Carpathian complex prognostic poligon has being created for testing of new methods and equipment and their implementation into the practice of seismotectonic investigations in the Transcarpathians. The polygon consists of a network of regime geophysical stations (RGS). I analyzed seismicity of the Ukrainian sector of the Carpathians. It is determined by local earthquakes and strong subcrustal earthquakes of the Vrancea zone in Romania. In this paper, I estimate the most fundamental parameters describing earthquakes: seismic energy E and energy class K=log(E) in a time window of 40 years (1961-2001). Our results show that, the E1 / 2 plot against time may be a good tool for understanding of a local earthquake activity, although the shape of the plot is strongly influenced by extreme events. Also, we have found a correlation between seismic moment M0 and energy class K of the local earthquakes for Transcarpathian region.
Key words: seismicity, energy class, seismic energy, seismic moment, geodynamic polygon, catalogue.
