Updates on the Tsunami warnings

The Tsunami warnings are still in place as of 1.25 am on December 9th 2025, for the east coast of Hokkaido, Aomori and Iwate prefectures. There is also a Tsunami advisory for Miyagi prefecture. Please remember, that even if the initial Tsunami were low, they can gain strength over time. Moreover, further after-quakes may cause further tsunami. Please don't let your guard down. If you have not yet already, please evacuate immediately if you are in the effected regions.

Also, it is very important that you don't return to your home until the warnings and advisories are lifted. What has happened in the past is that people have lost their lives after returning to their home too early. Because the initial Tsunami can be low, people think it is safe to go back home. But often the stronger Tsunami come later. Tsunami can occur for days after the initial earthquake, especially when there are several more tremors observed in the region.

So far the highest tsunami observed was at 1:09 am at Kuji Port at the northeastern coast of Iwate Prefecture, Japan, along the Pacific Ocean. The waves were 70 centimeter high. Several Tsunami between 30 and 50 centimeters high have been observed in various parts of the effected region between 11.15 pm and the time of writing this report at 1.22 am December 9th 2025.
