A mud volcano may be the result of a piercement structure created by a pressurized mud diapir which breaches the Earth's surface or ocean bottom. Their temperatures may be as low as the freezing point of the ejected materials, particularly when venting is associated with the creation of hydrocarbon clathrate hydrate deposits. Mud volcanoes are often associated with petroleum deposits and tectonic subduction zones and orogenic belts; hydrocarbon gases are often erupted. They are also often associated with lava volcanoes; in the case of such close proximity, mud volcanoes emit incombustible gases including helium, whereas lone mud volcanoes are more likely to emit methane.
Approximately 1,100 mud volcanoes have been identified on land and in shallow water. It has been estimated that well over 10,000 may exist on continental slopes and abyssal plains.

The Indonesian natural resources are rich for its diversity in nature and culture. There are a lot of tourist spot; one of them is Bledug kuwu which is located in Purwodadi, central java.
This place is very unique; it is different from any other tourist object, it is named Bledug Kuwu. In United Stated there’s Salt Lake which came from the silting up of the sea and changed into land. In present time this land use as a testing place for the fastest vehicle in the world. It is different from the one that we have in Indonesia. It is also a nature wonder which no other countries have, it is called Bledug Kuwu. It is located in Kluwu village, kradenan district, Grobogan province. It is named Bledug Kuwu because of its sound that periodically make an explosion sound like Bledug (like an explosion of an artillery from the distance), from the mud bubble together with the coming out of the smoke, gases, and salty water. Through that process it became a land which it was from the bottom of the sea and now it became a mainland that reaches 53 meters height from the sea surfaces. The wide is 45 ha with the minimum temperature of 31° Celsius.
To be able to reach this place, we have to travel through the ground way from Semarang through Purwodadi until reaching the Kluwu village. During the journey we can see beautiful and fertile scenery of the nature, the spread of green rice fields and the blue sky. The beautiful view of the hills so fascinating so that the journey to this place won’t be quite boring, despite our eyes will be widely open and amaze by the scenery of the nature that green and amazing.
