Just as you predicted.
THIS REPORT TURNED OUT TO BE WRONG.
BARREN ISLAND IS NOT ERUPTING.

"The Geological Survey of India describes the Baratang crater as a mud volcano covering an area of about 1,200 square metres (1,440 yards), which has been increasing in size from a minor fissure."
"Official sources earlier mistakenly sited the volcano on Barren Island, site of a crater traditionally known as the only active volcano in India."
Mud volcanoes aren't "real" volcanoes. They aren't listed as such on volcano websites, etc. They're caused by naturally escaping natural gas from oil formations, etc.
