1黄土地震滑坡形成机理研究的若干进展显示文摘地震滑坡是黄土高原较为严重的一种地震地质灾害。在简要回顾黄土高原历史特大地震诱发黄土滑坡灾害特点的基础上,从地震强度、断裂构造、地形地貌、地层岩性、土层结构以及水文地质条件等6方面归纳了黄土地震滑坡的影响因素和发育特征,总结了液化型、剪切型以及震陷型等3种黄土地震滑坡形成机理的研究进展,探讨了黄土与非黄土地震滑坡形成机理间的异同,给出了进一步开展地震黄土滑坡形成机理研究的建议。颜灵勇 李孝波 欧阳刚垒 2021防灾科技学院学报2021,23,2:4

3Landslides Triggered by the 2020 Qiaojia M_(w)5.1 Earthquake, Yunnan, China: Distribution, Influence Factors and Tectonic Significance显示文摘On May 18, 2020, an M_(w)5.1 earthquake occurred in Qiaojia County, Yunnan Province, China. This moderate-sized event triggered massive coseismic landslides, resulting in some damage. In this work, through visual interpretation of high-resolution(0.8–2 m) Gaofen satellite images before and after the earthquake, 167 landslides were delineated, 18 of which were inspected in the field. Using the landslide number density(LND) and landslide area percentage(LAP), we characterized the spatial distribution of these landslides, and analyzed their possible influence factors and tectonic significance. The results show that these landslides are distributed mostly in the NW-SE direction, roughly parallel to the long axis of seismic intensity zones and the strike of the Xiaohe-Baogunao fault(XBF). The LND and LAP decrease with increasing distances to the fault and from the epicenter to fault ends of the XBF. These permit to suggest that the seismogenic fault of the Qiaojia earthquake is likely a hidden branch of the XBF. All of the landslides induced by this event occurred in the region with the seismic intensity of six degrees or greater of the 2014 M_(w)6.2 Ludian earthquake. Therefore, it was inferred that the 2020 Qiaojia earthquake was probably the subsequent release of accumulated elastic strain after the 2014 Ludian earthquake in a same tectonic stress regime.Xiangli He Chong Xu Wenwen Qi Yuandong Huang Jia Cheng Xiwei Xu Qi Yao Yongkun Lu Boyang Dai 2021Journal of Earth Science2021,32,5:2
4Preface to the Special Issue on Earthquake-Induced Landslides显示文摘Earthquake-induced landslides are the most destructive secondary geological hazards following large earthquakes that can destroy infrastructures and cause loss of lives and properties(Marano K.D.et al.,2010;Xu Chong et al.,2018).In the past few decades,earthquake-induced landslides have captured growing interests of both scientific communities and the public;more and more studies have been carried out(Xu Chong et al.,2010;Xu Chong,2018;Fan Xuanmei et al.,2019).To demonstrate the state-of-the-art on related research,we presented a special issue on earthquake-induced landslides.This special issue includes six columns,including inventory and spatial distribution,hazard assessment,numerical calculation and simulation,shaking table test,early warning,and evolution of earthquake-induced landslides,as well as a few studies about nonseismic landslides.XU Chong JIANG Yuanjun LIU Chun LU Heng 2020Earthquake Research in China2020,34,1:0
