When Mount Sinabung erupted in North Sumatra, Indonesia on Saturday, the pyroclastic flows making their way down the mountain left red-hot deposits along its sides.
Incredibly, as the air above the deposits heated and quickly rose, a group of small "tornadoes" were formed, twisting their way down the mountainside as well.
The video of the event, captured by Dr. Richard Roscoe of Photovolcanica, is astoundingly surreal. Check it out above for yourself.
