The Mud Volcanoes of Pâclele Mici are a protected area of ​​national interest corresponding to the IVth category of the IUCN (natural reserve, botanical and geological type) located within the Berca commune of Buzău county.[2][3] Pâclele Mici is located in the central area of ​​the Berca depression[4] at an altitude of 341 m and has an area of ​​16.5 ha. The main characteristic of these volcanoes is the different height of the cones, reaching 7-8 m but the craters are smaller and are called Pâclele Mici.[5] During heavy rainfall, the eruption of the volcanoes here increases and causes mudflows to start downstream, sliding especially towards the southern side, where the "badlands" were born.
