A mud volcano erupted in Taiwan on Wednesday spewing water with sediments and gas.
Video shows locals enjoying the spectacle by throwing flaming rags into the volcano, which sets alight the methane gas emitted during the eruption.
The Wandan mud volcano is a particularly unusual example of the geological phenomenon, an expert has told the BBC.
Geologist Dr Mark Tingay said that although this mud volcano primarily erupts in the same spot in southern Taiwan, new eruption sites have been known to pop up kilometres away.
The mud volcano has erupted 11 times in three years.
