Earthquake monitoring is the process of tracking and detecting seismic activity to understand and predict earthquakes. This involves the use of seismometers and other sensors to measure ground motion, as well as data analysis techniques to interpret the information collected. Earthquake monitoring is crucial for early warning systems, hazard assessment, and research into the causes and effects of earthquakes. Major organizations such as the United States Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC) are responsible for monitoring earthquakes worldwide to help protect communities and infrastructure from seismic events.
