Seismic events found by waveform cross correlation after the announced underground nuclear tests conducted by the DPRK on 12.02.2013 and 06.01.2016. Aftershocks or hidden nuclear tests?
Ivan Kitov, Dmitry Bobrov, Mikhail Rozhkov
The multi-master method based on waveform cross-correlation has found several aftershocks of the third (DPRK3) and the fourth (DPRK4) announced underground nuclear tests conducted…
Comprehensive recovery of a weak aftershock sequence in the North Atlantic using waveform cross correlation
Dmitry Bobrov, Ivan Kitov, Mikhail Rozhkov +1
We apply cross correlation between multichannel seismic waveforms as a technique for signal detection and automatic event building at the International Data Centre (IDC). This tech…
Waveform cross correlation applied to earthquakes in the Atlantic Ocean
Dmitry Bobrov, Ivan Kitov, Mikhail Rozhkov
We assess the level of cross correlation between P-waves generated by earthquakes in the Atlantic Ocean and measured by 22 array stations of the International Monitoring System (IM…
Waveform cross correlation for seismic monitoring of underground nuclear explosions. Part II: Synthetic master events
Dmitry Bobrov, Ivan Kitov, Mikhail Rozhkov
Waveform cross correlation is an efficient tool for detection and characterization of seismic signals. The efficiency critically depends on the availability of master events. For t…
Waveform cross correlation for seismic monitoring of underground nuclear explosions. Part I: Grand master events
Dmitry Bobrov, Ivan Kitov, Mikhail Rozhkov
Seismic monitoring of the Comprehensive Nuclear-Test-Ban Treaty using waveform cross correlation requires a uniform coverage of the globe with master events well recorded at array…
International Data Centre: Reviewed Event Bulletin vs. Waveform Cross Correlation Bulletin
Dmitry Bobrov, John Coyne, Jeffrey Given +5
Our objective is to assess the performance of waveform cross-correlation technique, as applied to automatic and interactive processing of the aftershock sequence of the 2012 Sumate…
Perspectives of cross correlation in seismic monitoring at the International Data Centre
Dmitry Bobrov, Ivan Kitov, Lassina Zerbo
We demonstrate that several techniques based on cross correlation are able to significantly reduce the detection threshold of seismic sources worldwide and to improve the reliabili…
