The results of the implementation of one of the effective variants of the methodology for specifying the hypocenter of earthquakes in the Boryslav – Stebnyk area (Ukrainian Precarpathians) are presented. The relevance of the study is associated with the complex, significantly inhomogeneous depth-spatial velocity structure of the earth's crust in the subregion. Traditional approaches to the hypocentering of earthquakes using horizontally layered crust models and corresponding hodographs give significant (up to several km in coordinates and depth) errors in the localization of the foci of local seismic events. To eliminate them, we, among others, proposed and implemented an approach that takes into account the real velocity structure of the earth's crust in the subregion according to regional profiles data. The corresponding methodology was implemented using modern computer and GIS technologies, as well as specially developed software. The results of its application are illustrated by the example of the karst-collapse technogenic earthquake of 2017 near Stebnyk, for which the factual localization of the focus is precisely known.
