【摘要】 通过对青藏高原北部地区前兆观测手段共88个台点的资料系统分析、整理、汇总,认为在昆仑山口西8.1级地震中短期内前兆异常具有明显的特征,并认为8.1级地震的发生不仅仅是大构造断裂带活动的产物,更是在某种特殊的力源作用下,大区域构造应力发生显著变化,并在几条边界构造大断裂的相互作用下发生的1次强震活动。更多还原

【Abstract】 The data of precursory items recorded by 88 stations in the western Qinghai-Xizang plateau are analyzed. The results show that the precursory anomalies appeared obviously characteristics in middle-short term before the earthquake with Ms8.1,and this earthquake is not only caused by the activity of great-deep fault zone, but also by a special mechanical source, and by the interaction in several boundary stractural faults in this area.更多还原
