Expected Timeline for Tsunami Waves
The initial tsunami waves are anticipated to reach Hawaii around 7 PM local time, approximately two and a half hours from now. The National Weather Service has cautioned residents to prepare for potential impacts.
Evacuations in Japan
Workers at Japan’s damaged Fukushima nuclear plant were evacuated following the earthquake. “We have evacuated all workers and employees,” confirmed a spokeswoman for plant operator TEPCO, adding that “no abnormality” has been observed at the site.
Reports of Tsunami in Kamchatka
In Russia, the earthquake triggered tsunami waves measuring between 3 to 4 meters (10 to 13 feet). Sergei Lebedev, the regional minister for emergency situations, urged residents to “move away from the shoreline of the peninsula.”
Warnings for New Zealand and Other Regions
New Zealand’s National Emergency Management Agency has warned of powerful and erratic sea currents and shoreline surges in the aftermath of the earthquake. “Those in or around the sea—including beaches, shorelines, harbors, marinas, rivers, and estuaries—should leave the water and stay clear of the area,” they advised.
International Coordination and Preparedness
The Japanese government has established a task force to collect information and coordinate a response in the event of a crisis. Tsunami effects are expected to reach New Zealand around midnight local time.
As the situation develops, authorities across the Pacific are urging residents to remain vigilant and to stay informed. For the latest updates, visit tsunami.gov.
