Integral Nature Reserve of Macalube di Aragona is a regional nature reserve in Sicily, located 4 km southwest of Aragona and 15 km north of Agrigento, which includes a wide argillaceous area characterized by the presence of phenomena eruptive.
Volcanoes are the result of a rare geological phenomenon called sedimentary volcanism.
The phenomenon is related to the presence of substantial small clay soils interspersed with brackish water layers dominant methane gas bubbles subjected to a certain pressure. Gas, through the discontinuities of the soil rises to the surface, carrying with him the clay sediments and water, resulting in a mud cone whose summit is like a volcanic crater. The phenomenon is sometimes with explosive character, with ejection of clayey material mixed with gas and water, projected to a considerable height. In recent years, an intense and sudden explosive activity is marked by the issuance of large volumes of sludge. Researchers have shown a correlation between explosive activity and seismic activity at the local level, requiring further interdisciplinary studies
