Abstract
The modern seismic activation of the main oil and gas areas of the Pre-Carpathian foredeep – Dolyna (1974–1976), Nadvirna (1996–2013) and Boryslav (2014–2017) was traced. The refinement of the location of the studied earthquakes courses is carried out on the regional travel time tables and the method of residuals minimizing. The directions of ruptures breaking in the foci of the stronger ones were studied, the ruptures lengths and other parameters of these courses were estimated. The spatial models of seismic activity of the main seismogenic structures in these areas have been constructed. It has been established that most of the earthquakes courses tend to transverse faults of the anti-Carpathian (northeastern) direction (in the zones of their intersection with the Precarpathian deep fault), which cross or limit the oil and gas structures, part of the courses tend to the ones available here thrusts and folds of different depth. Taking into account the long-lasting (starting from the 19th century) active production of oil and gas condensate here the local seismicity, obviously, is additionally technogenically provoked (induced).
