【摘要】 本文通过地质地貌、氡射气测量等手段，对 1902 年汪清 6.6 级地震事件和图们江。流域新构造运动进行调查研究，重新认定了 1902 年汪清 6.6 级地震的宏观震中位置 ( 东经 129 ° 24， 北纬 43 ° 26 )； 确定了东阳穹房沟 NW 向压剪性断裂为活动性断裂，是发生 1902 年 7 月 3 日 6.6 级地震的发震构造。该断裂附近的主压应力方向为近东西向。更多还原

【Abstract】 Features of the Wangqing 6.6 earthquake occurred in 1902 and the tectonic activity in the Tumenjiang valley are studied in this paper by means of geology, geomorphology and Rn radiation. The macroscopic epicentre is determined to be at 12924E,4326N. The NW fault in Qiongfanggou is determined active and to be the seismogenic structure for the 6.6 earthquake. The principal compressional direction in the fault area and nearby is E-W.更多还原
