Azerbaijan has more mud volcanoes than anywhere else in the world, anywhere from 350 to 700 of them at any given time. So what’s a mud volcano, you ask? It’s not a true igneous volcano as they don’t produce lava and are not necessarily driven by magmatic activity. They are instead created by the eruption of mud or slurries, water and gases that are formed by several different geological processes.
The people of Azerbaijan have different names for these fascinating geological phenomena, such as “yanardagh” (burning mountain), “pilpila” (terrace), “gaynacha” (boiling water) and “bozdag” (grey mountain).
