Though expected wave heights are less than one meter, even low-level tsunamis can create dangerous coastal conditions—especially for shoreline communities and beachgoers.
Tsunamis form when sudden seismic activity causes abrupt movement of ocean water. The impact, while sometimes minor, can still pose serious threats, including strong currents, unexpected wave surges, and flooding of coastal properties. People in low-lying areas should treat any tsunami advisory seriously, as water can rise rapidly and unpredictably.
How to Prepare and Evacuate Safely
Phivolcs urges those living close to coastlines to:
-
Move farther inland, especially if your home is near the beach.
-
Avoid visiting beaches, river mouths, and seaports until the advisory is canceled.
-
Secure important documents and belongings in waterproof containers.
-
Keep a go-bag ready with food, water, flashlight, radio, medicines, and clothes.
-
Follow updates via official channels and cooperate with local authorities.

Final Reminder for Public Safety
Though the waves expected are modest, Phivolcs emphasizes: “People whose houses are located very near the shoreline of these provinces are advised to move farther inland.” Coastal residents should monitor for any updates and wait for the official cancellation of the advisory before returning to affected areas.
Your best defense is preparation and vigilance. Stay safe, keep calm, and follow trusted sources for continued information.
