Tokyo Electric Power Co. said it evacuated all personnel from the crippled Fukushima Daiichi nuclear station early Wednesday after Japan issued a tsunami warning triggered by a magnitude-8.8 earthquake off Russia’s Kamchatka Peninsula. The Japan Meteorological Agency initially forecast waves of up to one metre but later raised its estimate to three metres, covering much of the country’s northern and eastern coastline. No abnormalities were detected at the dismantlement site, Tepco added. The Fukushima complex was devastated by a 9.0-magnitude quake and tsunami in March 2011, leading to the world’s worst nuclear accident since Chernobyl. Decommissioning work has been under way for more than a decade and is expected to stretch into the 2050s.
