Researchers at the Goa-based National Institute of Oceanography (NIO) on Friday stated that India’s only live volcano has become active again after lying dormant for more than a century.

The discovery was made – when a scientific team on board CSIR -NIO’s research ship which was collecting sea floor samples in the Andaman Basin – near the Barren volcano when the dormant volcano suddenly started spewing ash.

“The only live volcano in the Andaman and Nicobar islands is erupting once again. The Barren Island volcano, located 140-km north-east of Port Blair, dormant for more than 150 years started erupting in 1991 and has since then shown intermittent activity,” CSIR-NIO said in their statement.

While in the daytime, only ash clouds were visible, red lava fountains erupted after sundown and streams of hot lava trickled down the slopes.

“They have sampled the sediments and water in the vicinity of the volcano and recovered coal-like black pyroclastic material representing proximal volcanic ejecta. Clouds were seen at the crater mouth where the smoke was bellowing out in otherwise clear sky,” researchers said.
