Mud Volcanoes of Andaman Islands
A mud volcano is formed by emission of de-pressurized pore water and natural gases (mainly hydrocarbon gases like Methane) emitted by decaying organic matter underground. The gases at times are emitted with loud explosion and associated with fire flares. As the mud is pushed upwards by the gas, it deposits and hardens above the ground. As more mud oozes out and spills over the edge it grows in size, gradually forming a miniature volcano with rich, creamy mud crater at the top.

More than 25 Mud volcano sites are discovered at Andaman Islands as early as 1954 and scattered between North and South Andaman. As per available information the first observed mud volcano explosion was observed in March 1983 in Nilambur Village in Baratang Island. Since 2003 both
and Baratang mud volcanoes started exploding and emitting mud and gas. Gas Entrapment funnels are placed at Baratang Jarawa creek site by Department of Atomic Energy to monitor the Hydrocarbon levels.
