Identification of quarry blasts in the Carpathian region of Ukraine by the criterion of similarity of their waveforms

The criterion of similarity of waveforms at the same station is suggested for identification of quarry blasts conducted on regular basis at local extraction cites of Carpathian region of Ukraine. Case study is presented of the identification of quarry blasts from epicentral area of Dovhe-Irshava, conducted there during 2005–2007. The conclusion has been drawn that the criterion is effective and applicable for removing the quarry blasts from catalogues of local earthquakes.
