Barren Island volcano (India) - intermittent activity detected on satellite data

MODIS hot spot on Barren Island volcano (ModVolc, Univ. Hawaii)
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.
Without (the rare) direct observations (usually by Indian navy), it is impossible to know exactly what type of activity is going on at the moment. It could be intermittent strombolian-type explosions, and/or lava flows or even the formation of a small temporary lava lake.

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. ... Lees alle

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. ... Lees alle

MODIS hot spot data (past 7 days) for Barren Island volcano (ModVolc, Univ. Hawaii)
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. ... Lees alle

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. ... Lees alle

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.
