DigitalGlobe acquired this satellite image of Japan's Fukushima nuclear complex on Feb. 2, 2012, almost a year after the tsunami. Click here for larger version.
Satellite images tracked the catastrophic impact of Japan's magnitude-9.0 earthquake and tsunami on the Fukushima nuclear complex and other key sites, and now they're tracking the reconstruction.
To mark Sunday's anniversary of the disaster, DigitalGlobe is releasing pictures showing "before, during and after" views of the devastation. You can see the three views of Fukushima here — but you really should check out our interactive slideshow to get a better sense of the changes that have taken place over the past year at Fukushima and at the Port of Sendai, which was destroyed in the tsunami.
"I'm struck by the progress, by how efficient the Japanese have been in reconstructing their infrastructure," Steve Wood, vice president of DigitalGlobe's analysis center, told me today. "In less than a year they've been able to turn this port into an active, functioning component. That's significant, considering that a year ago there were shipping containers, fires and mud covering that entire area. ... And there are literally hundreds of examples of that up and down the coast."
In the hours, days and weeks after the March 11 quake, satellite operators funneled fresh imagery to disaster workers, relief groups, government agencies and private companies coping with the aftermath. "We saw everything from big industrial partners who wanted to see the status of their factories, to government agencies involved in the actual reconstruction," Wood said.
Japanese officials and the U.S. military used the images to figure out which places were best for setting up aid operations, while relief organizations scanned wide-scale maps to see which areas were most in need of help. In places where planes weren't allowed to fly, "we were effectively the only game in town" for that initial post-quake aerial imagery.
Today, satellite images provide an effective way to gauge how much progress is being made, through comparisons of the before-during-and-after views. "To communicate and explain that to people is really an important and powerful tool that I've seen evolve over the years," Wood said. Pictures from space were important in the aftermath of the 2004 Indian Ocean quake and tsunami, they're important for Japan, and they'll be important for current and future hotspots such as Syria.
During Japan's crisis, Wood's team at DigitalGlobe was working 24/7, and the weeks and months have sped by. "It's hard for me to believe it's been a year," Wood said. For some of us, Sunday's anniversary may seem like a turning point — but it's really just one more day in the timeline of Japan's reconstruction. These pictures remind us that the work is far from finished.

The link to this story was "Japan's ground zero: Before, during and after". I'm wondering if the individual who listed it as such was aware of the history of that phrase. Hiroshima, Nagasaki? Ring a bell? Tacky.
You seem to blame USA for the "Ground Zero" Idea.
Japan was a deadly war machine in the days that caused the bombs to drop on them.
Japan was responsible for the killing of women, children and unarmed men in the millions, in China.
Japan also wanted to drop atomic bombs on California. Just a few more months and the US would have been ground zero, west cost.
@Gregcyber,
The USA has to take responsibility, for better or worse, for the "ground zero idea." We dropped the only atomic bombs with the sole intention of killing people.
1) We did not pick Nagasaki or Hiroshima because of their military significance. The Japanese military production was far dispersed for that. We chose the two cities because they had escaped thus far with relatively little damage, giving us a better opportunity to asses damage, especially to civilian populations.
2) The dropping of the atomic bombs was either necessary or important in ending the war. Curtis LeMay had taken fire-bombing by B-29's to such a level of perfection that every city, town, and village in Japan was pretty much doomed to being burned to the ground. The fire bombings caused much more damage and were far more effective than the atomic bombs.
3) The people in Japan were under a brutal and repressive military dictatorship. They were as much, if not more in some ways, a victim of the war. To say that a child killed in Hiroshima was somehow responsible for the death of women and children in China is simply faulty logic. While the Japanese are seriously racist, that it about it. Most of their actions resulted from a serious cultural paranoia for which there was no real cure.
4) When the a-bombs were dropped, very very little was known about the effects of radiation. The Japanese were fed a constant stream of bad information while being used by American scientists as guinea pigs to map and measure radiation effects. We wouldn't do that today. But it has left the Japanese people not only terrified of radiation, but extremely distrustful of government's involvement with such.
5) There was NO Japanese nuclear program. The Japanese long considered it technically impossible and spend virtually no effort toward it. The Germans, towards the end of the war, did try to forward to the Japanese some plans, equipment, and materials to be used for experiments with a-bombs, but the sub never made it. The Germans considered getting jet engine technology to the Japanese as very much more important since they also rated it as a minute chance of success within the next 100 years. They had no plans to even experiment with nuclear energy, let alone build bombs and certainly none to drop the non-existent weapons on California. There is no way to estimate how long it would have taken them because they had yet to take even the first step by the time the war was over.
6) The Japanese government and military was a large, arrogant, racist group who had absolutely no chance of prevailing in WWII. They were not so much a "deadly war machine" as a bunch of incompetents. They went to war without even having a decent infantry rifle or sidearm. They were so arrogant that they believed that these things were not necessary since any enemy would realize that they were fighting Japanese soldiers and just surrender immediately. That worked pretty well with Chinese peasants, and generals (such as MacArthur and Smiley) who were even more arrogant and incompetent, but failed immediately when the American GI entered the scene and kicked butt to the tune of a 7200:1 kill ratio.
In 1964 I was a young intelligence analyst assigned to the 544th ARTW. Our deputy commander was LtCol Kermit Behan, the bombardier on Bock"s Car. One night I pulled CQ with him and he discussed his involvement with the second atomic bomb. Some of what he said to me personally differed a great deal from what is written:
1) He felt no guilt about dropping the bomb. He dropped bombs on Japan all the time. This was only a matter of scale and a different type of bomb and nothing more. For a bombardier, it is a great deal more impersonal than you would thin. He is trying to make all sorts of calculations and fly the airplane while searching for his IP's and other landmarks. Not a lot of time for reflection, but rather training is what kicks in, not philosophical meditation as he thought that most people seemed to think.
2) Behan was very resentful, but understanding, that the atomic bomb had ruined his military career. He was an excellent bombardier/navigator but psychologists after the war determined that he was subject to an immense burden of guilt and so reported. His career languished while his colleagues waited for him to crack up. He was shufffled from flying (which he loved) to intelligence (which he didn't particularly like.)
3) Behan thought that the a-bomb had little, if anything at all, to do with the surrender of Japan. He was a B-29 guy and had been right in the middle of watching Curtis LeMay whip the cranky and difficult B-29 into reasonable shape and had watched as LeMay's fire-bombing of Tokyo and other cities proved incredible effective and devastating. In fact, many times more devastating that the atomic bombs.
4) Behan and most military planners of the day realized that an invasion of Japan was never going to happen BEFORE the atomic bombs were dropped. It was totally necessary. a) Much of the remaining Japanese Army was trapped in China, b) we had complete air superiority over Japan and had completely blockaded the seas around Japan, c) the fire-bombing would eventually have destroyed every city, town and village, forest, and most Japanese people in them. It would have been much less expensive than trying to inflict the same damage with a-bombs. d) Behan and other B-29 crews quickly figured out that there was no third atomic bomb waiting to be dropped. In fact, they quickly and correctly figured out that bomb #3 was likely more than six months away.
Mike, I agree completely, you beat me to it.
The listing must have been done by someone whose only concept of "Ground Zero" involves the World trade center in Manhattan. A sad commentary on the American Education System.
I reckon I'll change that, thanks for bringing it to attention.
Your photo's are misleading. The first three are of the damaged and under repair Daichi Nuclear plant which had the melt downs after the EarthQuake and tsunami. The 2004 pic is of the Fukushima Daini plant due south on the coast line from the Daichi plant. The Daini plant did have its problems after the quake but did not have near the problems that Daichi did.
To confirm, what stood out to me is the venting ducts on the roof of the rectangular buildings (sea side of the reactors) are in a straight line on the Diachi plant, The four white towers are in different locations in the first photos than in the last, and the sea walls are also inconsistent.
And to think that this was all caused by HAARP, right anne?
Or was it the dreaded chemtrails ?
You idiot!
