In the paper discusses the features of long-term seismicity (1961-2010) the territory of Transcarpathian depression and separate seismoactive zones (A, B and C). The relationship of these zones with the main tectonic elements of depression is set. It is proved that the boundary between zones A and B passes through Oash deep fault.
Purpose. Getting new knowledge about the processes in the centers and focal areas of perceptible earthquakes in the Pre-Carpathians And Trans-Carpathians . Methodology. To study the processes of faulting we used a technique which is based on the notion of the source as a moving, extended source.The parameters of azimuth hodograph τ (Az) - travel time of focal waves Pi –are used to determine the length of the rupture, the rate of its ripping, the propagation direction of the rupture in the focal zone of the earthquake.
Earthquake of Olesky area and surrounding areas within the Lviv region and in particular some features of earthquakes in V. Mosty (1875) and Komarno (2007) as well as influence on a given territory from Vrancea zone earthquakes (in particular, the earthquake in 1838) are analyzed. According to foreign reports about the influence of the method of hydraulic fracturing on seismicity the conclusion about possible changes of seismic regime of the area and increase the possible danger to water resources of Lviv region from shale gas extraction were made.
