Exploitation of the IMS and Other Data for a Comprehensive Advanced Analysis of the North Korean Nuclear Tests
Abstract
On May 25, 2009, the North Korea conducted a second underground nuclear test at a location very close to that of their initial 2006 test in a remote, mountainous region of northeastern North Korea. The objective of this study was to exploit International Monitoring System (IMS) and other open data sources to conduct comprehensive, advanced analyses of the characteristics of these two North Korean nuclear tests. These studies focused on refining event location, estimating source depths and seismic yields and evaluating the effectiveness of the various seismic event identification criteria as applied to these two explosions. Seismic data recorded at stations of the global IMS network were augmented with seismic data from key regional (<20 degrees) obtained from the Incorporated Research Institutions for Seismology (IRIS) data management center, the Ocean Hemisphere Project Data Management Center (OPHDMC) and the Japanese National Research Institute for Earth Science and Disaster Prevention (NIED).
