What measure of an earthquake depends on how close you are to the force?

The measure of an earthquake that depends on proximity to the seismic force is called the "intensity" of the earthquake, often assessed using the Modified Mercalli Intensity (MMI) scale. Intensity reflects the effects of the earthquake on people, buildings, and the Earth's surface, varying with distance from the epicenter. In contrast, the magnitude of the earthquake, measured on scales like the Richter or moment magnitude scale, is a measure of the energy released at the source and remains constant regardless of location.
