One of the most famous Mud volcanos in Sistan and Baluchestan province is known as Gel-Afshan-e Bandar-e Tang, which is located 110 km away from Chabahar. The general impression is that this is the only Gel-Afshan around Chabahar, while there are other nearby, which of course are different in appearance.
Gel-Afshan-e Chegardani-Lash is located near a village of the same name, which is necessary to visit with the help of local people due to the lack of traffic signs. This mud volcano, like the Bandar-e Tang, creates a low-lying hill with its continuous activity and the flower comes out of different parts of this hill in a variable manner.
The activity of this mud volcano is usually more than that, and the interval between each time the flower leaves the mouth is less than one minute.
Mud volcanos are usually caused by pressure from hydrocarbon gases in the ground. In this way, the gas along its path to get out of the ground also brings with it some water and mud from the depths of the earth. These gases are flammable and this could be a proof of this hypothesis.
