Identification of Quarry Blasts Aided by Infrasound Data

Abstract We present our analysis of the detections from Piszkés-tető, Hungary infrasound array that has been operational since May 2017. introduce an automatic search method to associate with a preliminary list explosions detected by seismic network. Once are associated events, we relocate events using both arrival time and azimuth observations. validate methodology on ground truth i.e., confirmed mine operators. demonstrate seismo-acoustic locations able identify source even for closely spaced quarries. The discriminative power is strongest at near-field distances, where local regional discrimination methods have most difficulties.
