This image won Readers Choice in The Week in Pictures the week of May 8 - 15, 2008. This image of an electrical storm above a volcano was like nothing we'd seen, and as you know, we see, and often include, a variety of lightning and storm images in The Week in Pictures. This one blew the others away and was also included in the Year in Pictures.

Lightning bolts appear above and around the Chaiten volcano as seen from Chana, some 19 miles north of the volcano, as it began its first eruption in thousands of years, in southern Chile May 2, 2008. Cases of electrical storms breaking out directly above erupting volcanoes are well documented, although scientists differ on what causes them.
