Sousaki cave (Western Greece and the Ionian)

Volcano: Crommyonia (Sousaki) (see Crommyonia (Sousaki) at the Smithsonian Institution website in a new tab)
Type: Cold Vent
Description: About 5 km west of the village of Agioi Theodori there is an anomalous degassing area called Thiochoma. The area is also known for the low enthalpy hydrothermal system of Sousaki. The area is characterized by widespread alteration and stunted or absent vegetation. Some artificial caves have been dogged in the area to extract sulfur and sulfates in the past. Some of these caves are now gas emission points from their bottoms. The strong gas flux creates gas accumulation on the bottom that finally flows out from the cave entrance. Gas samples were mostly collected from two caves about 10 m apart from each other. The caves called “big” and “small” have the following dimensions (height × width × depth) 8 × 3 × 10 m and 4 × 1.5 × 4 m respectively.
