Geology of the Methana Peninsula, Greece: volcanism in the Peloponnese.
Methana is located on the east coast of the Peloponnese, in the southern part of Greece. The Methana Peninsula projects northward into the Saronic Gulf, connected to the Peloponnese by a narrow gooseneck. The Peloponnese is also a peninsula, separated from the central part of Greece by the Isthmus of Corinth. The Peloponnese has a rugged, mountainous interior and deeply indented coast. Methana has a similar topography, but the geology reveals an active or dormant volcanic complex, rather than Mesozoic metasediments. Geothermal activity includes hot springs and gas exhalations.
