The ISC Contribution to Monitoring Research
Abstract
The International Seismological Centre (ISC) is a non-governmental organization charged with production of the ISC Bulletin - the definitive global summary of seismicity based on reports from over 4.5 thousand seismic stations worldwide. The ISC data have been extensively used in preparation of the Comprehensive Test Ban Treaty (CTBT). They are now used by the CTBTO Preparatory Technical Secretariat (PTS) and the State Parties as an important benchmark for assessing and monitoring detection capabilities of the International Monitoring System (IMS). The ISC also provides a valuable collection of reviewed waveform readings at academic and operational sites co-located with the IMS stations. To improve the timeliness of its Bulletin, the ISC is making a special effort in collecting preliminary bulletins from a growing number of networks worldwide that become available soon after seismic events occur. Preliminary bulletins are later substituted with the final analysis data once these become available to the ISC from each network. The ISC also collects and maintains data sets that are useful for monitoring research. These are the IASPEI Reference Event List of globally distributed GT0-5 events, the groomed ISC bulletin (EHB), the IDC REB, USArray phase picking data. In cooperation with the World Data Center for Seismology, Denver (USGS), the ISC also maintains the International Seismographic Station Registry that holds parameters of seismic stations used in the international data exchange. The UK Foreign and Commonwealth Office along with partners from several Nordic countries are currently funding a project to make the ISC database securely linked with the computer facilities at PTS and National Data Centres. The ISC Bulletin data are made available via a dedicated software link designed to offer the ISC data in a way convenient to monitoring community.
