Azerbaijan is the global capital of mud volcanism: over 400 of the world's estimated 700 mud volcanoes are located here, making this small country one of the most geologically extraordinary places on Earth for subsurface fluid expression. Mud volcanoes are not the same as conventional volcanic systems — they are driven by pressurised gas (primarily methane) and water rising from deep petroleum-bearing formations, pushing a mixture of mud, water, and gas through fissures to the surface. The Gobustan plateau, southwest of Baku, concentrates the most accessible of these features: cones ranging from small bubbling pools to cones several metres high that periodically erupt, throwing mud tens of metres into the air. The mud itself — cool, grey, mineralised — has a consistency and sensory character entirely distinct from volcanic mud elsewhere in the world. Adjacent to the mud volcano field is the Gobustan Rock Art Cultural Landscape, a UNESCO World Heritage Site containing over 6,000 rock engravings spanning 40,000 years, from the Upper Palaeolithic to the medieval period, making Gobustan simultaneously one of the oldest and most active geological landscapes in the region.

The Gobustan Rock Art Cultural Landscape was inscribed as a UNESCO World Heritage Site in 2007, recognised for its extraordinary collection of prehistoric petroglyphs — images of humans, animals, boats, and symbols dating from the Upper Palaeolithic to the medieval period. The same landscape that bears these images of the earliest human inhabitants of the Caucasus also expresses one of the Earth's most active mud volcano fields — a juxtaposition of deep human time and deep geological time that is rare anywhere in the world.
The mud volcanoes of Gobustan are embedded in Azerbaijani cultural identity as evidence of the country's extraordinary geological wealth — the same petroleum-bearing formations that produce the mud also made Azerbaijan the world's first modern oil-producing country in the 19th century. Local tradition associated the mud volcanoes with the earth's breathing, with supernatural phenomena, and with the unpredictable generosity and violence of the subsurface. Baku's fire temples and eternal natural gas flames extend the same geological story across different cultural registers.
Gobustan National Park protects both the rock art and the mud volcano field under Azerbaijan's Law on Special Protected Natural Areas. The mud volcanoes are entirely natural phenomena and require no management intervention — they regulate themselves through the pressure cycles of the underlying petroleum system. The main conservation challenge is protecting the rock art engravings from weathering and from the increasing foot traffic of cultural tourism.
