Where is the intensity of an earthquake measured?

The intensity of an earthquake is measured using the Modified Mercalli Intensity (MMI) scale, which assesses the earthquake's effects on people, buildings, and the Earth's surface. This scale ranges from I (not felt) to XII (total destruction), based on observations and reports from individuals in different locations. In contrast, the magnitude of an earthquake, which quantifies its energy release, is typically measured using the Richter scale or the moment magnitude scale (Mw).
