The Patras Gulf located in the Western part of Greece is an area of very high seismic activity; a event in the region was the Egion (M=6.2) earthquake of June 1995 and the Andravida Earthquake (Mw=6.4) in 2008.

A GPS network of ten (10) stations was established in 1994 and remeasured up to 2011. Significant micromovements were detected, confirming the anticipated tectonc movements of the area.
