Abstract

Seismic station VRAC operated by IPE (Institute of Physics of the Earth) is part of the International Monitoring System CTBTO (Comprehensive Nuclear-Test-Ban Treaty Organization). This monitoring system is built for verifi cation of the compliance with the Comprehensive Nuclear-Test-Ban Treaty. Station VRAC provided important registration of the nuclear explosions. Last explosions were carried out on the territory Democratic People’s Republic of Korea (DPRK), latest North Korean nuclear test was conducted this year (12. 2. 2013). Station VRAC recorded signal of all North Korean nuclear explosions. Registrations by stations of International Monitoring System, including station VRAC, significantly contributed to improving of the discrimination techniques, mainly to improving the discrimination between natural earthquakes and explosions based on the analyses of Ms and mb magnitudes.
