Located just 100 kilometres from the city of Port Blair. Lies the only live Mud Volcano in the whole of India called 'Jalki' by the locals. The mud volcano is one of the main tourist attractions for visitors travelling to the Andaman Island. But it is not an easy journey to witness this natural phenomenon. It takes at least a day of travel through the Jarwan Tribal reserve and across the sea at Baratang Jetty. Which is then followed by a 20 minute journey by road.

A mud volcano is created by natural gases emitted by underground decaying organic matter as the mud is pushed upwards by the gas. It hardens above the ground making it spill out over the edge as it grows in size. They are known to erupt in irregular intervals. The last one in 2005 is believed to have been caused by the 2004 Indian Ocean earthquake.
