They emerge as a result of natural gases (methane) eruption, post-volcanic emanations (solfatara and fumarole) and seismic impact. Mud volcanoes which erupt due to natural gas eruption. They result from emanations of gas released from store-rocks situated at various depths. In its way to surface, the gas carries fresh or salt water, which softens and weathers the encountered rocks and soil layers, bringing them to surface along minimal resistance lines. This type of mud volcanoes are to be found in Russia, Italy, North Iran and Iraq, India and Burma, in the south of the USA, Venezuela, Colombia, Romania. In Romania, they are located in the Transylvanian Depression (Cluj, Alba, Sibiu and Mures counties), the Moldavian Plateau(Iasi county), in Gorj Subcarpathians and in Buzau Subcarpathians .
