Abstract. Using the developed geoinformation system “Prediction”, an analysis was made of information available from the media on two devastating earthquakes in the Türkiye that occurred in the western segment of the East Anatolian fault on February 6, 2023. The possibilities of recognizing signs of the preparation of earthquake data by means of medium-term forecasting developed for the Baikal rift zone, which are important for assessing seismic hazard and seismic risk, are discussed. Based on the analysis of the consequences of the large-scale destruction of residential and industrial infrastructure in the Türkiye, the causes of the huge damage to the country's economy caused by earthquakes, which are largely due to unfavorable seismotectonic conditions and urbanization problems that arose as a result of insufficient compliance with the necessary requirements and norms of earthquake-resistant construction, are considered.
Keywords active faults, seismic regime, medium-term forecast, seismic hazard, seismic risk.
