A fire tornado rises from burning peat on a farm in Bangor, U.K., in 2008.
Combustible, carbon-rich gases released by burning vegetation on the ground are fuel for most fire tornadoes, Forthofer said. "The vegetation on the ground heats up enough to release gas, but some of the gas can't combust, because it doesn't have enough oxygen around it."

On June 30, 1908 at approximately 7:15AM, a huge explosion occurred in a remote, mosquito infested swamp near the Tunguska River. A local reindeer herding tribe, called the Evenki, described seeing a bright, white light streak across the sky.
