Mud Volcanoes. Azerbaijan
Azerbaijan boasts the largest number of mud volcanoes in the world with roughly 800. Although they look tame and inviting to those keen on mud baths, they can cause quite a bit of damage. Mud volcanoes have been known to erupt with great force sending flames shooting into the sky as high as 1000 meters and tons of mud dispersed over the ground. In one eruption, the flames could easily be seen from 15 kilometers away, and would still be burning three days later. Of course, it would be very disastrous to be enjoying a mud bath on the day of an eruption.
