The Japan Meteorological Agency has issued a tsunami warning and advisory on July 30 due to a large earthquake with a magnitude of 8.8 near the Kamchatka Peninsula in Russia.

People near the coast or rivers should evacuate to a safe place immediately.

Tsunami warnings have been issued for a wide area from Hokkaido to Kyushu.

Warnings for areas include the eastern Pacific coast of Hokkaido, the central Pacific coast of Hokkaido, the western Pacific coast of Hokkaido, the Pacific coast of Aomori Prefecture, Iwate Prefecture, Miyagi Prefecture, Fukushima Prefecture, Ibaraki Prefecture, the town of Kujukuri and the Sotobo and Uchibo regions of Chiba Prefecture, the Izu Islands, the Ogasawara Islands, Sagami Bay and the Miura Peninsula, Shizuoka Prefecture, the outer coast of Aichi Prefecture, southern Mie Prefecture, and Wakayama Prefecture.

People living in coastal areas or along rivers where warnings have been issued, or those in the sea should immediately evacuate to high ground, evacuation buildings, or other safe locations.

The Japan Meteorological Agency held a press conference at 10:10AM on July 30 and warned that the tsunami would strike repeatedly over a long period of time, urging people to remain in safe locations regardless of the height of the observed tsunami until the warnings have been lifted.

Additionally, they are calling for caution regarding earthquakes occurring in distant locations, as it may take time for the warnings to be lifted. 

It is necessary to remain vigilant for another day, as the second wave is expected to be more severe than the first, across a wide area from Hokkaido to Kagoshima.
