BackgroundAegina is part of the Saronic Gulf Volcanic Group, in the Hellenic Volcanic Arc. The complex consists of domes and lava flows erupted from effusive monogenetic centers with low eruption rates (0.4 km3/m.y. at Aegina) (D'Alessandro et al., 2008). Activity took place between 4.7 and 2.0 Ma, during the first part of which mostly basaltic-andesitic to rhyodacitic rocks were produced. The remaining 1 m.y. of its activity produced basaltic-andesitic rocks (D'Alessandro et al., 2008; Francalanci et al., 2007). Volcanic activity had ceased in the upper Pleistocene, but a low-temperature geothermal field presently exists (Keller, 1971; Francalanci et al., 2007).
