The build-up of the Methana stratovolcano at the NW corner of the Hellenic arc involved a variety of hazardous phenomena including explosions, pyroclastic flows, and lava flows. Since 230 BC (age of last eruption) the volcano entered a period of volcanic quiescence. We can gain insights into volcanic hazards in Methana by tracking subsurface processes such as magma and hydrothermal fluid migration using volcano seismology, geochemistry and GNSS studies. Moreover,recent advances in analysis and interpretation of seismic and GNSS data from permanent and non-permanent networks on Methana may facilitate a precise characterization and quantification of the physical processes leading to and producing volcanic phenomena. We welcome submissions that explore new seismic, geodetic and geochemical observations, interpretations, models,instrumentation, or techniques that promote our understanding of volcanic processes and assist in future monitoring efforts at Methana.
