tsunami warning
Coastal danger signal
A tsunami warning is an official alert that a tsunami is imminent or already occurring, urging coastal residents to evacuate to higher ground immediately.
Unlike a tsunami watch, which indicates a potential threat, a warning means the danger is confirmed and action must be taken: A tsunami warning was issued minutes after the earthquake struck.
