    DigitalGlobe’s Continuing Coverage of Fukushima Daiichi NPP

    Subscribers to DigitalGlobe’s FirstLook service have unprecedented access to pre-and-post event crisis satellite imagery, like that which was used in the creation of this report. Please see DigitalGlobe.com/FirstLook or contact DigitalGlobe Customer Service at +1 303.684.4561 for additional details and ordering information. Coming soon, subscribers to DigitalGlobe’s new FirstWatch service will also be able to receive detailed imagery analytic reports that spotlight significant activity seen in the crisis-associated imagery.

    DigitalGlobe continues to monitor developments closely in and around the heavily damaged Fukushima Daiichi nuclear power complex in northeastern Japan. New satellite imagery collected at 10:55 AM local time (01:55 GMT) on March 17th, 2011 confirms significant damage to at least three of the six unit reactor buildings in the complex, one probable transformer building and other nearby support building and infrustructure.

    According to a report released by Stratfor, a leading global intelligence firm, on March 15, 2011, an "explosion and a fire occurred in two reactors at the Fukushima Daiichi nuclear power plant on March 15. The explosion took place at 6:10 a.m. local time at reactor No. 2, which had seen nuclear fuel rods exposed for several hours after dropping water levels due to mishaps in the emergency cooling efforts." Stratfor also reported that a fire later erupted in reactor No. 4 and was subsequently extinguished. Read more: Red Alert: Radiation Rising and Heading South in Japan | STRATFOR

    Notable activity includes: • Evidence of a recent explosion can be seen at the Unit 4 reactor building where the side and portions of the roof have been damaged or destroyed. • Steam is still venting from the Unit 3 reactor building, which was heavily damaged in a previous explosion. • Unit 2 reactor building is also emitting steam from the eastern wall, probably enabled by workers removing a panel or cutting a vent to let the steam escape from the structure. • Unit 1 reactor building remains damaged from a previous explosion. • At least two additional support buildings including one probable transformer building, located immediately to the west of Units 1 and 2, are also damaged on the eastern sides of both structures. Additionally, piles of debris can be seen in and around the sides of the buildings.

    Finally, the sides and roof of the Unit 5 and Unit 6 reactor buildings appear to be intact. No significant activity is seen at either of the reactor buildings.
