What is a Mud Volcano Landform?

A mud volcano is a formation created by the ejection of mud from the ground. A mud volcano is not a true volcano and no lava or ash are produced.




How are Mud Volcanoes Formed?

Ground water is heated by geothermal activity and mixes with sediment to form mud. Steam from heated water deep underground forces mud through an opening or fissure in the ground, sometimes in a fault zone. A mud volcano called Lusi in Indonesia may have been artificially created while drilling for gas. An earthquake occurred and a large mud flow was produced which killed 14 and destroyed the homes of 24,000 other people.

How Large is a Mud Volcano?

A small mud volcano may be only a few feet high and wide. The largest is Lusi in Indonesia and is 6 miles wide, reaching 2300 feet in height.

Where Can a Mud Volcano Be Found?

A mud volcano can occur in a fault zone, an area of volcanic activity or in a subduction zone under the ocean.
