چکیده:

Based on retrospective analysis of multidisciplinary observations in research seismoactive zone for current seismic hazard assessment [1-3], practically all seismic events which had occurred from 1983 till 2002 in the territory of Armenia and adjacent territories are systematically tested. The precursory anomalies of 11 strong regional (.=6.0) and 7 perceptible local earthquakes (.=3.7) are classified. The tests were made within several years, with inclusion of new seismic events occurred and in process of new data acquisition from observation stations. The Catalogue of precursors was supplemented few times, and the anomalies included were critically overestimated and sometimes rejected. Naturally, the Catalogue will be supplemented with the tests of future strong regional and perceptible local earthquakes. At the end of the Catalogue, the summary table is given, where the data on parameters of the tested earthquakes and precursory anomalies are provided. The Catalogue is in daily use at the Unified Center for Seismic Hazard Assessment of Armenian NSSP for current seismic hazard assessment.
