It has been 15 years since the catastrophic 2005 Kashmir Mw 7.6 earthquake induced thousands of landslides in northern Pakistan and Kashmir. There have been many studies on various aspects of the landslides triggered by the earthquake, such as the mechanisms of individual large landslides, regional seismic landslide inventory mapping, spatial distribution pattern, susceptibility and hazard assessment, and landslide evolution, which provide beneficial scientific results. However, there is currently no summary and generalization of these studies for ready use of the researchers to fully understand the information of the landslide caused by the earthquake. This study comprehensively reviews and summarizes the important results obtained from published data on the landslides. The seismogenic and regional active faults, fragile lithological condition, heavy rainfall, anthropogenic activities, and steep terrain were considered as main controlling factors for the landslide occurrence. Studies on landslide evolution reveal that vegetation on most of the landslides was partially recovered after the earthquake, while slope failures along roads and drainages increased. In the affected area, landslides are still a great threat to communication networks and communities. Despite many past studies, there is still a need or in-depth research using more precise methods to understand the mechanism, hazard, and risk assessment, numerical simulation, landslide risk management and mitigation, and continuous or temporal monitoring of landslides in the affected area. Combined with high-quality data on landslides triggered by other earthquake events in recent years, the study points out the prospects of Kashmir earthquake-induced landslides and summarizes the future challenges of earthquake-triggered landslides research, including accuracy of inventories, the precision of landslide, susceptibility methods, prevention and control of landslide, and landslide hazards and risk assessment. This review can provide a reasonable scientific research and disaster prevention and mitigation strategy and scheme for landslides triggered by a large earthquake in the future.

回顾与2005年克什米尔地震有关的滑坡:影响和未来挑战

自从2005年克什米尔Mw 7.6灾难性地震在巴基斯坦北部和克什米尔发生数千起滑坡以来,已经过去了15年。对地震引发的滑坡的各个方面进行了许多研究,例如单个大滑坡的机理,区域地震滑坡清单制图,空间分布模式,易感性和危害评估以及滑坡演化,这些都提供了有益的科学结果。但是,目前尚没有这些研究的总结和归纳,以方便研究人员充分了解地震引起的滑坡信息。这项研究全面回顾并总结了从已公布的滑坡数据中获得的重要结果。地震活动和区域活动断层,脆弱的岩性条件,暴雨,人为活动和陡峭的地形被认为是滑坡发生的主要控制因素。对滑坡演化的研究表明,地震后大部分滑坡的植被得到了部分恢复,而沿道路和排水沟的边坡破坏增加了。在受灾地区,滑坡仍然是对通信网络和社区的巨大威胁。尽管有许多过去的研究,但仍需要或需要使用更精确的方法进行深入研究,以了解其机理,危害和风险评估,数值模拟,滑坡风险管理和缓解以及对受灾地区滑坡的连续或时间监测。结合近年来其他地震事件引发的高质量滑坡数据,该研究指出了克什米尔地震诱发的滑坡的前景,并总结了地震触发的滑坡研究的未来挑战,包括清单的准确性,滑坡的精度,易感性方法,滑坡的预防和控制以及滑坡的危害和风险评估。这篇综述可以为将来由大地震引发的滑坡提供合理的科学研究,防灾减灾策略和方案。
