The Otman-Bozdag mud volcano is one of the largest and most active mud volcanoes in Azerbaijan. It is located approximately 40 km from Baku, near the village of Umid in the Garadagh district. The volcano is 400 meters high, and its summit contains a volcanic crater 300 meters in diameter. Salts and gryphons are active here, periodically erupting a mixture of liquid mud, oil, and gas. As a result of numerous eruptions, powerful mud flows of varying ages have formed on the slopes, reaching several kilometers in length. Otman-Bozdag is part of the "Mud Volcanoes of Baku and the Absheron Peninsula" State Nature Reserve.

As is known, on the morning of October 11, between 8:30 and 9:10 AM, another eruption of the Otman-Bozdag mud volcano occurred.

Staff from the A. Aliyev Institute of Geography of the AR MSE—PhD in geography, doc. Saida Zeynalova, PhD in geography, doc. Elina Kerimova, and PhD in geography, doc. Museib Yunusov—conducted observations in the area of the mud volcano's eruption.

Based on preliminary observations, it was concluded that the October 11 eruption saw a strong gas release, resulting in a flame column rising to a considerable height. However, the ejected breccia material was insufficient to form breccia flows down the volcano's slopes, and the mud mass was distributed only within the crater. Unfortunately, difficult conditions prevented access to the volcano's crater and the necessary research.

The volcano's most recent eruption was recorded in 2018. During that eruption, a large amount of breccia material was ejected, spreading for several kilometers along the volcano's southeastern slope, all the way to the highway.

According to a brief survey conducted by researchers among local residents, a loud rumbling sound was heard during the 2018 eruption. However, no such sound was observed during this eruption.
