Commencement 1976 • Realization in three phases: • Phase I (1980 – 1985): • Investigations: (Geotechnical, Geophysical, Hydrotechnical) • Installation of the entire array • Phase II (1986 – 1988): • Testing (excitations, field forced vibration, frequency range 2 – 40 cpc) • Phase III (1989 – …….): • Exploatation of the network • Several earthquakes (M = 5.0 – 5.5; Albania, Greece, Macedonia)
