The eruption in 1991 occurred after about 50 years of dormancy and became the focus of a lot of scientific researches and discussions. This eruption continued for a few months and caused a lot of damage to flora and fauna all around.
Barren Island as the name suggests is a barren or deserted area and is not inhabited by human beings. But this island is known to shelter a small-size goat population and also bats, birds and rodents that have managed to survive in the extremely harsh conditions.

Barren Island volcano was recently in news for being active, spewing a lot of lava and ash. The Island was visited by a team of scientists belonging to the National Institute of Oceanography from Goa. These scientists have rested all apprehensions calling the fulmination of the volcano to be benign. There were short eruptions lasting 5 to 10 minutes. Ash clouds were spumed in daytime while red hot lava fountains were ejected from the crater after sunset. After sampling the sediments, scientists have recovered black pyroclastic material like coal. Repeated scientific expeditions were planned to ascertain the ecological impact of volcanic activity.
The Island is about 3 kilometres wide and has a crater measuring 2 kilometres that has walls surrounding it as high as 250-350 metres high. For the last recorded eruption, the Explosivity Index was 2 on a scale of 1 to 8, which is rather low. The eruption of 1991 proved catastrophic and reduced the number of animal and bird species.
