Understanding Intensity and the Mercalli Intensity Scale
The intensity of shaking on the surface following an earthquake is referred to as intensity. It is usually measured on the Modified Mercalli Intensity Scale (MMI), which spans from 1 (not felt) to 10 (extreme shaking), and is indicated in Roman numerals from I to X, often represented with color codes that transition from light blue to dark red.
Earthquake intensity predominantly relies on the magnitude and depth of the quake, as well as how far one is from the epicenter: greater distances generally result in lesser shaking intensity.
