【摘要】 通过对1950年以来中国大陆5级以上原地(区)连发地震组的空间特征研究,发现各个时期的原地(区)连发地震组具有填充的特征,各个时期都存在主体活动区域,并且与7级地震活动关系密切。依据以上特征,可对今后中国大陆发生7级以上地震和5级以上原地(区)连发地震组的发震区域提供判定参考,在地震活动性分析上也是一种新的尝试,有待于时间的检验。更多还原

【Abstract】 Through studying spatial feature of the in-situ continuously occurred M5.0 earthquakes in China’s mainland since 1950, we have found that there is property of filling in gap of group earthquakes in situ for each periods, and there are areas of main activity in each period and there is close relation between the in situ continuously occurred M5.0 earthquake and the M7.0 earthquakes. Based on the characteristics, we can provide reference for determining areas of M7.0 earthquakes and the in situ continuously occurred earthquakes with M5.0 in Chinas mainland in the future. It is a new attempt in seismicity analysis, and needs time to be verified.更多还原
