Answer» A tsunami warning system (TWS) is used to detect tsunamis in ADVANCE and issue warnings to prevent loss of life and damage. It is made up of two equally important components: a network of SENSORS to detect tsunamis and a communications infrastructure to issue timely alarms to permit EVACUATION of the coastal areas. There are two distinct TYPES of tsunami warning systems: INTERNATIONAL and regional. |
