Mud volcanoes in Azerbaijan

Mud volcanoes are a distinctive natural phenomenon in Azerbaijan, formed by the release of pressurized gas, water, and mud from deep within the Earth's crust. About 200 eruptions have occurred at 50 volcanoes in the region since 1810. These eruptions are accompanied by powerful explosions and underground rumbling. Gases emerge from the deepest layers of the Earth and often ignite immediately, with flames reaching up to 1,000 meters at the Garasu volcano. The Toragay volcano erupted six times between 1841 and 1950. Volcanic mud is used as a raw material in the chemical and construction industries, as well as in pharmacology. In 2007, the Mud Volcanoes State Nature Reserve was created on the Absheron Peninsula. In June 2024, the Mud Volcanoes Tourism Complex opened within the Gobustan State Historical and Cultural Reserve. ==Volcanoes==

The Gotur Dag volcano, located 70 km from Baku, is tall with a depth of . Its last eruptions occurred in 1966 and in 1970. The overall volume of breccia is about . Bahar volcano is located 55 km from Baku, with a height of . The last eruption was detected in 1993. Lokbatan volcano is located from Baku. Several eruptions were recorded in the 19th century, and the most recent took place in 2001. The Ayranteken volcano is one of the most active volcanoes in Azerbaijan. Located 65 km from Baku, many eruptions are accompanied by underground explosions and huge flames. The volcano reaches 190 meters. Its first eruptions are dated 1964 up to 1990. The last eruption of the Moose volcano occurred in 1970, when flames rose to heights of up to 1 km and local seismic activity was recorded. On July 4, 2021, at 21:51 local time, an 8-minute long mud volcano eruption on Dashli ada in the Caspian Sea, located 10 km from an oil platform off the coast of Azerbaijan, caused a massive explosion and fireball. The flames reached heights of 500 meters and were visible across the region, including from Baku 74 km to the north. There were no reports of injuries or damage to any oil platforms. It was speculated to either have been the eruption of a mud volcano, or the explosion of a gas pipeline. However, scientists confirmed that the explosion came from a mud volcano called 'Makarov Bank', and occurred near the Umid gas field, where there are both gas pipelines and natural pockets of compressed gas, as are commonly found in the Caspian Sea. The most recent previous volcanic eruption on the island was recorded in 1945, and the one preceding it in 1920. ==References==
