摘要: 对1971年后中国大陆发生的5级以上地震进行了时空成组特征的统计分析, 结果表明1997~ 2001年我国大陆5级以上地震时空成组数所占比例较高; 在空间分布上, 1997年后我国大陆105°以西地区5级以上地震的时空成组性较好。以上研究结果有助对于我国西部5级以上地震的中短期预测。

Abstract: Statistic analysis about time and space grouping features of earthquakes with M≥ 5 occur red in China's continent since 1971 have been made. It has showed that from 1997 to 2001, the proportion of time and space grouping number of earthquakes with M≥5 occurred in our continent is relatively high. In space distribution, time and space grouping of earthquakes with M≥ 5 occurred to west of 105°in our continent after 1997 is relatively better. The results of the above-mentioned analysis are helpful to the medium-and short-term prediction on earthquakes with M≥ 5 in western part of our country.

Key words: Grouping activity, Statistical analysis, Time and space distribution, China′s continent
