Mud volcanoes are the national heritage of Azerbaijan. The territory of the state boasts almost half of all existing mud volcanoes on the planet. The people call them “yanardag” (blazing mountain), “pilpilya” (terrace), “gaynacha” (boiling water), “bozdag” (grey mountain).
Since the 19th century about 200 eruptions took place on the territory of the Azerbaijan Republic. The eruption of such volcanoes is accompanied by a strong explosion and underground roar. Gases come out from under the deep layers of the earth and immediately ignite. The height of the flame above such volcano sometimes reaches up to 1,000 meters.
NASA geologists, examining the hills on Mars, came to the conclusion: the mud volcanoes in Azerbaijan are very similar to those on the Red Planet. This natural phenomenon is included in the list of the Seven Wonders of the World by the International Competition of the Swiss non-profit organization.
Currently, the mud volcanoes in Azerbaijan are given the status of natural monuments and they are under the state protection. Mud, clay and volcanic waters are widely used in pharmacology and can cure various diseases.
