Introduction
The establishment of the Laboratory of Geophysics in 1977 was followed by the installation of a telemetry seismological network in the area of northern Greece which officially started operating on 1 January 1981. The seismological network obtained its present configuration in three phases.
During the first phase (1980 - 1989) the network consisted of the central seismological station of Thessaloniki (THE) and seven peripheral stations in Sochos (SOH), Litohoro (LIT), Griva (GRG), Paliouri (PAIG), Kentriko (KNT), Ouranoupolis (OUR) and Serres (SRS). The selection of these sites was done on the basis of both scientific and social purposes. The network of these eight stations adequately covered the part of the Serbomacedonian zone which belongs to the Hellenic territory. The seismicity of this zone is the highest in the area of northern Greece. This network was the first telemetry network in the area of Greece and the first one supported by computer system in the whole Balkan area.
The network was expanded in 1989 (second phase) with the installation of four new seismological stations at Igoumenitsa (IGT), Florina (FNA), Alexandroupolis (ALN) and Agios Georgios (AGG).
All these stations are equipped with three (Z, N-S, E-W) short period seismometers (S-13 Teledyne-Geotech). Additionally, in the central station of Thessaloniki 3-component long-period seismometers (SL-210 Teledyne-Geotech) are in operation since 1981. The seismic signals from these seismologic stations are transferred directly to the central seismological station of Thessaloniki by leased telephone lines. This network was the first telemetry network in the area of Greece and the first one supported by computer system in the whole Balkan area.
During the period 1996-1999 (third phase) four more stations were installed in Lemnos island (LOS), Alonissos island (AOS), Xorichti (XOR) in Pelion Mountain and Lefkada island (LKD), improving the azimuthal coverage of North Aegean area and Ionian islands, which is of particularly high scientific interest and increasing the detectability of the network. In these stations vertical short-period seismometers (S-13 Teledyne-Geotech) are installed, while the transmission of the seismic signals to the central seismological station is wireless in UHF frequency band.
