dc.description.abstract | The Democratic People’s Republic of Korea (DPRK aka North Korea) conducted underground nuclear explosions on October 9, 2006 (M 4.3), May 25, 2009 (M 4.7) and February 12, 2013 (M 5.1). We expanded standard depth calculation methods to encompass full depth utilizing spectral s of spectra using body waves and Rayleigh waves from local and teleseismic arrays. The depths of burial were calculated from the fundamental-mode Rayleigh wave spectra as well as the average spectra of depth phase (pP + P/sP + P, pPn + Pn/sPn + Pn) considering take-off angles based on the flat Earth model. The average depths of the 2006, 2009 and 2013 nuclear tests were thus estimated at 2.12 km, 2.06 km and 2.05 km, respectively. It should be noted that those depths are significantly greater than expected from the standard experiment practice. The possibility of the over- buried nuclear tests would affect the interpretation of MS-mb discriminants as well as the estimation of the yield. | en_US |
dc.description.sponsorship | We wish to thank Robert Herrmann for reviewing this manuscript and offering very constructive criticism. We would like to thank Paul Richards for his providing Dongbei Seismic Network (dsn) data and Rick Benson (IRIS) and David Jepson (Geoscience Australia) for the teleseismic data and Korea Meteorological Administration (KMA) for providing local waveform data. We also appreciate Albert Brouwer as well as the Executive Secretary of CTBTO, Lassina Zerbo and Director of International Data Centre (IDC), W. Randy Bell for their collaboration in IDC data collection for this study. One of author (SGK) would greatly appreciate CTBTO's funding to participate in SnT2015 and SnT2017. We are also grateful to Director of ISC (International Seismological Centre), Dmitry Storchak for providing phase reading data for this study. | en_US |
