volcano A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most oft ...

, at the northwest end of the South Aegean Volcanic Arc. The volcano was active during the Pliocene and early Quaternary Period (geology), periods of the Earth's geological history. There is still significant solfataric activity at this location. The volcano erupted dacite lava.D’Alessandro, W. (2006

a chapter in ''Geo-Environment & Landscape Evolution II'' edited by Martin-Duque J.F., Brebbia C.A., Emmanouloudis D.E and Mander U., Southampton, WIT Press, pages 369-378. The geothermal system releases about 1 Tonne, megagram per day of gases at 42 °C, 90% carbon dioxide, CO₂ and < 1% each of methane, CH₄ and hydrogen sulfide, H₂S. The earthquakes of 1997 of 3-4 R had as a result the uprising magma in higher areas of the earth crust. So future activities are possible. 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.
