Ash and steam plume from Barren Island on 16 Nov (Landsat 8 image, annotated by Culture Volcan)
With all likelihood, the volcano continues to be in eruption. It is very remote and rarely directly observed, but satellite imagery regularly show albeit weak thermal signals - again present more or less continuously since August and more frequent since October this year. ...more

MIROVA thermal signals of Barren Island volcano
An ash plume was reported this morning, at estimated 5,000 ft (1.5 km) altitude, extending 50 km to the east from the island (VAAC Darwin). This suggests that a new phase of activity is occurring at the volcano. ...more

Hot spot at Barren island (MIROVA)
A steam and ash plume at estimated 10,000 ft (3 km) altitude and extending 35 km to the east from the volcano was detected yesterday on MTSAT satellite imagery (VAAC Darwin). ...more

A pilot reported an ash plume rising to 10,000 ft from the volcano. Likely, eruptive activity which had produced a new lava flow in March is still going on or has resumed.
Sun, 5 Apr 2015, 11:05
An eruption occurred in mid to late March with strombolian explosions and the effusion of a lava flow from the central cone.

Hot spot detected at Barren Island via MIROVA
As the Culture Volcan
blog pointed out, a weak thermal anomaly was detected on satellite data above the volcano yesterday. The hot spot is weak, but could indicate some sort of activity occurring at the volcano. What could be a plume is visible on other satellite imagery, but for now, there is no confirmation of volcanic activity.

Gas and ash plume from Barren Island today (MODIS/Terra, NASA)
Intermittent eruptive activity continues on the small remote island next to the Andaman island group. A small steam and ash plume and a thermal hot spot can be seen on today's and yesterday's satellite images. ...more

MODIS hot spot data (past 7 days) for Brren Island volcano (ModVolc, Univ. Hawaii)
A significant thermal anomaly remains present at the volcano which is likely in some sort of eruptive activity (lava flows?). However, no plumes could be detected on satellite imagery. An aerial survey by the Indian Navy could give more clues what is going on.

MODIS hot spot data (past 7 days) for Barren Island volcano (ModVolc, Univ. Hawaii)
New and relatively strong thermal signals are visible on satellite data. They suggest renewed (or increased) activity, perhaps in the form of lava flows.
Thu, 17 Oct 2013, 11:20
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).

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.
