Azerbaijan is home to more mud volcanos than any other country in the world. These volcanos are formed when mud, gas, and water are expelled from great depths in the earth's crust.

This particular mud volcano is not as active or as large as many volcanos in the Gobustan region. High winds made it very difficult to hold the camera steady without a tripod. The town you can see in the distance is Sahil, Azerbaijan.
