| 摘 要： | 郯庐断裂带东北段依兰-伊通断裂历史上没有发生过6级以上地震,一般认为是第四纪早期活动断裂,为中强地震发震构造.通过高分辨率卫星影像解译和野外调查,在该断裂多个段落发现断错河流Ⅰ级阶地等全新世地貌面、高1～2m的地表陡坎.其中,在通河县附近的最新地表陡坎长约70km,舒兰附近的最新地表陡坎长约10km.分别对黑龙江通河县...

| Abstract: | No earthquake greater than M6 has been documented on the Yilan-Yitong Fault,and no trace of activity since the late pleistocene has been seen either at the northeastern section of the famed Tanlu grand fault zone in eastern China.Thus this fault is recognized active in the early Quaternary and capable of generating moderate quakes.By analyzing high-resolution satellite images and field work,a 70km-long geomorphic scarp in Tonghe County of Heilongjiang Province and a 10km-long geomorphic scarp in Shulan Coun... |
