On the west side of the island is a caldera formed by an explosive eruption in the Pleistocene era.
Two kilometers wide, the caldera takes up the bulk of this tiny island that measures only 3 kilometers across. In this image, smoke blows from the volcano eastward over the Andaman Sea toward a bank of clouds.
The red outline indicates surface area hotter than its surroundings. Deception Island is one of the only places in the world where ships can sail directly into the center of an active volcano. Image of the Day Snow and Ice.
The plumes on that day were light gray to gray, and rose to around m. The NE portion of the island was covered with ash figure Eruptions in January-March and September January produce ash plumes, lava fountaining, and lava flows. Barren Island is a remote volcano east of India in the Andaman islands. Recent intermittent eruptions observed since have consisted of explosions, ash plumes, and lava flows. This report summarizes activity from January through January and is based on satellite data and observations.
Two main periods of eruptive activity are apparent figure 29 : the first in January-March , and the second in September January There are intermittent low-energy anomalies detected by MIROVA between these two periods but there are no indications of thermal anomalies in other datasets.
The anomalies with greater thermal energy in September-October correspond to lava flows on different flanks of the cone, as shown in Sentinel-2 thermal and visible satellite data figures 32 and From November through January there were intermittent thermal signatures and gas plumes from the crater visible in Sentinel-2 images.
The new eruption was first observed on 23 January , when a research cruise was working nearby. They witnessed explosions that produced incandescent material and small ash plumes figure 34 with the episodes lasting five to ten minutes.
The team noted ash plumes during the day and incandescent material being ejected onto the slopes at night. They observed four hours of activity before leaving the area.
The Indian Coast Guard also witnessed the eruption before 25 February, capturing a night-vision video of an explosion that produced an ash plume and ejected incandescent blocks above the crater that impacted the flanks of the volcano figure An overflight on 23 February was undertaken to assess the volcanic activity after several reports of activity over the previous days.
They observed intermittent explosions ejecting incandescent material and small ash plumes figure Activity consisted of ash plumes that rose a few hundred meters above the crater and the ejection of incandescent material every minutes, with blocks and bombs rolling down the flanks of the cone. Later in the month, an ash plume was observed on 24 March figure Along with the lack of activity detected in satellite data, there were no reports of activity after 24 March until September 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 These images coincide with Sentinel-2 thermal data showing a lava flow on the SSW flank.
A video taken on 27 October shows explosions ejecting incandescent material and small plumes. Darwin VAAC advisories noted ash plumes to about 0. Reference: Ray, D. Early activity of the Barren Island volcano: facts versus hype. Current Science, 9 : Thermal anomalies and small ash plumes during February-April and September January Barren Island is a remote stratovolcano located east of India in the Andaman Islands.
Its most recent eruptive episode began in September and has included lava flows, explosions, ash plumes, and lava fountaining BGVN This report updates information from February through January using various satellite data as a primary source of information.
There was a period of relatively low to no discernible activity between May to September Sentinel-2 thermal satellite imagery shows these thermal hotspots differing in strength from late February to late January figure The thermal anomalies in these satellite images are occasionally accompanied by ash plumes 25 February , 23 October , and 21 January and gas-and-steam emissions 26 April The maximum altitude of the ash plume occurred on 7 March, rising 1. Barren Island is a remote island east of India in the Andaman Islands.
Its most recent eruptive period began in September with volcanism characterized by thermal anomalies and small ash plumes BGVN This report updates information from February through July using various satellite data as a primary source of information.
The frequency of the thermal anomalies decreased during mid-May with only six detected between June and July Sentinel-2 thermal satellite imagery showed weak thermal hotspots in the summit crater on 5 and 10 February, and 5 April figure Intermittent gas-and-steam emissions were also observed in Sentinel-2 satellite imagery on days with little to no cloud coverage.
A small ash plume was observed in Sentinel-2 satellite imagery drifting NW on 24 June; there was no thermal anomaly detected that day figure It is the emergent summit of a volcano that rises from a depth of about m. 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.
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.

Photo Gallery An eruption in dramatically modified the morphology of the central scoria cone on the small Barren Island, one of the Andaman Islands, north of Sumatra. During the eruption the height of the cinder cone was reduced from to m, and the diameter of its crater increased from 60 to about m.
Two small scoria cones also formed in the lava field west of the main cone. Photo courtesy of D. Haldar, Geological Survey of India. Barren Island erupted for the first time in the 20th century in April Strombolian eruptions from the central cone produced ash plumes and incandescent ejecta, and a lava flow that is visible in the foreground and reached the W coast of the island. By the time of this 25 September photograph, all subsidiary vents had merged to form an enlarged summit crater.

GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano.
These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. Volcanic Hazard Maps The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers or other interested parties to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences.
In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes.
