IN GENERAL

The Seismological Observatory at the Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius University, Skopje, Republic of Macedonia, according to the Law of Participation  the Republic in the Financing of the Seismological and Engineering-seismological Activities (Official Gazette of the SRM, No. 18, 10 October 1983, pp. 330 331), is the only institution in Republic of Macedonia that is authorized and obliged to maintain the seismological network in the Republic, to perform permanently the seismological monitoring of the seismic activity in the territory of the Republicand wider, to make the corresponding scientific research (including the defining of the seismic hazard), to compile and update the map of seismic zonation of the territory of the Republic of Macedonia, to store the seismological data, to public the seismological data (including the reports to the public about the felt earthquakes in the Republic), as well asto participate in the international exchange of seismological data. This institution is also responsible for the educational activities in the fields of seismology and geophysics. It also has publication rights.

The Seismological Observatory at the Faculty of Natural Sciences and Mathematics in Skopje is the first seismological institution in the Republic of Macedonia. It was founded by the Government and Parliament of the Republic in 1957, with the title Seismological Station of the University in Skopje. This station was the only seismological institution in the Republic that was in operation during the 26 July 1963 Skopje strong earthquake. After this earthquake, the station was a host of many world-known seismologists and seismological institutions. It also participated in many national and international scientific projects, as well as in many applications during the construction of important buildings in the Republic. Following the world trends in seismological instrumentation and scientific methods, the station founded two new seismological stations in the territory of the Republic in the 1960-ties (in Valandovo and Ohrid). With such activities, the station changed its status into Seismological Observatory of the University “Ss. Cyril and Methodius” in Skopje, 1966. In 1976, this observatory became a section of the Faculty of Physics in Skopje of the same university, while in 1984 it became an institute within the Faculty of Natural Sciences and Mathematics of the same university this observatory became a part of the Faculty of Natural Sciences and Mathematics of the same university.

Presently, the observatory maintains six permanent seismological stations (Skopje/SKO, Štip/STIP, Valandovo/VAY, Ohrid/OHR, Bitola/BIA and Kruševo/KRUS), equipped with wide-range or short-period seismometers and digital recorders. modern  a telemetric seismological network. These stations are connected in a telemetric network via INTERNET. Again via INTERNET, this network is included in a real-time data exchange with many seismological stations from the Balkans. The data acquisition and analysis centre is in the station in Skopje, which is the seat of the observatory. The observatory maintains in the moment five temporary stations, four of which monitor the induced seismicity by the water accumulations at dams of new-build power stations. 

After the above mentioned law from 1983, the Institute of Earthquake Engineering and Engineering Seismology (IZIIS) at the "Ss. Cyril and Methodius" University in Skopje, founded by the Government and Parliament of the Republic in 1965, is the institution which is authorized and obliged to maintain only the strong-motion seismological network in the Republic of Macedonia, to store, analyze and public the obtained data, to create data-bases for defining the seismic risk, to prepare the technical normative for design and construction of aseismic buildings in accordance with the map of seismic zonation of the territory of the Republic, to give a professional help in the classification of the damages and the evaluation of the usability of the buildings after the strongest earthquakes, to prepare the common and technical normative for demolition, cleanup and repair of damaged buildings in the strongest earthquakes, as well asto participate in the international exchange of the strong-motion seismological data.
