5 Facts About Tsunami Warning System


A tsunami warning system is used to detect tsunamis in advance and issue warnings to prevent loss of life and damage.

A tsunami, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.

There are two distinct types of tsunami warning systems: international and regional.


When operating, seismic alerts are used to instigate the watches and warnings; then, data from observed sea level height are used to verify the existence of a tsunami.

Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.


Other systems have been proposed to augment the warning procedures; for example, it has been suggested that the duration and frequency content of t-wave energy is indicative of an earthquake's tsunami potential.

An earthquake is the perceptible shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's crust that creates seismic waves.
