There are 12 photos available for volcanoes in India.

An eruption in 1991 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 305 to 225 m, and the diameter of its crater increased from 60 to about 200 m. Two small scoria cones also formed in the lava field west of the main cone.

The main crater was active and both explosive and effusive activity had shifted to the N. Two incandescent lava flows are visible along the slopes of the scoria cone, and steam-and-gas plumes mark the entry point of the lava flows into the sea.

Photo by A. Kar, 2005 (Central Ground Water Board). The lava delta extending across the photo formed during the 1994-1995 eruption of Barren Island. The eruption was first noticed by the Indian Navy on 20 December 1994. Explosive activity was observed from satellite images and during visits from January to March and May 1995. Four vents were active from the summit to the S flank of the cone along a N-S south line. A new vent was observed on 11 May on the W flank of the cone that produced a lava flow.

Both volcanoes are part of the Andaman and Nicobar Islands of India in the Andaman Sea, and are part of a volcanic arc extending from Sumatra. The small 3 x 4 km wide island, located about 130 km E of North Andaman Island, is densely vegetated and has three peaks. No evidence of historical volcanism is present.

Photo published in Shanker et al., 2001 (courtesy of D. Haldar, Geological Survey of India). Barren Island erupted for the first time in the 20th century in April 1991. 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.

The flow entered the sea at two points following the routes of the previous 1991 and 1994-95 lava flows. A plume from the summit crater of the central scoria cone is visible to the upper right, along with an active lava channel descending the flanks.

The 3-km-wide island contains a 1.6-km-wide crater that is partially filled by a scoria cone that has been the source of eruptions since the first was recorded in 1787. Lava flows reached the coast during several recent eruptions.

The 1991 eruption, the first of the 20th century from Barren Island, included explosive activity from a vent on the upper NE flank and lava flows that reached the west coast of the island.

Incandescent ejecta and an ash plume from Strombolian eruptions that began in April 1991 are seen in this 16 May 1991 view of the scoria cone in the center of Barren Island. The 1991 eruption was the first from Barren Island in the 20th century.

Raina, 1991 (Geological Survey of India) Light-colored volcanic ash from the 1991 eruption mantles the surface of a lava flow from the same eruption, and the scoria cone in the center of the photo. The slopes of the central cone, the source of the ashfall, is the larger feature to the right.

Prior to the 1991 eruption, the central scoria cone in the crater of Barren Island was 305 m high with a 60-m-wide crater at its summit. The black lava flow in the foreground erupted during 1803-1804 and extends from the base of the cone to the west coast. This lava flow was the first known in historical time from Barren Island.

Photo courtesy of D. Haldar, 1990 (Geological Survey of India). Barren Island is shown erupting on 28 May 2005 from the WNW. The black lava flow in the foreground is from the 1994-95 eruption. A lava flow is being extruded from a flank vent below the white plume. Eruptions that began on 26 May occurred from the summit of the scoria cone as well as flank vents. Lava flows later reached the W coast along the same path as flows from the 1991 and 1994-95 eruptions.
