Pacific nations from Japan to the western United States are issuing warnings and ordering evacuations bracing for a tsunami after a powerful earthquake struck off Russia's Far Eastern Kamchatka Peninsula.

The Fukushima Daiichi plant was the site of a major nuclear disaster following the devastating 9.0 magnitude Japan earthquake and tsunami in 2011. TEPCO added that there have been no injuries or abnormalities recorded at the plants, but that they will continue to monitor tsunami warnings.

A tsunami advisory was also issued for the Aleutian Islands in Alaska​, and a tsunami watch was issued for Hawaii, the U.S. National Weather Service said.
