Processes of faulting in the sources of perceptible earthquakes in the Precarpathians and Transcarpathians

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.
