Seismic networks

Definition

Seismic networks are systems of interconnected instruments and sensors that monitor seismic activity, such as earthquakes and volcanic eruptions, by measuring ground motion. These networks provide crucial data that helps scientists assess natural hazards and conduct risk assessments for affected areas, leading to better preparedness and response strategies.
