According to the detailed study of the historical earthquake records and causative structure of the Minxian M6 1/2 earthquake in 1573 A.D., we have found that the most grievous disaster area lies nearby the Minxian county seat （Minzhou county at that time ）. So, we have identified the extremely seismic area of the 1573 A.D. The Minxian M6 1/2 earthquake was located in Minxian city, the intensity of the meizoseismal region is Ⅷ - Ⅳ, the epicenter is 34.4°N, 104.0°E, the location precision is Ⅱ and the deviation of location is less than or equal to 25km. Tectonically, this area lies in the transition region of stress transfer and structural transform between the east Kunlun fault and the northern margin of the west Qiuling fault. The differential activity of the Lintan-Dangchang fault zone is obvious, and only parts of the segment put up Holocene activity. There are landslides and rock bursts of different sizes in the meizoseismal region. By integrated analysis, we conclude that the Minxian-Dangchang segment of the Lintan-Dangchang fault is the seismogenic structure of the 1573 A.D. M6 1/2 Minxian earthquake, in Gansu Province.

The 1927 Gulang M_S8.0 earthquake is a severe earthquake that followed the Haiyuan M_S8.5 earthquake of 1920 in the Qilian Mt._Hexi Corridor earthquake zone. There are divergences of opinion in the previous studies about the rupture properties of the earthquake. Based on trenching and field investigation, and analysis of historical data, we hold that the earthquake resulted from the joint process of the Tianqiaogou_Huangyangchuan fault, Dongqingding segment of the Huangcheng_Shuangta fault and the Wuwei_Tianzhu buried fault, which constitute the Gulang nappe. By finite_element numerical simulation on the deformation mechanism of Gulang nappe, it is found that the stress and strain mainly concentrate in the western segment of the Tianqiaogou_Huangyangchuan fault, the Dongqingding segment of the Huangcheng_Shuangta fault, and the Gulangxia segment of the Wuwei_Tianzhu buried fault and the Gulang_Shuangta fault. The stress concentration coincides with the distribution of the earthquake surface rupture. It also proves that the earthquake is an outcome of the Gulang nappe activity as a whole.

龙陵—澜沧新生地震断裂带位于地震活动强烈的滇西南地区,该地区历史上曾发生多次MS≥7.0大地震,已知的历史地震破裂几乎覆盖了整条断裂带.本文首先对滇西南地区主要断裂的最新构造活动特征进行分析;然后通过该区域地震活动b值图像的空间扫描计算,圈定出高应力集中区,并结合历史地震和现今小震的分布情况以及晚第四纪以来断裂的活动强度、古地震最晚离逝时间等定量参数,综合分析龙陵—澜沧断裂带的未来大震危险性;最后基于地震空区理论,识别该断裂带存在的地震空区.研究结果表明,龙陵—澜沧断裂带内的龙陵、永德、沧源、澜沧及孟连断裂中东段在未来10年内均存在发生中强以上地震的危险性,应引起关注.

受祁连山北缘断裂和广义海原断裂等构造活动的控制和影响,祁连山东段发育了由多条挤压逆冲断裂组成的古浪推覆体构造,形成地貌起伏大并向北逐级降低的独特构造地貌特征。本文基于ArcGIS空间分析技术,利用数字高程模型(DEM)系统提取了祁连山东段(造山带内部与河西走廊盆地)的宏观地貌因子(如面积—高程积分和条带状剖面)并综合分析其所蕴含的地质意义。研究结果表明,区域地貌演化过程主要由构造变形控制,而并非岩性差异和降雨条件等因素。研究区内的皇城—双塔断裂、冷龙岭断裂以及武威盆地南缘断裂所控制的古浪推覆体具有较高的HI值,龙首山东段的河西堡—四道山断裂南侧显示HI高值、北侧显示HI低值,表明祁连山东段存在由南向北的挤压扩展演化过程,这可能与祁连山北缘大断裂向北的扩展以及阿拉善块体向南俯冲作用有关;提供了祁连山东段向河西走廊内部挤压扩展的地貌证据。

活动构造是影响地质灾害发生的主要因素之一.利用SRTM-3数字高程模型(digital elevation model,简称DEM)数据,基于ArcGIS空间分析技术及Matlab程序脚本系统提取白龙江流域宏观地貌信息、拟合流域内部7个4级亚流域的S-A图解,并结合流域内部新构造特征、活动断裂分布、岩性展布特征以及降水条件等系统分析了白龙江流域滑坡泥石流地质灾害发育的控制因素.其中,S-A拟合图形上凸者代表流域内物质的输出量大于输入量,反之,S-A拟合图形下凹者代表流域内物质的输出量小于输入量,而物质输入表现为山体隆升,较大的物质输出量具体表现形式即为突发事件形成的滑坡、泥石流灾害;另外区域构造运动控制下的强烈褶皱破碎甚至糜棱化或半糜棱化岩层分布也是地质灾害发生必不可少的条件.受上述因素综合影响,本区地质灾害通常发生在高程突变、起伏度与切割深度大的高坡度分布区,而由于区域差异隆升所形成的不同的亚流域地貌形态则控制了地质灾害高发区,即物质输出量大于输入量的亚流域内部滑坡泥石流等地质灾害频繁,而输入量大于输出量的亚流域内部并无明显地质灾害分布点.

A detailed investigation permitted us to obtain quantitative data concerning fine geometric structures of 4 faults of the active Maxianshan-Xinglongshan fault system and the latest movement along them. Of them the northern Maxianshan border fault is a large-scale, strongly active Holocene reverse sinistral strike-slip fault, the other 3 faults, the southern Maxianshan border fault and the southern Xinglongshan border and the northern Xinglongshan border faults are the accompanying active late-Pleistocene thrust faults, which are incorporated into the main strike-slip fault, the northern Maxianshan border fault at depth. It is the most important earthquake-controlling fault in the Lanzhou area, the fault influences and constrains the seismic activity in the area.
