Possible consequenses of the technogenic seismic impact on geological environment of the central part of East European craton from the small-aperture seismic group «Mikhnevo»

Abstract

The results of natural and man- made seismicity long-term observations on the Eastern European Platform (EEP) according to the data of the small-aperture seismic group (MSG) “Mikhnevo” IDG RAS are summarized. It is shown that technogenic seismicity is dominant in this area. Descriptions of wave forms from blasts at the largest quarries of the Belgorod and Kursk regions are given. Special attention to the assessment of energy from explosions produced at numerous relatively small quarries located in the central part of the EEP is paid. The energy assessment of the total technogenic impact on the environment is given. The results of registration and location of natural-tectonic events that occurred on the territory of the central part of the EEP, previously considered aseismic, are shown. The negative impact on the territories located near the existing quarries from the resulting dust and gas emissions during drilling and blasting and other mining operations was noted.
