ABSTRACT

This work focuses on the assessment of seismic risk issues associated with the
potassium salt deposit of Provadia and Soligorsk. The long-term studies 1983-2007 of
the only terrestrial Bulgarian salt deposit (Provadia - 43.060N, 27.450E) and Belarusian
(Starobin - 52.840N, 27.470E) in connection with the observed higher seismic activity
and probable manifestations of technogenic seismicity in the region is presented. The
characteristic features of the seismic processes as the identity of the curves of
recurrence of seismic events of the energy range of 4÷8; a quasi-periodic character of
the seismicity activation in time against the general trend of seismicity activation
increasing are established. It is shown that zones of epicenters of seismic events are
larger that mining areas. Some differences in the pattern of seismic processes, such as:
seismic activity in the range of small energies (K=4÷8) is higher in the Soligorsk
region; events of the higher energy class K>9 characteristic of the Provadia region are
carried out.
