Summary The eastern Mediterranean is a region of complex tectonic processes and associated horizontal and vertical displacements. A high precision gravity network has been established in the Atalanti area of central Greece to monitor temporal gravity changes on an annual or more frequent basis. A total of 68 sites have been measured in 1981 and 1982 with a maximum single instrument standard deviation of 0.08 gravity units after a least squares network adjustment. Analysis of the gravity differences between the two measuring epochs exhibits no change of gravity over the network with a precision of 0.11 gravity units. It is proposed that the gravity values given form a stable base for continued observations which will enable the authors to resurvey the region in the event of precursory foreshocks. Observation of the Atlantic network will continue on an annual basis preserving the same observation sequence for reasons of symmetry.
