These images supplied by DigitalGlobe show reactors No. 1 and 3 at the Fukushima Daiichi nuclear power plant before and after the explosions on March 12 and March 14, respectively. DigitalGlobe's images show the extent of the damage sustained by the buildings that house Fukushima Daiichi's core reactor vessels. The 9.0 magnitude earthquake in Japan damaged the coolant systems at the reactors, and the resulting buildup of hydrogen and pressure in the reactors' outer buildings resulted in explosions. The nearby Fukushima Daini nuclear power plant has also experienced cooling problems at the Nos. 1, 2 and 4 reactors. The situation has continued to deteriorate, with an explosion occurring at Fukushima Daiichi reactor No. 2 at 6:10 a.m. local time, and a fire erupted and was subsequently extinguished at reactor No. 4 on March 15. In addition, radiation levels near the plant have risen to potentially hazardous levels and the Japanese government has announced a 30-kilometer no-fly zone and is expanding evacuation zones.
