Immediate Response and Evacuations
What Happened?
On July 29, 2025, Hawaii was placed under a tsunami warning following a massive 8.8 magnitude earthquake off the east coast of Kamchatka, Russia. This event triggered urgent evacuations and widespread alertness across the Hawaiian Islands as residents brace for the tsunami’s impact[1][2][3].
Immediate Response and Evacuations
As a precaution, Hawai’i County officials ordered the evacuation of all coastal inundation zones to protect residents living near the shore. The first tsunami wave was expected to arrive around 7:17 p.m. on the Big Island, with mandatory evacuation deadlines set for 6:15 p.m[1].
Emergency shelters have been opened, and officials strongly urged everyone in evacuation zones to relocate inland or to higher ground immediately. Those outside these zones were advised to stay off roads to reduce congestion and keep emergency routes clear[1].
What to Expect?
According to the Pacific Tsunami Warning Center and Hawaii Emergency Management Agency, multiple waves can follow the initial impact, sometimes with varying strength. The warning remained in effect until the threat was fully assessed and cleared.
Residents were advised to avoid beaches, harbors, rivers, and low-lying coastal areas. Importantly, even after the first waves subside, areas can remain dangerous due to strong currents and flooding[2][5].
How to Stay Safe
- Follow official orders about evacuations without delay.
- Stay informed through local news, official alerts, and live updates from emergency management agencies.
- Prepare an emergency kit with essentials like water, food, medications, and important documents.
- Do not return to evacuated areas until authorities confirm it is safe.
