaking in everyday terms.

Detailed explanation-5: -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).
