Tsunami could be bad in Hanalei

Question

If you're in Hanalei I'd head up to Princeville just in case. Wave predicted to hit Hanalei at 7:10 HST. Hanalei Bay is a resonating bay that amplifies tsunami waves. Stay safe.

Answer

Thank you for sharing this important alert. Hanalei Bay, located on the north shore of Kauaʻi, is particularly vulnerable to tsunami waves due to its shape and orientation, which can amplify incoming swells. If a tsunami wave is predicted to hit Hanalei, immediate action is required to ensure safety.

Here are detailed steps and considerations for anyone in Hanalei or nearby areas:

Move to Higher Ground Immediately: Head inland or uphill — for example, Princeville or other elevated areas nearby. Even a small tsunami wave can be dangerous in Hanalei Bay due to the bay’s resonance effect.
Do Not Wait or Return to the Shore: Avoid beaches, river mouths, and harbors. Water levels can rise suddenly and currents will be strong.
Follow Official Instructions: Pay attention to warnings from local authorities, civil defense sirens, and emergency broadcasts. They will provide updated information about wave arrival times and evacuation orders.
Prepare an Emergency Kit: If possible, take essentials such as water, food, medications, important documents, flashlight, and a phone. Quick evacuation may be necessary.
Stay Informed: Keep a battery-powered radio or phone with alerts enabled to track the situation, as tsunami waves can come in multiple surges over hours.

Additional safety recommendations for Hanalei residents and visitors:

Ensure your family and travel companions know your meeting point on higher ground.
Secure or move vehicles and belongings away from low-lying coastal areas, if time allows.
After the first wave, remain in safe areas until authorities confirm the all-clear — tsunami waves often arrive in multiple waves over several hours.

In summary, the predicted tsunami for Hanalei Bay requires immediate evacuation to higher ground, such as Princeville, and adherence to official guidance. Safety should be the top priority, and staying informed and prepared is critical during this event.
