It is known as ‘The Volcano of Monte Busca’, and the smallest in Italy – barely more than a small pile of rocks on a hill.
It has been attracting tourists for decades, with thousands making the climb up the slope near Tredozio village, Province of Forli, every year.
However, while it falls under the definition of ‘volcano’, the four-foot-high burning mound has no crater and expels none of the lava commonly associated with the term.
The volcano of Monte Busca is a natural gas vent.
Hydrogen gases from underneath the surface burn when they come in contact with oxygen, causing the flame on the mountain to burn day and night.
The natural phenomenon is also known as ‘flaming fountain’.
