Sousaki volcano
Thiochoma canyon, Sousaki
Sousaki (Greek: Σουσάκι) is an extinct volcano and modern solfatara field in northeastern Corinthia, Greece, at the northwest end of the Aegean volcanic arc.
The volcano was active in the Quaternary period between 4.0–2.3 million years ago and today has significant solfataric activity. The geothermal system releases about 1 megagram per day of gases at 42 °C, 90% CO2 and < 1% each of CH4 and H2S.
The last eruption of this volcano was a side eruption which created new land in the Gulf of Megara, where there are major port and refinery facilities.
