Abstract

Seismological monitoring is one of the four technologies used by the International Monitoring System to verify compliance with the Comprehensive Nuclear-Test-Ban Treaty. When fully operational, two seismic networks, one primary (50 stations) and one auxiliary (120 stations), will enable global detection and event characterisation of sources with equivalent magnitude as low as 4. The basic principles of seismological theory and practice applied to verification are summarised below, with particular emphasis on the new requirements imposed by the needs of the Treaty.

Abstract

Die seismologische Überwachung ist eine der vier Technologien, die vom Internationalen Überwachungs-System zur Kontrolle der Einhaltung des Umfassenden Verbots von Nuklearversuchen verwendet werden. Im Endausbau werden zwei seismologische Netze, ein primäres (50 Stationen) und ein sekundäres Netz (120 Stationen), die weltweite Detektion und Charakterisierung von Ereignissen ab einer Stärke von Magnitude 4 ermöglichen. In diesem Beitrag werden die grundlegenden Begriffe seismologischer Theorie und Praxis zusammengefasst. Die sich aus dem Vertrag ergebenden neuen Anforderungen werden dabei besonders berücksichtigt.
