[S06-1-02] The ISC datasets for monitoring research
The International Seismological Centre (ISC) is a non-governmental organization based in UK and funded by 69 research and operational institutions in 45 countries. The main mission is to produce the global definitive Bulletin of earthquakes and other seismic events based on reports from over 130 seismic networks worldwide. The ISC Bulletin is the most long-term and comprehensive source covering the period from 1904 to 2017.
Soon after seismic event occurrence, the ISC collects preliminary bulletin reports from various seismic networks and agencies around the world. Once integrated together, they form a bulletin of very recent global seismicity. These preliminary reports are later substituted, one by one, with fully reviewed reports from the same agencies and form the basis for the comprehensive and reviewed ISC Bulletin. Thus, at any time with respect to each seismic event occurrence, the ISC Bulletin remains a great reference source of information for various studies of monitoring product's completeness, quality and calibration.
In addition, the ISC maintains and distributes several derivative datasets that are used in monitoring research: the ISC-EHB bulletin - a groomed subset of the ISC Bulletin containing well-recorded teleseismic events; the IASPEI Reference Event List (GT) – a bulletin of events for which the hypocentral information is known with high confidence (to 10km or better); the ISC Event Bibliography - an interactive facility that enables searches for references to scientific articles devoted to specific natural and anthropogenic seismic events that occurred within a region and time period of interest.
Here we describe major advances recently made by the ISC to extend and improve these datasets that are openly available and widely used in monitoring research. These datasets are also used by the ISC as a basis of its interactive service “The CTBTO Link to the ISC database" used by the personnel of many National Data Centres.
