9506767 BOYD This research is to digitally scan seismic phase observations tabulated in the International Seismological Summary (ISS) and Bureau Central International Seismologique (BCIS) catalogs, use these observations to compute high quality hypocenters based on techniques developed within the last few years, make tectonic interpretations based on these relocated earthquakes, and make the digitized phase observations and the recomputed hypocenters available to interested research groups. The result will be a much more complete and accurate seismicity catalog, especially prior to 1964 when the WWSSN program was implemented, that can be used to understand deformation and seismic hazard within the U.S. and throughout the world. This research is a component of the National Earthquake Hazard Reduction Program. ***

这项研究是对国际地震学摘要（ISS）和国际中央地震局（BCIS）目录中列出的地震相位观测数据进行数字扫描，利用这些观测数据根据过去几年发展起来的技术计算高质量的震源，根据这些重新定位的地震进行构造解释，并将数字化的相位观测和重新计算的震源提供给感兴趣的研究小组。结果将是一个更完整和准确的地震活动目录，特别是在1964年WWSSN计划实施之前，可以用来了解美国和全世界的变形和地震危险。这项研究是国家减少地震危害计划的一个组成部分。＊＊＊
