Mud Volcano

Context: A Mud Volcano eruption was recently reported in Diglipur, Andaman Islands, drawing attention to this rare geological phenomenon in India.
What is a Mud Volcano
- A mud volcano is a mound of mud pushed upward through overlying sediments.
- It forms when mud, gases, and water erupt to the surface from underground layers.
- Unlike magmatic volcanoes, it does not erupt lava. Instead, it releases mud, slurry, steam, and gases.
- Some eruptions can be forceful, even throwing flames due to gas ignition.
- Formation Mechanism
- Some mud volcanoes form due to hot spring activity. Gas and water react with rocks, producing boiling mud.
- Under compactional pressure, methane and hydrocarbon gases push mud upward, causing eruptions.
- The erupted mud may be hot and sometimes accompanied by steam emissions.
- Distribution
- Mud volcanoes occur on land and seabeds. Submarine eruptions may form islands or banks.
- Around 1,000 mud volcanoes have been identified globally.
- In India, the only known mud volcano is located at Baratang Island in the Andaman and Nicobar Islands.
