ABSTRACT

The International Monitoring System (IMS), part of the verification regime of the ban on nuclear explosion testing (Comprehensive Test Ban Treaty, CTBT), has been in the process of build up and  of provisional operation for about 10 years. The IMS includes two networks of globally distributed seismological stations and a data center (International Data Center, IDC), where all recorded station data are collected, processed, and analyzed. The IDC processing of station signal detections, formation of events, and event locations is fully automatic and is followed by a manual review. The first results of the automatic processing are distributed to States Parties to the CTBT about two hours after the occurrence of events. Apart from a brief review the processing and analysis procedures at the IDC we also discuss estimates of the current capabilities of the IMS to detect and locate seismic events.
