Extensometric method on study of seismotectonic processes in source areas of Transcarpathians earthquakes

In the paper the history of development and methodical-apparatus supply and results of extensometric observations in the Beregovo hills area in Transcarpathians in particular in Mujievska (Grand Beregivska) mountain is shortly described. The method of separation and results of analysis of deformation anomaly – precursor of perceptible 1989 Vynogradovo earthquake is given. The changes of geomechanical regime of Mujievska mountain rocks massifs till and during and after this earthquake are traced.
