Berca Mud Volcanoes

The Berca Mud Volcanoes (Romanian: Noroioși de la Pâclele Mici) is a geological and botanical reservation located in Scorțoasa commune close to Berca in Buzău County in Romania.

As the gases erupt from 3000 metters deep towards the surface, through the underground layers of clay and water, they push up underground salty water and mud, so that they overflow through the mouths of the volcanoes, while the gas emerges as bubbles.

The mud dries off at the surface, creating a relatively solid conical structure resembling a real volcano.

The mud expelled by them is cold, as it comes from inside the Earth's continental crust layers, and not from the mantle.

The mud volcanoes create a strange lunar landscape, due to the absence of vegetation around the cones.
