Barren Island is an island located in the Andaman Sea.It is the only confirmed active volcano in South Asia, and the only active volcano along a chain of volcanoes from Sumatra to Myanmar. Report on Barren Island (India) (Krippner, J.B., and Venzke, E., eds.).

About Barren Island: The barren island has been estimated to be 1.8 million old.
While the first indications of a new eruptive in thermal data is on 24 September, the first observations on the 18 and 19 October show lava fountaining at the summit and a lava flow on the flank (figures 38, 39, and 40). Twenty-one people were killed, including two who are missing and declared dead, and a further twenty-six people suffered injuries, many of whom suffered severe burns. Source: Darwin Volcanic Ash Advisory Centre (VAAC), Smithsonian / USGS Weekly Volcanic Activity Report, Eruptions, Earthquakes & Emissions Application, Darwin Volcanic Ash Advisory Centre (VAAC). They witnessed explosions that produced incandescent material and small ash plumes (figure 34) with the episodes lasting five to ten minutes.

From November 2018 through January 2019 there were intermittent thermal signatures and gas plumes from the crater visible in Sentinel-2 images. Bulletin of the Global Volcanism Network, vol. Zudem registriert MIROVA eine thermische Strahlung in Höhe von 53 MW. On 9 March 2017 a group from the Physical Research Laboratory in Ahmedabad observed the eruption and published a report in Current Science (Ray et al., 2017). 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. Data is reported through the last data update (17 September 2020).

A stop date with "(continuing)" indicates that the eruption was considered to be ongoing as of the date indicated. 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. Barren Island recent eruption: India’s only active volcano — the Barren Island volcano (Stratovolcano) — in the Andaman and Nicobar Islands is again spewing lava and ash. 2 (February 2019) Global Volcanism Program, 2019. A video taken on 27 October shows explosions ejecting incandescent material and small plumes. 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.
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). Barren Island volcano ist der einzige aktive Vulkan Indiens. Februar 2019 von Marc Szeglat. Report on Barren Island (India).
The anomalies with greater thermal energy in September-October 2018 correspond to lava flows on different flanks of the cone, as shown in Sentinel-2 thermal and visible satellite data (figures 32 and 33).
Barren Island (India) Eruptions in January-March 2017 and September 2018-January 2019 produce ash plumes, lava fountaining, and lava flows. There are intermittent low-energy anomalies detected by MIROVA between these two periods but there are no indications of thermal anomalies in other datasets.
), Weekly Volcanic Activity Report, 30 January-5 February 2019. Volcano Profile | These times coincide with the highest frequency of thermal anomalies detected by the MIROVA algorithm (figure 30).
The new eruption was first observed on 23 January 2017, when a research cruise was working nearby.
