Recent Eruption of Mud Volcano in Andaman and Nicobar Islands

Overview

The mud volcano at Baratang in the Andaman and Nicobar Islands erupted after being dormant for over two decades. This event was marked by a loud sound similar to an explosion.

Details of the Eruption

• The eruption occurred on October 2, with a deafening sound.
• The mud volcano is driven by gases from decaying organic matter deep inside the earth, which push mud and gas to the surface.
• As a result of the eruption, an earth mound of 3-4 meters in height formed, covering an area of over 1,000 square meters.
• The area continues to emit mud and smoke, leading to a halt in tourist movement towards the site for safety reasons.

Location and Access

• Baratang is situated in the North and Middle Andaman district, about 150 km from Port Blair.
• The site is known for being India's only mud volcano, making it a popular tourist attraction.
• Authorities have informed local tourism stakeholders about the closure of routes leading to the site.

Safety Measures
