What are the instrument used to detect tsunami ? – ScienceReport
How the detection process worksAn undersea earthquake causes disturbance to both the sea floor and body of ocean above it. Seismic waves travel much faster than tsunami waves away from the earthquake source. Earthquakes are detected through a network of seismic monitoring stations. Any resulting tsunami are then verified by sea-level monitoring stations and deep-ocean tsunami detection buoys. The seismic monitoring stations can determine the location and depth of earthquakes that have the potential to cause tsunami. The sea-level gauges and deep-ocean detection buoys measure any abnormal changes in sea level to verify if a tsunami has been generated.
