This satellite image shows the billows of smoke hovering over West Russia. The smoke results from the devastating forest and peat fires during the summer of 2010. The fires were caused by a lasting heat wave that resulted from the so-called omega block. During this block, an extremely stable high developed over Russia. All in all, 30,000 sources of forest fires were registered, spanning an area larger than 1,2 million hectare.
