Tefala (Ile Tevala, Téfala, Île Tévala) is a small uninhabited island in the Pacific Ocean, belonging to the Shefa Province of Vanuatu. [1]

Geography

The island lies 2.6 km north-west of the small island of Laika, 9.4 km north of the island of Tongoa, and east of Epi. [2]

Geology

Tefala and other small islands scattered around Tongoa (Laika, Sail Rock) were once a part of a larger landmass formed by the eruptions of the submarine volcano of Kuwae in the second half of the 15th century. [3] The volcanic arc, called the New Hebrides arc, is home to a number of more famous volcanoes, such as Yasur, Gaua, and Ambrym. [4]

Mount Yasur Volcano on Tanna Island, Vanuatu

Mount Yasur is a volcano on Tanna Island, Vanuatu, 361 m (1,184 ft) high above sea level, on the coast near Sulphur Bay, northeast 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 several hundred years, although it can usually be approached safely. Its eruptions, which often occur several times an hour, are classified as Strombolian or Vulcanian. A large lava plain creeps across the valley at the base.
