Methana Volcano | John Seach



36.40 N, 22.33 E
summit elevation 760 m
lava domes

Methana volcano consists of a lava dome complex which forms the Methana Peninsula. It is joined to the mainland by a 300 m wide isthmus.

Methana volcano belongs to the volcanic group of the Saronic Gulf, which consists of the volcanic centres of Sousaki, Aegina and Poros.

Geothermal activity at Methana consists of hot springs of Loutra Methana and Agios Nikolaos, and recent fumarolic activity at the Thiafi Bay area.

Loutra Methana
Loutra Methana is located at the southern end of the town of Methana, comprises a group of springs issuing from fractures of the Asprovouni limestones close to the coast. They are hydrogen sulphide springs and are used as a thermal bath by a nearby hotel. The estimated total water flow of the spring is several tens of litres per second.

Pausanias spring (Palea Loutra)
The spring of Pausanias is located near the settlement of Agios Nikolaos on the NE part of the peninsula, close to the coast. The thermal waters appeared soon after the volcanic eruption around 230 BC. The spring has been used by local
inhabitants since Roman times.

Kameno dome is the site of the most recent eruption in 3rd century BC when lava flowed to the sea.
