Seismicity of the Carpathian region

Abstract

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.
