Thursday, Oct 17, 2013
Eruptive activity continues. An ash plume was spotted on satellite imagery this morning rising to 12,000 ft (3.6 km) and drifting 15 nautical miles to the NW (VAAC Darwin).

A new eruption occurred this week. This was confirmed by the Indian Navy (via twitter) who reported "smoke" and lava seen on the island from a surveillance plane. A large hot spot is visible on recent MODIS satellite data on the remote volcanic island, located in the Andaman Islands archipelago. ...more [read all]

A new eruption seems to have started. An ash plume rising to 20,000 ft (6 km) altitude and drifting 120 nautical miles to the SW was reported last night by VAAC Darwin. The aviation color code was raised to RED.

Based on pilot observations, the Darwin VAAC reported that ash-and-steam plumes from Barren Island on 19 and 20 October reached altitudes of 1.5 km (5,000 ft)a.s.l. and drifted WNW.

Indian Coast Guard officials noted in a news report on 23 September that the continuing eruption at Barren Island was decreasing in intensity. A surveillance report stated that there was less lava but more "smoke" coming from the volcano.

Based on a pilot report, the Darwin VAAC reported an ash plume from Barren Island on 26 May that reached an altitude below 3 km (10,000 ft) a.s.l. and drifted N at 1230.

Barren Island remains active. Pilots frequently observe ash plumes at around flight level 100. The volcano continues to emit small to moderate amounts of ash forming plumes travelling beneath 10-15000 ft (ca. 3-4,5 km a.s.l.) and extending for about 20 nm (30-35 km). -->More on Barren Island

The volcano on Barren Island is still very active as news reports. The height of the cone has increased by about 50 metres during the past nine months since its eruption started last May. A team of scientists from India landed on the island to study the recent eruption. Lava flows have covered the entire north-western face of the island destroying the lone landing site. ->More on Barren Island

According to Indian news sources, the eruption is going on and has intensified. Lava fountaining, and strombolian explosions are ejecting material to up to 100m above the new vent, which has formed at the SW rim of the existent crater and might construct a new cone.

The eruption at Barren Island continues with moderate strombolian activity. According to the Indian press, the authorities of the Andaman islands are planning to arrange organized sight-seing boat trips to Barren Island in order to give tourists the unique opportunity to watch Inddia's only active volcano from the sea, as long as the eruptino still continues. The cost of the overnight-trip from Port Blair, about 140 away has yet to be fixed.

After no observation was possible for some days due to heavy monsoon rains, it has been confirmed that the eruptino is continuing. Pilots from aircraft have observed small lava fountains and ash plumes.

India's only active volcano, the tiny uninhabited Barren island in the Dec. 2004 tsunami-hit Andaman and Nicobar archipelago has started an eruption as news reports state after an Indian coast guard ship had sighted a thick plume of smoke.
Background: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-trending volcanic arc extending between Sumatra and Burma (Myanmar). The 354-m-high island 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. The morphology of a fresh pyroclastic cone that was constructed in the center of the caldera has varied during the course of historical eruptions. Lava flows fill much of the caldera floor and have reached the sea along the western coast during eruptions in the 19th century and more recently in 1991 and 1995.
