A magnitude 8.8 earthquake struck the Kamchatka Peninsula in Russia, prompting Japan to issue a tsunami warning and evacuation order for its Pacific coastal areas, though no significant damage has been reported. However, the Japanese government advised that higher tsunamis could still occur, urging people to remain evacuated.

The Japan Meteorological Agency predicts that a tsunami will reach the Kamchatka Peninsula in Russia due to a strong earthquake that occurred on the 30th.

Around 9:40 a.m. on the 30th, the Japan Meteorological Agency issued a tsunami warning for the Pacific coastal areas of Hokkaido and Honshu, while a tsunami advisory was issued for Kyushu, Shikoku's Pacific coastal regions, and northern Hokkaido.

Earlier, a tsunami advisory had been issued for the Pacific coastal areas extending from Hokkaido to Kyushu, but as waves were predicted to rise higher, the warning was escalated to cover more than half of the targeted regions.

The areas under the warning included the eastern waters of Hokkaido, the northeastern Tohoku region of Honshu, the Greater Tokyo area in the Kanto region, and the Kansai region where Osaka is located.

In Japan, a tsunami advisory is issued when a tsunami of 1 meter or more is expected, while a tsunami warning is issued when a tsunami of 3 meters or more is predicted. If a tsunami warning is issued, residents must immediately evacuate to higher ground or safe buildings.

In response, the Japanese government set up an information contact office, and the public broadcaster NHK organized emergency disaster broadcasts. Coastal residents evacuated to building rooftops and high ground, but the tsunami height observed upon reaching the Japanese coastline was significantly lower than expected.

According to the Japan Meteorological Agency, a tsunami with a maximum height of 1 to 3 meters was forecast to hit the Pacific coastal area, but by noon, the observed tsunami height was only about 30 to 50 centimeters.

However, the Japanese government urged people to continue evacuating due to the possibility of higher tsunamis arriving. The Japan Meteorological Agency has also been reported to maintain tsunami advisories and warnings for specific regions.
