What are mud volcanoes?
A mud volcano is a landform created by the eruption of mud or silt, water, and gases. Mud volcanoes do not produce lava.
The Mud Volcanoes of Berca, Romania are formed due to the accumulation of natural gases, mainly methane, below the Earth’s surface. The pressure builds up over time, forcing the gas, along with water and mud, to escape through vents in the ground. Mud ejected during these eruptions solidifies when exposed to air, creating cone-shaped structures.

How many mud volcanoes are there on Earth?
About 1100 mud volcanoes have been identified on Earth. Mud volcanoes may also exist on Mars.
Other mud volcanoes can be found in Russia, Ukraine, Bulgaria, and Italy but also in other countries.
The Berca Mud Volcanoes are second in size in Europe, after those of the Apseron-Baku Peninsula in Russia.

Are mud volcanoes dangerous to visit?
While mud volcanoes are generally not considered dangerous, visitors should be cautious, especially around active vents where mud and gas are being expelled. It is advisable to stay on designated paths and avoid approaching active mudflows. In addition, wearing appropriate footwear and prior information about the weather conditions are important things.
