The Modified Mercalli Intensity Scale is a system used to measure the intensity of an earthquake based on its observed effects on people, buildings, and the Earth's surface. Unlike the Richter scale, which measures the energy released, the Modified Mercalli scale focuses on the impact and damage caused by the quake, using a scale from I (not felt) to XII (total destruction). This scale helps scientists and emergency responders understand the severity of an earthquake in specific areas. It considers factors such as structural damage, human reactions, and changes in the landscape, providing valuable information for disaster response and recovery efforts.
