mud volcanoes
Bubbling sediment vents
Mud volcanoes are geological formations where mud, water, and gases erupt from underground, creating cone-shaped mounds that resemble small volcanoes.
Unlike true volcanoes, they aren't driven by magma but by pressurized fluids and gases—often methane—pushing through sediment.
They range from inches to hundreds of feet tall and occur on land and underwater, sometimes in clusters.
