摘要
本文揭示了西双版纳州东、西两部分地震(以谰沧江为界)的交替活动性,强震的近似原地重复性以及与环境因子的关系,进而指出本世纪90年代中至21世纪初该州的强震危险区主要在勐海县周围。最后,为实现逐年跟踪逼近预测,又提出了一种根据大气降水对地壳的加卸载动态变化具体判断发震年份的方法。
Alternative seismicity between the eastern and western Xishuangbanna Prefecture (bounded by Lancangjiang River), approximate recurrence of strong earthquakes and their relation to the environmental factors have been revealed in this paper. Furthermore, it is indicated that the risk of strong earthquakes from the middle 1990s to the beginning of 21st century will be around Menghai county. In order to trace the annual prediction, a method for determining the earthquake - occurring year is presented according to dynamic variation of loading and unloading of atmospheric precipitation on the crust.
