Points to Remember
|
|
|
- The Barren Island, about 140 km from Port
Blair, is a tourist destination and surrounded by waters ideal for scuba
diving and is home to a wide variety of aquatic life.
- The island is open to visitors, with
prior permission, and as the name suggests is uninhabited and devoid of any
significant vegetation.
- It’s the only active volcano along a
chain of volcanoes from Sumatra to Myanmar.
- The 354-metre-high island is the emergent
summit of a volcano that rises from a depth of 2,250 m.
- In 1991, it spewed so massively that
smoke billowed out for about six months.
- Ever since, there have been eruptions
every two-three years, the last in February 2016.
- In 1991, the volcano’s eruption was
catastrophic for several animal species.
- The eruption reduced the number of bird
species and their population. Of the 16 previously reported species, only six
were observed, of which the Pied Imperial Pigeon (Ducula bicolor) was the
most abundant. A night survey encountered only one rat species (Rattus
rattus) and 51 species of insects from eight orders.
