In late September and early October 2017, the International Monitoring System and several national radiation surveillance networks in Eastern and Western Europe reported low levels of the airborne radionuclide contaminants ruthenium-106 and ruthenium-103, with both species being CTBT relevant. Filters from the national networks of Sweden operated by the Swedish Defence Research Agency,...
The resonance seismometry is one of the CTBT’s permitted techniques during OSI. Numerical modeling of seismic wave fields makes it possible to investigate resonance phenomena and their signatures in free-surface records. The necessary condition for reasonable results is an optionally accurate and computationally efficient numerical-modeling tool together with a sufficient set of realistic...
We estimate seismic full moment tensors and their uncertainties for seven events at the North Korea nuclear test site, consisting of six declared nuclear tests and one event, interpreted as a cavity collapse, that occurred 8 minutes after the declared test. We also analyze two earthquake events that occurred to the south and were recorded by the same set of stations. We perform a grid search...
