I like this one. It is from NASA though I’ve heavily hacked it around (I saw it today in a copy of Wired at Mr Polito’s; oh yes, it is online too: http://www.wired.com/wiredscience/2009/08/gallery_volcanoes/3/, but I don’t recommend visiting, the site is mindbogglingly slow, lord knows how much Javash*t they load up). Anyway, it’s the Sarychev volcano (Russia’s Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009. I’m not entirely sure what I’m seeing here – real Met Men should comment – or how tall the plume is. Is it hitting the stratosphere?
