GEOLOGY

Detailed explanation-1: -Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.

Detailed explanation-2: -The correct option is B. Richter Scale. The intensity of an earthquake is expressed in terms of a magnitude on a scale called Richter scale. Really destructive earthquakes have magnitudes higher than 7 on the Richter scale.

Detailed explanation-3: -The intensity is the measure of shaking at each location, and this varies from place to place, depending mostly on the distance from the fault rupture area.
