TSUNAMI WARNING SYSTEM

A Tsunami Warning System (TWS) is a system to detect tsunamis and issue warnings to prevent loss of life and property.

Detecting TsunamiSeismometers

Coastal tide gauges

Open-ocean tsunami buoys/DART Buoys

SEISMOMETERSWhen a tsunami event occurs, the first information available about the source of the tsunami is based only on the available seismic information.

Earthquakes are measured based on its magnitude recorded by a seismograph.
