"Assess the state of affairs regarding damage as soon as possible.

Act in close coordination with local governments and, under the principle of prioritizing human life above all else, spare no effort in our emergency disaster responses, including saving lives and rescuing disaster victims, with the Government working as one," it added.

A tsunami warning has been issued for the eastern Pacific coast of Hokkaido and other widespread coastal areas. The Japan Meteorological Agency (JMA) advised residents to check the estimated arrival times and expected wave heights via their official website.

In the United States, the Hawaii Emergency Management Agency also posted an urgent update on X, stating:

Meanwhile, in the Philippines, the Presidential Broadcast Service ' Radyo Pilipinas, citing PHIVOLCS (Philippine Institute of Volcanology and Seismology), reported:

"PHIVOLCS issued a Tsunami Warning following an 8.7 magnitude earthquake that struck the east coast of Kamchatka, Russia.

According to PHIVOLCS, tsunami waves less than one (1) meter high are expected to affect the coastal areas of the Philippines facing the Pacific Ocean.
