摘要
本文讨论了太阳黑子活动,地球自转运动。大气降水和气压等环境因子与帕米尔及其邻近地区(新疆部分)大震活动的关系,进行了相关统计分析,在α=0.05置信水平的统计检验是显著的。认为,环境因子与大震活动存在着较好的相关关系,地震的孕育不仅是由于地壳内部应力的积累和调整,而且还有地球外部的地震环境因子的调制和触发作用。
The relationship between the strong earthquake's activity and the environmental factors have been analysed. In this paper, we tried to find the correlation of the large earthquake's activity of Pamir and its nearby regions with the environmental factors, such as the sunspot's activity; the rotation of the earth , the atmospheric precipitation and the atmosphric pressure, etc.. The statistical examination of confidence level α = 0.05 is obvious. A good correspondence between the enviromental factors and the large seismic activities could be found in the region, which shows that the potential for earthquake occurrence is not only due to the accumulation and adjustment of the stress within the crust, but also the trigger and modulation functions of the enviromental factors coming from outside of the earth.
