Seismic Monitoring

Definition

Seismic monitoring refers to the systematic observation and recording of seismic activity, particularly earthquakes, through a network of seismometers. This process is crucial for understanding the occurrence, magnitude, and impact of earthquakes, allowing researchers and engineers to analyze seismic data, improve safety measures, and enhance the prediction of future seismic events. By collecting real-time data from various locations, seismic monitoring supports risk assessment and informs emergency response strategies.
