Sousaki volcano 2013
Photos of an excursion to the volcanic site of Sousaki with its strange geology. Even all rocks are alterated by volcanic fluids and gases, it is strange, that one can not really find typical volcanic rocks, like dacites or andesites. There are two caves with dangerous activity of gases like H2S, CO, CO2.
