Mud volcano Goturdagh

Mud volcano is situated 70 km south-west off Baku and 3km off mud volcano Ayrantokan. Its relative height is 150m. In terms of morphology is looks like truncated cone with sunken caldera 150m in diameter and 15-20m depth. Mud volcano Gorurdagh is very interesting and a solitary by its activity nature in Azerbaijan distinguished from other mud volcanoes by particular features of its activity. A quite intriguing eruption phenomenon has been observed during over 100 years within volcano crater where dome-shaped mud breccias are being squeezed out of 50m long and 15 m wide crescent shape fracture. Just like paste   

is squeezing from a tube half liquid paste is beingsqueezed upward then it breaks and creeps down the slop. First this phenomenon was found out in 1926 when squeezing rate of mud breccias was calculated to be 42mm/yr. This phenomenon continued until 1966 after which a regular eruption occurred in October, 1966 and later on in spring, 1970. Simultaneously, 25m long and 10 high ellipsoidal shape mud breccias squeezing phenomenon has been continued. Mud breccias squeezing rate was 2.5 m a month. There is some mud volcano lobes extended northwards more than 1 km long. Area covered by mud breccias measures about 408 he, whereas total volumetric amount of outburst mud breccias is over 530M cu m with average 130m.
