[J09-2-06] The ISC Bulletin and the derivative datasets for Geoscience research
The International Seismological Centre (ISC) produces the global definitive Bulletin of earthquakes and other seismic events based on reports from over 130 seismic networks worldwide. The ISC Bulletin remains the most long-term and comprehensive source of information for global seismicity between 1904 and 2017. In addition to earthquake hypocentres and magnitudes, the historical period (before 1964) now contains seismic arrival times at stations from the International Seismological Summaries (ISS) and multitude of individual station bulletins digitized during the ISC-GEM project. The modern period (1964-onwards) is currently being updated, expanded and homogenized under the Bulletin Rebuild project.
To help users with different research needs/requirements, we also maintain and distribute several derivative datasets:
The ISC-GEM catalogue – the most homogeneous and complete record of moderate to large instrumentally recorded earthquakes over the last ~110 years; it was designed for use in global and regional assessment of seismic hazard.
The ISC-EHB bulletin - a groomed subset of the ISC Bulletin containing well-recorded teleseismic events with particular attention given to depth determination; it is widely used in studies of seismicity and structure of the Earth.
The IASPEI Reference Event List (GT) – a bulletin of events for which the hypocentral information is known with high confidence (to 10km or better); it is used for a variety of calibration purposes, especially in nuclear monitoring studies.
The ISC Event Bibliography - an interactive facility that enables searches for references to scientific articles devoted to individual natural and anthropogenic seismic events that occurred within a region and time period of interest; it is widely used in education and by scientific article authors, reviewers and journal editors.
We describe major advances recently made by the ISC to extend and improve these open-access datasets that are widely used in Geoscience research.
