Abstract
Induced seismicity on the north of Ukrainian right bank, Zhytomyr region, resulted from the large number of quarry openings and direct blasting operations conducted on them. The study of natural seismicity gets more complicated due to these activities. Moreover, with a relatively low level of local earthquakes there are many seismic events with the same intensity, which are generated by different types of explosions.
The analysis of seismic records, collected from the large number of blasting operations in the massive quarries, has shown that a maximum of spectrum amplitudes in a spectra of explosion records are observed on the frequencies less than 1 Hz.
According to the results of processing, the observable blasts in Zhytomyr region and adjacent areas can be classified as 4–6 energy classes.
