FAQ
Reader questions
What should I do if I receive a tsunami alert on my phone while I am on a beach in Hawaii?
Move immediately to higher ground or inland following the nearest marked evacuation route; do not wait for sirens or further messages, and avoid reentering the coast until authorities issue an all clear.
How can I distinguish a tsunami Warning from an Advisory when sirens sound?
Steady, continuous sirens generally signal a Warning requiring evacuation, while short intermittent tones or no sirens often accompany an Advisory, which means stay away from the water and monitor official updates.
Are hotels in coastal areas required to have tsunami evacuation plans and designated vertical evacuation structures?
Yes, hotels in tsunami hazard zones must have approved evacuation plans, clearly posted routes, and designated high-rise vertical evacuation areas, and staff are trained to guide guests during an alert.
What if I am driving when a tsunami alert is issued and the roads are congested?
Turn on your radio for updated instructions, avoid stopping on bridges or low-lying roadways, and if safe, drive toward higher ground inland; if movement is impossible, leave the vehicle and move on foot to elevated terrain away from the coast.
