Torfajökull (Icelandic for "Torfi's glacier"; Icelandic pronunciation: [ˈtʰɔrvaˌjœːkʏtl̥] ) is a rhyolitic stratovolcano, with a large caldera (central volcano) capped by a glacier of the same name and associated with a complex of subglacial volcanoes. Torfajökull last erupted in 1477 and consists of the largest area of silicic extrusive rocks in Iceland. This is now known to be due to a VEI 5 eruption 55,000 years ago.
