Barren Island volcano (India): eruption continues, strombolian activity

The volcano remains active as a satellite image from earlier today shows. A small ash plume can be seen which suggests that the volcano is in a phase of intermittent small strombolian-type explosions.
Thermal signals of the uninhabited island are weaker than a month ago, and limited to the area of the cone. This indicates that there are currently no more active lava flows (or limited to the immediate surroundings of the cone).

The mainly effusive eruption of the volcano continues. Recent satellite images show an active field of fresh lava flows towards the northwest form the active cone. ... [meer...]

Tuesday, Oct 02, 2018
A new eruption seems to be going on at the remote island (the only active volcano of India): since around 25 Sep, a strong thermal signal has been visible on satellite data and suggests lava flows on the north flank of the active cone, probably reaching the NW coast. [meer...]

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.
