The Tsouka volcano
The volcano Tsouka dominates the west side of the Methana peninsula and adjoins the volcano Chelona, which is probably younger? Maybe it is also the outer edge of the former caldera? It pulls down to Megalochori and is quite steep due to erosion. It is probably a fissure eruption and, as most volcanoes in Methana, know from the dacite rock that forms the lava domes.
