Honolulu, HI – A tsunami alert in Hawaii can impact every island within hours or less, making it critical to act immediately when warnings are issued.
According to the National Weather Service Pacific Tsunami Warning Center, a Tsunami Warning means widespread coastal flooding and destructive waves are expected or already occurring. Residents in evacuation zones across Oahu, Maui, Kauai, and the Big Island must move to higher ground without delay. In Honolulu, that means leaving areas near Waikiki, Ala Moana, and Honolulu Harbor and heading inland or above designated elevation zones. Do not wait for sirens to stop—multiple waves can arrive minutes apart.
A Tsunami Advisory signals strong currents and dangerous surges. This is not a full evacuation, but all beaches, harbors, and nearshore waters become unsafe. Boaters should remain in port, and residents should stay well away from shorelines.
A Tsunami Watch means a tsunami is possible after a distant earthquake. Use this time to prepare, fuel vehicles, and review evacuation routes, especially in low-lying coastal communities like Hilo and Kahului.
An Information Statement indicates no immediate threat.
Hawaii uses a statewide outdoor siren system, often sounding within minutes. Residents should act immediately, monitor official alerts, and expect updates as conditions evolve.
