Abstract


Results of analysis of the wave pattern and spectrograms of seismic events in the Dnieper-Donets aulakogen registered by a group of stations of the Main center for special control of MSAU have been presented. The sources of the earthquakes with magnitude mb = 3.0; 4.5 are situated at a depth of 3-10km at the boundary of graben zones: the central zone and the southern one adjacent to the edge near Poltava city and also on the northern fault near Lebedyn city of Sumy district. Relationship  of local seismicity and special features of  the earth crust structure in these areas of aulakogen revealed according to geological-geophysical data has been considered.
