What is the primary function of tsunami sirens installed in vulnerable coastal zones?
Answer
To provide an unmistakable auditory cue for immediate evacuation
Tsunami sirens are powerful, high-decibel acoustic devices meant to be heard clearly even over the ambient noise of a coastal environment. Their primary purpose is to function as a universal, non-verbal alarm that triggers an immediate response from the public, specifically the action of evacuating. Unlike digital notifications that may require context or explanation, the siren is designed to be recognized instantly as a sign of immediate danger that necessitates rapid movement to higher ground.
