What instruments to predict tsuamis?

Instruments used to predict tsunamis include tide gauges, which measure sea level changes, and buoys equipped with wave sensors that detect variations in ocean surface height. Tsunami warning centers also utilize deep-ocean tsunami detection systems, such as the DART (Deep-ocean Assessment and Reporting of Tsunamis) buoys, which monitor pressure changes on the ocean floor. Additionally, seismic monitoring networks help identify earthquakes that could generate tsunamis. Together, these tools enable timely warnings to mitigate the impact of tsunamis on coastal communities.
