Global Seismographic Network

The Global Seismographic Network (GSN) is a worldwide system of highly sensitive seismic sensors that monitor Earth’s vibrations. It helps scientists detect and analyze earthquakes, volcanic activity, and other geological events in real-time. By providing precise data from around the globe, the GSN improves our understanding of Earth's interior and enhances early warning systems, reducing risks from natural disasters. Maintained by scientific agencies, it plays a vital role in advancing geophysical research and ensuring public safety through accurate seismic monitoring.
