Bulganak field of mud volcanoes, Mud volcano field in Lenine Raion of Crimea, Ukraine.
Bulganak field is a group of seven active mud volcanoes on the Kerch Peninsula that regularly eject gas and mineral-rich sediments. The volcanoes rise as cone-shaped mounds across the flat terrain, creating small craters and areas of bubbling mud.
The field has documented continuous volcanic activity since the 19th century, when scientists first systematically studied it. These early observations laid the foundation for understanding the geological characteristics of the entire Kerch Peninsula.
Local residents share observations of the eruptions through generations, documenting the sounds and changes in the landscape throughout different seasons.
The field is reachable by road from Kerch city and best explored on foot, with level and straightforward access throughout the site. Winter months offer the best chance to observe active mud emissions and gas releases.
The central mud dome, also called Central Lake, is the largest formation in the group and displays its own pattern of craters and pools throughout the year. The area of active mud surfaces changes noticeably with the season and rainfall.
