Fukushima I and II Nuclear Accidents Overview Map showing evacuation and other zone progression and selected radiation levels. The Japanese reaction occurred after the Fukushima Daiichi nuclear disaster, following the 2011 Tōhoku earthquake and tsunami. A nuclear emergency was declared by the government of Japan on 11 March.
The Fukushima prefectural government reported radiation dose rates at the plant reaching 1.015 m Sv/h. [58] The IAEA stated on 13 March that four workers had been injured by the explosion at the Unit 1 reactor, and that three injuries were reported in other incidents at the site.
The Fukushima Hamadōri earthquake was succeeded by a number of smaller tremors; that same day, at least 11 earthquakes of magnitude 3.5 M j or higher were recorded near its epicentre. [16] Of the series, the strongest registered at a magnitude of 5.5 M j and occurred within 3.5 hours after the initial quake. [ 17 ]
[citation needed] At 11:15 JST on 14 March, the envisaged explosion of the building surrounding Reactor 3 of Fukushima 1 occurred, owing to the ignition of built-up hydrogen gas. [ 23 ] [ 24 ] The Nuclear and Industrial Safety Agency of Japan (NISA) reported, as with Unit 1, the top section of the reactor building was blown apart, but the inner ...
