Modified Mercalli Intensity (MMI) is a scale 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 quantifies the energy released, MMI focuses on the experience of the earthquake, ranging from I (not felt) to XII (total destruction). The MMI scale helps assess the impact of an earthquake in specific locations, providing valuable information for emergency response and recovery efforts. It considers factors such as structural damage, human reactions, and changes in the environment, making it a useful tool for understanding the effects of seismic events like those caused by tectonic plate movements.
