本文介绍并分析了中国地震观测台网及各速报台站目前速报震级的现状,存在的问题及原因,并利用1984、1985两年速报震级资料,统计分析了中国地震观测台网确定震级的精度及各速报台相对全国地震台网测定震级的偏差,同时也统计分析了全国地震台网相对地球物理所临时报告和美国地质调查所震中初定报告(PDE)的震级的偏差。并对所得结果进行了初步的讨论。
This paper introduces and analyzes the current situation, existing problems and causes of earthquake magnitude in China Earthquake Observatory Network and each station, and makes use of the data of earthquake magnitude in 1984 and 1985 to make a statistical analysis of the determinations of China Earthquake Observatory Network The accuracy of earthquake magnitude and the deviation of the magnitude of each station from that of the national seismological network. Meanwhile, the magnitude of the earthquakes in the relative geophysical reports of the national seismographic network and the preliminary report of the U.S. Geological Survey (PDE) was also statistically analyzed. The preliminary results are discussed.
