Tsunami warning system

system used to detect tsunamis and issue warnings, which typically is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely evacuation alarms

Tsunami warning system or TWS detects tsunamis and issues warnings to prevent loss of life and property. It consists of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to start evacuation before the big waves reach the land to let the people to rush to safety.[1]

There are two distinct types of tsunami warning systems: international and regional.[2] Both of those systems depend on the fact that tsunami waves travel, approximately, 15-30 times slower than seismic waves.[3]
