What is Intensity and the Mercalli Intensity Scale?
The amount of shaking that occurs on the surface due to an earthquake is called the intensity. It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,…IX, X, and often displayed with color codes ranging from light blue to dark red.
Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.
