| Epicenter of explosion (fig. 2) has been calculated with data from 11 stations. Waveforms from 5 stations (Vladivostok, Hailar, Seymchan, College Outpost, Tennant Creek) were obtained at GS RAS in a near to real time mode, information from other stations was obtained in the form of detected arrival list from international center CTBTO_IDC. |
