Mud Volcano Erupts After Two Decades in Andaman | 18 Feb 2026

Why in News? 

A mud volcano that had been dormant for more than two decades erupted unexpectedly at Shyamnagar in Diglipur in North Andaman, causing thick mud and gas to be released from the ground. 

Key Points: 

• Geological Significance: Mud volcanoes are geological formations that expel mud, gas, and water due to underground pressures and fluid movements, and are distinct from conventional lava-spewing volcanoes. 
  • Location: The mud volcano is located near Jal Tikrey in North Andaman’s Diglipur, a region known for its chain of mud volcanoes set amid green forest landscapes. 
• Monitoring: The unexpected activity has attracted geologists who are likely to monitor the site more closely to understand underground processes and fluid dynamics beneath the islands. 
• Impact: Local authorities have taken precautionary measures by restricting public access to the eruption site to ensure safety, though no major injuries or structural damage have been reported.  
  • Experts note that mud volcano eruptions are generally linked to tectonic activity and underground pressure rather than external climate factors, and such events can provide insights into regional geology.
