India’s only active volcano, Andaman and Nicobar, Barren Island
Andaman and Nicobar Island, Volcano: it is said to be India’s only active volcano in the Andaman and Nicobar Islands. This Volcano last erupted in 1991 after lying dormant for 150 years, has started spewing smoke and lava. Is active once again.
The Barren Island volcano has been showing spordaic activity. Scientist of Goa-based National Institute of Oceanography said.
Currently the Volcano is erupting at a interval of 5 to 10 min. During the day, only as clouds were observed. But after sundown, red lava foundation was spewing from the crater into the atmosphere and hot lava streamed down the slopes.
The site was later revisited by B Nagender Nath and his team, where they witnessed the continuation of spruts of blasts and smoke.
The Andaman basin is known for its strong seismicity and any submarine volcanoes. 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.
How are these volcanoes formed: These Volcanoes are formed due to the rising magma formed deep in the mantle due to the melting of the subducted Indian Ocean crust.
The Volcanic island is uninhabited and the northern part if the island is, as the name suggests is barren and devoid of any vegetation. Indian citizen can visit the volcanic island by charted boats after obtaining permission from the forest department of Port Blair.
