A small country with the large population usually suffers from natural calamities such as earthquakes or volcanoes .: And on March 11, 2011, an earthquake struck off the coast of Japan , churning up a devastating tsunami that swept over cities and farmland in the northern part of the country and set off warnings as far away the west coast of the United States and South America. Recorded as 9.0 on the Richter scale, it was the most powerful quake ever to hit the country. As the nation struggled with a rescue effort, it also faced the worst nuclear emergency since Chernobyl; explosions and leaks of radioactive gas took place in three reactors at the Fukushima Daiichi Nuclear Power Station that suffered partial meltdowns, while spent fuel rods at another reactor overheated and caught fire, releasing radioactive material directly into the atmosphere. Japanese officials turned to increasingly desperate measures, as traces of radiation were found in Tokyo's water and in water pouring from the reactors into the ocean.Slide 8: The Fukushima I , Fukushima II , Onagawa Nuclear Power Plant and Tōkai nuclear power stations , consisting of a total eleven reactors, were automatically shut down following the earthquake. [146] Higashidōri , also on the northeast coast, was already shut down for a periodic inspection. Cooling is needed to remove decay heat after a reactor has been shut down, and to maintain spent fuel pools. The cooling process is powered by emergency diesel generators, as well as in the case of Rokkasho nuclear reprocessing plant . [147] At Fukushima I and II tsunami waves overtopped seawalls and destroyed diesel backup power systems, leading to severe problems at Fukushima I, including two large explosions and radioactive leakage. Over 200,000 people were evacuated. [148] Sea water was pumped onto the plant to attempt to cool it. Europe's energy commissioner Guenther Oettinger , in remarks to the European Parliament on 15 March, ignored the damage wrought by the tsunami along the coast and called the nuclear disaster an "apocalypse", saying that the word was particularly well chosen, and that Tokyo had almost lost control of events at the Fukushima power plant. [149]Slide 9: Fukushima I and II Nuclear Power Plants Main articles: Fukushima I nuclear accidents , Timeline of the Fukushima I nuclear accidents , and Timeline of the Fukushima II nuclear accidents Japan declared a state of emergency following the failure of the cooling system at the Fukushima I Nuclear Power Plant , resulting in the evacuation of nearby residents. [150][151] Officials from the Japanese Nuclear and Industrial Safety Agency reported that radiation levels inside the plant were up to 1,000 times normal levels, [152] and that radiation levels outside the plant were up to 8 times normal levels. [153] Later, a state of emergency was also declared at the Fukushima II nuclear power plant about 11 km (7 mi) south. [154] This brought the total number of problematic reactors to six. [155]Slide 10: Onagawa Nuclear Power Plant A fire occurred in the turbine section of the Onagawa Nuclear Power Plant following the earthquake. [147][194] The blaze was in a building housing the turbine, which is sited separately from the plant's reactor, [150] and was soon extinguished. [195] The plant was shut down as a precaution. [196] On 13 March the lowest-level state of emergency was declared regarding the Onagawa plant as radioactivity readings temporarily [197] exceeded allowed levels in the area of the plant. [198][199] Tohoku Electric Power Co. stated this may have been due to radiation from the Fukushima I nuclear accidents but was not from the Onagawa plant itself. [200]Slide 11: Tōkai Nuclear Power Plant The number 2 reactor at Tōkai Nuclear Power Plant was shut down automatically. [146] On 14 March it was reported that a cooling system pump for this reactor had stopped working; [201] however, the Japan Atomic Power Company stated that there was a second operational pump sustaining the cooling system, but that two of three diesel generators used to power the cooling system were out of order.

Japanese officials turned to increasingly desperate measures, as traces of radiation were found in Tokyo's water and in water pouring from the reactors into the ocean. As of April 7, the official death toll had been raised to 12,600, and more than 14,700 people were listed as missing, although there may be some overlap between the two groups. The final toll is expected to reach nearly 20,000. More than 160,000 people remained housed in temporary shelters; tens of thousands of others evacuated their homes due to the nuclear crisis.
