ISC data products, in particular the global catalog of observed arrival times, amplitudes, and associated meta data, are a starting point for fundamental studies of Earth structure and earthquake source mechanisms. The Bulletin also aids in monitoring of the Comprehensive Test Ban Treaty. The ISC Bulletin supports the global seismology community for fundamental research on Earth structure, earthquake physics and earthquake hazards mitigation. The international supported and non-governmental affiliation of the ISC allows the Centre to collect and freely distribute data from otherwise unavailable sources of global seismic recordings. Support provides for continued production of the ISC Bulletin - the definitive global summary of earthquake hypocentres, magnitudes and source mechanisms, as well as station arrival times, amplitudes and other measurements with links to original waveforms where available. near 20% of the estimated operational costs over this period. The ISC is internationally supported and the requested budget is based on the relative GDPs of sponsor countries with funding from the U.S. This grant allows for renewed partial support of operations of the International Seismological Centre (ISC).
