Advanced National Seismic System (ANSS)

The Advanced National Seismic System (ANSS) is a nationwide network of seismic sensors that monitors and detects earthquakes across the United States. It collects real-time data on ground vibrations, helping scientists track earthquake activity, determine their locations and sizes, and improve understanding of earthquakes' behavior. This information supports public safety efforts, emergency response, and infrastructure resilience. By providing timely and accurate data, ANSS enhances our ability to respond effectively to seismic events and advance earthquake research and preparedness initiatives.
