This photo of Mount Redoubt, caught in mid-eruption, was taken from a height of 423 miles, on March 30, 2009 as the GeoEye-1 satellite moved from north to south over Alaska at a speed of 4 miles per second. Since the amount of area is so large, the ground resolution of this image is 2 meters.

The media is paying relatively little attention to this volcano, just as they're ignoring the rumblings under the Yellowstone Caldera. Yellowstone experienced a swarm of quakes at the end of 2008, and geologists are still scratching their heads about what it all means. More could be done in piecing the puzzle together and letting people know what to expect down the road. TheCityEdition.com has a 2012 Survival Guide online (if anyone's interested) that links to the Alaska Volcano Observatory and other disaster monitoring sites.
In response to "notrocketscience" comment RE Mt Redoubt article. Most people, it seems to me, are blissfully happy to neither know nor understand any of the particulars on ELE topics such as the Yellowstone caldera (and others).
By the by, "survival guide"?! You're not serious, are you? I'm no apocalyptic, armegedon now, soothsaying, end-of-the-world propheseer, but there IS a pretty darn good reason these phenomena are called "Extinction Level Events". The only way you're surviving any of these cataclysms is by being on a fully self-reliant interplanetary craft far enough out to avoid even a Nova and yet be able to either a) return afterward to repopulate the world, or b) head out into deepspace in hopes of some future generation finding a new homeworld. Unless this "survival guide" has info relating to such specifics, I don't believe it'll be of much use to 6 billion+ crispy critters. But that's just me. Hey, I'm just sayin'.
Very nifty photo, it will be interesting to see what happens here. Also, I believe the picture above is not oriented correctly. It needs to be rotated 90 degrees clock wise. What is suppose to be "south" is facing "east".
