Isla Barren

Barren Island

Estratovolcán · India · 354 m

An ash plume in 1991 rises above Barren Island along the volcanic arc connecting north of Sumatra. The 3-km-wide island contains a 1.6-km-wide crater that is partially filled by a scoria cone that has been the source of eruptions since the first was recorded in 1787. Lava flows reached the coast during several recent eruptions.

Resumen geológico

Barren Island, a possession of India in the Andaman Sea about 135 km NE of Port Blair in the Andaman Islands, is the only historically active volcano along the N-S volcanic arc extending between Sumatra and Burma (Myanmar). It is the emergent summit of a volcano that rises from a depth of about 2250 m. The small, uninhabited 3-km-wide island contains a roughly 2-km-wide caldera with walls 250-350 m high. The caldera, which is open to the sea on the west, was created during a major explosive eruption in the late Pleistocene that produced pyroclastic-flow and -surge deposits. Historical eruptions have changed the morphology of the pyroclastic cone in the center of the caldera, and lava flows that fill much of the caldera floor have reached the sea along the western coast.

Resumen de Wikipedia

Barren es una isla que se encuentra en el mar de Andamán, siendo una de las más orientales de las islas Andamán. Es además el único volcán activo conocido en el sur de Asia.[cita requerida] Junto con el resto de las islas Andamán, es parte del territorio indio Unión de Andamán y Nicobar. Se encuentra a unos 135 kilómetros al noreste de la capital del territorio, Puerto Blair. La primera erupción registrada del volcán se remonta a 1787. Desde entonces el volcán ha hecho erupción más de diez veces, siendo la más reciente la que se produjo en mayo de 2008.
