Mount Yasur

Mount Yasur is an active volcano on Tanna Island, Vanuatu (lat/long 19.52 S, 169.43 E) with a height of 361 m (1,184 ft) above sea level, located on the coast near Sulphur Bay. It lies to the southeast of the taller Mount Tukosmera, which was active in the Pleistocene. It has a largely unvegetated pyroclastic cone with a nearly-circular summit crater 400 m in diameter. It is a stratovolcano, caused by the eastward-moving Indo-Australian Plate being subducted under the westward-moving Pacific Plate. It has been erupting nearly continuously for centuries, although it can usually be approached safely. Its eruptions, which often occur several times an hour, are classified as Strombolian or Vulcanian.
