Detailed explanation-1: -The higher the magnitude of the earthquake on the Richter scale the greater the intensity of the earthquake and thus the greater the damage.
Detailed explanation-2: -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.
Detailed explanation-3: -In the United States, we use the Modified Mercalli (MMI) Scale. The Mercalli Scale is based on observable earthquake damage.
Detailed explanation-4: -Richter scale (ML), quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. The earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.
