Earthquake sensor networks are systems of connected instruments designed to detect ground motion, monitor seismic activity, and provide data for earthquake analysis. These networks consist of multiple sensors placed across geographic regions where earthquakes are likely to occur. The sensors collect data about vibrations in the Earth’s crust and transmit the information to monitoring centers.
Earthquakes occur due to sudden movement along geological faults, releasing energy as seismic waves. Sensor networks are designed to detect these waves quickly and analyze them in real time.
Modern earthquake monitoring relies on multiple technologies working together. Each component plays a role in capturing, transmitting, and analyzing seismic data.
