Mount Yasur is a volcano on Tanna Island, Vanuatu, 361 m (1,184 ft) high above sea level,[2] 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.[1] 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.[3]

The glow of the volcano was apparently what attracted Captain James Cook on the first European journey to the island in 1774. Today, the mountain is a sacred area for the John Frum cargo cult. Members of the cult revere John Frum, a deified messenger who foretold the bringing of wealth to the island by American forces, and believe he resides in Mount Yasur with his countrymen.[4] The village of Sulphur Bay, the center of the movement, claims the volcano as part of their territory.

Access restrictions

Mount Yasur is an easily accessible active volcano, and is a major Vanuatu tourist attraction.[5] The Vanuatu Government monitors the level of volcanic activity in the interests of the public, both tourists and locals alike. This monitoring is carried out by the Vanuatu Geo-Hazards Observatory.[6]

The importance of the volcano to Tanna's tourism industry has resulted in the local government creating levels to alert people. These levels range from 0-5 and notes that An eruption may occur at any level[7]

• Level 0 - Normal
• Level 1 - Signs of Volcanic Unrest
• Level 2 - Major Unrest
• Level 3 - Minor Eruption
• Level 4 - Moderate Eruption
• Level 5 - Very Large Eruption

[es] Monte Yasur

El monte Yasur es un volcán activo de 361 metros de altura situado en la costa de la isla de Tanna en Vanuatu, cerca de la Sulphur Bay. El volcán está al sureste del monte Tukosmera, un volcán que estuvo activo en el Pleistoceno. Está compuesto de un gran cono piroclástico sin vegetación y un cráter casi circular de 400 metros de diámetro. Es un estratovolcán producido porque la placa Indoaustraliana, que se mueve hacia el este, se está deslizando bajo la placa Pacífica, que se mueve hacia el oeste. El volcán ha entrado en erupción continuamente desde hace siglos, aunque normalmente no es peligroso. Sus erupciones, que a veces ocurren varias veces en una hora, están clasificadas como estrombolianas o vulcaniana.
