Great video of the Eyjafjallajökull volcano erupting. I suggest watching the video in full screen and watch for some spectacular lightning at the end during a plinian eruption (named after Pliny the Elder’s observations of Vesuvius burying Pompeii). This video was shot for British Channel 4 News. Blogger Dean Armstrong has been in that valley (Þórsmörk). (Yes, I have always wanted to use Þ (the letter thorn) in a blog post!).
