The eastern most point of the Andaman Islands has a great specialty, the location of the only active volcano in south Asia is here and it is known as the barren islands. The distance between the barren islands and the capital of Andaman and Nicobar (Port Blair) is around 135 kms.The barren island comes under the Indian union. The first eruption in the barren islands had taken place in the year 1787. After the first eruption almost 10 eruptions were reported till date. The later eruptions had taken place in the following years; 1789, 1795, 1803, 1852, 1991, 1994, and 2004. As we go through the years of eruption, we could find that there was a great time gap between the eruptions of 1852 and 1991; this shows that this volcano remained dormant for more than a century.As per the latest news the recent eruption was started on September 2014 and it is still continuing.
The presence of other volcanoes in this region makes it clear that it is located in volcanic zone. Narcondum is another which is present in this area. The island is located on the edge of the Indian and Burmese tectonic plates which is in the middle of a volcanic belt. The highest point in this island is around 354 meters above sea level. Tourists perform scuba diving and snorkeling in the waters surrounding this Island. Another great significance of these waters is that it is very clear. The total length of the island is around 3 km long and its caldera is around 2 km wide. Human inhabitant is not there in the Barren Islands. But some animals like bats, birds and some rodents like rats which can survive harsh conditions, live here. The last eruption of 2005 was initiated by the great Sumatra earth quake.
