Chile's Calbuco volcano erupted twice within 24 hours yesterday and the pictures are stunning. This is the first time the volcano has erupted in more than 42 years. See more photos from the Wall Street Journal here, and a time lapse video from The New York Times here. I've always been fascinated by volcanoes -- I wrote a short post about Susan Sontag's The Volcano Lover when Iceland's Eyjafjallajökull erupted in 2010, and you can see Mount Etna in the background of some of my pictures from Sicily. Time Magazine ranks Mount Vesuvius near Naples number one in a list of the top 10 most famous volcanoes (I'm not the only enthusiast), and someday I would like to peer into the stratovolcano that buried the cities of Pompeii and Herculaneum in the year 79.
