Picture of the day for November 26, 2017

picture of the day on November 26, 2017: The Berca Mud Volcanoes are a geological and botanical reservation located close to Berca in Buzău County, Romania. The phenomenon is caused due to gases that erupt from 3,000 metres (9,800 ft) 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 as you can see in the image. http://ift.tt/2n0lwt6
