“…This has become an effective tool for continuous monitoring of deep open-pit slope movements, significantly reducing the probability of slope geological hazard occurrences. Xie et al [13] set up an MS monitoring network for a slope project in the Three Gorges Reservoir Area. Their findings revealed that under creep deformation, the shallow rockslides exhibit a failure mechanism characterized by leftlateral normal fault shear failure.…”

Assessing the stability of rocky slopes with faults presents a major engineering challenge in construction projects. The steeply inclined faults and rock joints significantly impact the left bank slope of the Jinchuan Hydropower Station in the outlet field, resulting in highly complex geological conditions that raise significant concerns regarding slope stability throughout construction and operation. Microseismic(MS) monitoring and numerical simulation are used to reveal the evolution mechanism of rock mass from fracture to deformation during slope excavation and unloading. The results show that the MS activity can well reveal the influence of slope construction disturbance on geological structure damage and structural plane activation. Specifically, the g7 fault as a critical factor influencing the failure mode of the left bank slope of the Jinchuan Hydropower Station in the outlet field. The comparison of monitoring data, numerical simulation, and in-situ failure shows that the deformation area of rock mass is consistent with the damage area defined by MS monitoring, which confirms the accuracy of MS monitoring and numerical simulation results. These research findings can serve as a basis for the later-stage construction of the dam foundation slope at the Jinchuan Hydropower Station and offer guidance for the stability assessment of similar slope engineering projects.

This paper gives an account of the diverse dimensions of research on disaster risk reduction in mountain regions derived from an open call of the Journal of Mountain Science that brought 21 contributions. This special issue includes topics as diverse as landslide dynamics and mechanisms, landslide inventories and landslide susceptibility models, insights to landslide hazards and disasters and mitigation measures, disaster response and disaster risk reduction. The overall structure of the paper takes the form of three sections. The first part begins by laying out the significance of disaster risk reduction in mountain areas, whereas the second one looks at the research insights on disaster risk reduction in mountains provided by the contributions comprised in the special volume. The final section identifies areas for further research.
