Barren Island, India's only active volcano, roared again. On the desolate island of the Andaman and Nicobar archipelago, two mild eruptions took place on September 13 and 20. This island is about 140 kilometers from Port Blair. The Indian Navy has also made a video. Currently, there is no threat to the surrounding areas. However, the region did experience an earthquake of 4.2 magnitude in Andaman as a result.
Barren Island is a small island in the Andaman Sea, wholly volcanic in nature. No humans reside here, only wild animals and birds. This is India's sole active volcano, formed by the collision of tectonic plates beneath the Bay of Bengal. The island rises 354 meters above sea level. It is a significant research center for scientists.

The first eruption occurred on September 13, emitting smoke and ash, followed by a second eruption on September 20. These were 'Strombolian' type eruptions, which are mild yet persistent. Activity was also observed here in July 2025. The Darwin Volcano and Ash Advisory Centre (VAAC) noted ash plumes from July 30 to August 5. However, these eruptions are mild enough not to affect air travel or nearby islands.
The Indian Navy recorded the eruption on September 20, showcasing a river of lava flowing. Officials stated that monitoring is ongoing, but there is no warning issued for Port Blair or adjacent areas.

This volcano was first recorded in 1789 and has continued to erupt sporadically since. A significant eruption occurred in 1991, with lava flowing far. It remained active in 2017 and 2018. Scientists state that the volcano is located in a 'subduction zone,' where the Indian plate is sliding under the Burma plate.

This process brings magma to the surface, causing eruptions. Visiting the island is challenging due to it being a protected area. Tourists are not allowed, but scientists conduct studies. Rare birds like the Barren pigeon are found here.
The eruptions are mild, but prolonged exposure to ash can affect nearby marine life. Fish and coral reefs might be endangered. Ash poses a threat to air travel, but flights are currently safe. Climate change could heighten volcanic activity, but Barren Island faces no significant threat for now. The Geological Survey of India (GSI) and the Navy are monitoring the situation. If eruptions intensify, warnings will be issued.

India has few volcanoes, making Barren Island unique. It aids scientists in understanding Earth's internal activities. The name 'Barren' stems from the English word for barren or deserted, as nothing grows here. However, it symbolizes the might of nature. These eruptions remind us of how vibrant our planet is.
