BackgroundMethana volcanic system comprises a group of 32 lava mostly dacitic lava domes, whose formation started about 1-2 million years ago. The latest activity was likely around 1700 AD in form of a submarine eruption off the northern coast.
An active hydrothermal system characterizes the area, controlled by a E-W fault system that crosses the town of Methana where thermal springs are found.
