GPS - Saronikos

The NW Hellenic volcanic arc consists of the Plio-Pleistocene volcanic centers of Susaki, Aegina, Methana Penisnsula and Poros. It lies in the neotectonic basin of Saronikos Gulf, divided in a western active part and an eastern relatively inactive part, through a shallow platform, which implies the existence of a NE-SW-trending rupture zone.

The kinematic pattern of the NW volcanic arc was studied by DGPS measurements, for the period 2006-2008 (Papageorgiou PhD Thesis). The GPS network was established and firstly measured in 2006, while two more measurements were carried out, in 2007 and 2008. The network was comprised of five (5) stations, the two of them placed at Methana (MET1 & 2) and each one of the rest in Aegina (AEGI), Susaki (SUSA) and Athens (UOA1). During the measurements an extra site (OBSV) was occupied, located in Geodynamic Institute of NOA. The results reveal significant deformation features underlying the partition of the two basins of Saronikos Gulf.
