Deep-ocean Assessment and Reporting of Tsunamis (DART)

The Deep-ocean Assessment and Reporting of Tsunamis (DART) program is a system that detects tsunamis in the open ocean before they reach land. It uses specialized buoys equipped with sensors that monitor sea level and pressure changes caused by seismic activity. When a potential tsunami is detected, data is transmitted in real-time to warning centers, allowing authorities to issue alerts quickly. This early detection helps save lives and reduce property damage by providing critical time for evacuation and preparation. DART is a key component of global efforts to monitor and respond to underwater earthquakes that may generate tsunamis.
