In these combo images made from Japan's NHK television, the Fukushima Daiichi power plant's Unit 1 is seen before (top) and after (bottom) an explosion in Okumamachi, Fukushima prefecture, Japan, Saturday, March 12, 2011. The walls of the building at the nuclear power station crumbled Saturday as smoke poured out and Japanese officials said they feared the reactor could melt down following the failure of its cooling system in a powerful earthquake and tsunami. The damaged steel structure of Unit 1 can be seen at left after the walls crumbled. Japanese characters read: "before 9 a.m., top," and "at around 4:30 p.m."
