摘　　要：以ISCloc为核心方法和技术,ISC统一分析处理全球的观测数据并定期出版地震观测报告。从资料收集、数据关联、定位方法和技术、数据分析与出版4个方面阐述ISC观测报告产出的主要过程。2008年后,ISC每年汇集300000—500000次以上地震,其中约20%的地震需要地震学家分析和审核,观测报告发布、出版时间比实际地震发生时间滞后约24个月。The global observational data are uniformly processed based on ISCloc as the main method and technique,and the seismic observation bulletins are regularly produced in ISC.The principal procedure of the bulletin production was detailed illustrated from 4 aspects:data collection,data associations,location method and technique,data analysis and publication.There are more than 300000-500000 events collected in ISC per year after year 2008,and nearly 20% of those need to be analyzed and reviewed by seismologists.The issue and publication of bulletin data are typically 24 months behind real-time.
