2011 Sendai Earthquake And Tsunami, Tōhoku Region, Pacific Ocean

A fire from the turbine section of the Onagawa Nuclear Power Plant following the earthquake was reported by Kyodo News. The blaze was in a building housing the turbine, which is sited separately from the plant's reactor, and was soon extinguished.
On 13 March the lowest-level state of emergency was declared regarding the Onagawa plant by TEPCO, as radioactivity readings temporarily exceeded allowed levels in the area of the plant. TEPCO stated this was due to radiation from the Fukushima I nuclear accidents and not from the Onagawa plant itself.
