【摘要】 介绍了闽、台地震台网及观测资料情况,统计了1971年以来两台网均有测定的在台湾及其邻近海域地区发生的6级以上地震,并计算了福建地震台网测定近震震级范围、闽台两地震台网测定震级的差量、平均偏差及标准偏差。结果表明,福建地震台网测定台湾及其邻近海域地区强震震级普遍偏小,存在0.3~0.5级的偏差。进而分析了闽、台地震台网测定台湾强震震级的差异关系,对福建地震台网测定台湾及其邻近海域强震震级偏差改正及闽、台今后开展地震联合观测有重要参考价值。更多还原

【Abstract】 The situation of Fujian and Taiwan seismic networks and their data has been briefly introduced.We collected Taiwan and adjacent sea earthquakes(M≥6.0)recorded by Fujian and Taiwan seismic networks from 1971,and analyzed the range of magnitude determined by Fujian seismic network and magnitude deviation,mean deviation and standard deviation between determined by Fujian network and by Taiwan ’s.The result shows M0.3-M0.5 less deviation of Taiwan and adjacent sea macroseisms magnitude determined by Fujian seismic network.And then we analyzed the difference relation between macroseisms magnitudes determined by Fujian seismic network and by Taiwan network.It is an important reference for Taiwan and adjacent sea macroseisms magnitude correction determined by Fujian network and joint observation of Fujian and Taiwan networks.更多还原
