PARTIAL SUPPORT OF THE INTERNATIONAL SEISMOLOGICAL CENTRE

这笔拨款用于支持国际地震中心（ISC）的持续运作。ISC是国际支持的，所要求的预算是基于赞助国的相对国内生产总值，美国国家科学基金会的资金估计在未来四年中占ISC运营成本的21.4%。NSF将继续支持ISC公报的制作，该公报是关于震源、震级和震源机制的明确全球摘要，以及台站到达时间、振幅和其他测量结果，并在可能的情况下与原始波形相联系。该中心的国际支持和非政府地位使其能够从其他来源收集和自由分发数据。支持的具体任务包括：1)收集、自动合并和关联来自世界各地网络和数据中心的报告公告数据，包括NEIC、EMSC、USArray、JMA等；2)人工审查震源、相位读数以及几个网络同时报告的大约3.5级及以上地震的相关数据；3)通过网络搜索、ftp、cd - rom和印刷的ISC公报摘要等方式分发ISC公报；4)与美国丹佛市世界地震数据中心（USGS）合作，并与数字地震台网联合会（FDSN）协调，维护和加强国际地震台站登记；5)在IRIS DMC上建立ISC数据库和网络设施镜像；6)使用新开发的定位算法重新生成1960-2012年整个ISC公报。ISC公报支持全球地震学界进行地球结构、地震物理和减轻地震灾害的基础研究。《公报》还有助于监测《全面禁止核试验条约》

0949072StorchakThis grant supports continued operations of the International Seismological Centre (ISC). The ISC is internationally supported and the requested budget is based on the relative GDPs of sponsor countries with funding from the U.S. NSF estimated at 21.4% of the ISC operational costs over the next four years. NSF support will provide 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. The international support and non-governmental status of the ISC allows the Centre to collect and freely distribute data from otherwise unavailable sources. Specific tasks to be supported include: 1) collection, automatic merging and association of reported bulletin data from networks and data centers around the world, including NEIC, EMSC, USArray, JMA etc; 2) manual review of hypocentres, phase readings, and related data for events simultaneously reported by several networks approximately of magnitude 3.5 and above; 3) distribution of the ISC Bulletin by means of the web-search, ftp, CD-ROMs and the printed ISC Bulletin Summary; 4) maintenance and enhancement of the International Seismograph Station Registry jointly with World Data Center for Seismology, Denver (USGS) and in coordination with the Federation of Digital Seismograph Networks (FDSN); and 5) establishment of a ISC database and web facilities mirror at IRIS DMC; 6) re-production of the entire ISC Bulletin for 1960-2012 using a newly developed location algorithm. The ISC Bulletin supports the global seismology community for fundamental research on Earth structure, earthquake physics and earthquake hazards mitigation. The Bulletin also aids in monitoring of the Comprehensive Test Ban Treaty.***
