2021年博士毕业于中国科学院大学，之后在分别在香港中文大学和瑞士联邦森林、雪和景观研究所从事博士后研究，研究方向为地质灾害动力学与环境地震学，主要基于地震信号观测，反演和评估滑坡与泥石流等地质灾害的动力学机制，研究地震与地质灾害相互作用机制。以第一作者在Nature Communications, Geophysical Research Letters, Journal of Geophysical Research: Solid Earth等自然指数期刊发表多篇论文。

报告简介：

Approximately 12% of the global population resides in mountainous regions that are highly vulnerable to hazardous mass movements and their cascading effects. Effective management of geological hazards requires a deep understanding of the complex physical mechanisms driving these events and their interactions. Recent advancements have demonstrated that seismometers can provide real-time data on geomorphic processes and hazards, even from remote locations. Here, I will present my research on utilizing seismic signals to investigate the dynamics of two common types of mass movements—landslides and debris flows—and their cascades. While hazard cascades triggered by earthquakes are typically conceptualized as linear chains, such as the sequence of earthquake-landslide-dammed lake-outburst flood, our findings suggest that landslide-dammed lakes can, in turn, trigger seismic activity. These results emphasize the potential of seismological techniques not only for studying mass movements but also for offering new insights into the bidirectional interactions between earthquakes and mass movement processes.
