Volcano in the Andaman and Nicobar Islands has beome active and 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.
A team of scientists led from CSIR-National Institute of Oceanography (CSIR-NIO) in Goa reported that the volcano is active and spewing smoke and lava once again.
During the daytime only ash clouds were observed. However, after sundown, the team observed red lava fountains spewing from the crater into the atmosphere and hot lava flows streaming down the slopes of the volcano.
The Andaman Basin is an active back-arc spreading basin and is known for its strong seismicity and many submarine volcanoes and hydrothermal activity.
Scientists from CSIR-NIO have been surveying the Andaman Basin and they have identified many small submerged volcanoes in a linear chain called a volcanic arc. These volcanoes are formed due to the rising magma formed deep in the mantle due to the melting of the subducted Indian Ocean crust.
A few of these submarine volcanoes have been dredged for samples and pumice type of light volcanic rock have been recovered.
The volcanic island is uninhabited and the northern part of the island is, as the name suggests, barren and devoid of vegetation.
