A photo taken from Yomiuri Shimbun's jetliner shows a construction of frozen underground soil walls work starting at the reactor No. 1 (R) of the crippled Fukushima No. 1 nuclear power plant operated by Tokyo Electric Power Co.(TEPCO) in Okuma, Fukushima Prefecture on June 2, 2014. Japanese government and TEPCO created the walls to prevent a contaminated undergroundwater from entering the buildings and facilities at the plant.
In March 2011, an earthquake and tsunami devastated the eastern coast of Japan. Thousands of people were killed, and scores more were displaced as a result of the natural disaster. The earthquake and resulting tsunami caused the meltdown of a nuclear power station located in Fukushima Prefecture. Radioactive material leaked into the Pacific Ocean, and the area surrounding the plant became irradiated. This led to the development of an exclusion zone around the plant, and the evacuation of cities near the stricken nuclear site.
