Ash from Puyehue Volcano Off Coast of Argentine Patagonia43.5S 60.4W
Ash from the 2011 Puyehue volcanic eruption, which began in early June, can be observed off the coast of Argentine Patagonia in this image acquired in mid-August. In the full image, a light veil of ash can be seen further to the north, east of the Uruguay-Brazil border.
By June 18th the ash cloud had completed its first circle of the globe. An estimated one hundred million tons of ash, sand and pumice were ejected – requiring power equivalent to 70 atomic bombs.
