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。 This article through geological geomorphology, radon gas measurement and other means, on the Wangqing M6.6 1902 earthquake events and the Tumen River. In the basin, the neotectonic movement was investigated and re-examined. The macro epicenter of Wangqing M6.6 Earthquake in 1902 was re-identified (longitude 129 ° 24, latitude 43 ° 26); the NW-direction compressive shear fault of Dongyang dome was determined as active fault, It is the seismogenic structure that occurred on July 3, 1902, with a magnitude 6.6 earthquake. The principal compressive stress near the fault is near east-west.
