- Аннотация: It is necessary to have reliable data on thedistributions of earthquake hypocenters in the study area to solve many geological and geophysical problems,in particular, the forecast of strong earthquakes, seismic zoning, and earthquake-proof construction.In turn, the completeness of the data onthe distribution of earthquake hypocenters and the accuracy of their determination largely depends on the effectiveness of the observing system. The efficiency of the modern Carpathian network of seismologicalobservations consisting of 196 stations isestimated in this article. By the effectiveness of the seismological observation network we mean the ability of the network to record events with minimal magnitudes at certain epicentral distances and allowing us to determine its main parameters (origintime and coordinates of hypocenters) with minimal errors depending on the position of the hypocenter of the earthquake. The calculation of the minimum earthquake magnitudes for the Carpathian seismologicalnetwork shows that if each station has amagnification of 40,000, then the seismological network reliably records earthquakes with a magnitude of 3 or more in the Carpathians. The errors in thedetermination of the coordinates of epicenters of earthquakes in latitude (δφ) (km) and in longitude (δλ) (km) do not exceed 0.4 km in the center of the network and 1.0 km on the periphery of the network. The values of errors for determining the depths of the earthquake (H) (km) in the center of the network does not exceed 1.0 km and does not exceed 10 kmthroughout the Carpathian region.
