The 2018 “5.12” Wenchuan Earthquake was one of the most devastating seismic events in history, triggering tens of thousands of co-seismic landslides. In the years that followed, major earthquakes such as the Haiti Earthquake (2010), the Gorkha Earthquake in Nepal (2015), the Kaikōura Earthquake in New Zealand (2016), and the Turkey-Syria Earthquake (2023) have occurred, each causing significant geological hazards. The Wenchuan Earthquake occurred at the initial stages of the rapid advancements in Earth observation technologies, including satellite remote sensing. In recent years, the increasingly availability of observational data has laid a solid foundation for understanding the cascading hazards induced by earthquakes. The spatial-temporal evolution patterns, underlying mechanisms, and strategies for risk prevention and control of these cascading hazards have attracted significant global attention, leading to substantial research achievements. 
 

This symposium, marking the 17th anniversary of the Wenchuan Earthquake, aims to provide a platform for scholars worldwide who study earthquake-induced hazards chains. It seeks to summarize the impacts, mechanisms, long-term effects, and strategies for risk prevention and control related to strong seismic hazards chains on a global scale, addressing the severe challenges posed by these hazards.
 

This 6th International Symposium continues the legacy of our series on strong earthquake-induced cascading hazards, which began in 2009. Over the past 15 years, we have successfully held five high-level international conferences, providing an excellent platform for academic communication and cooperation. This series has significantly contributed to innovation and advancement in the field of global strong seismic cascading hazard research.
 

The theme of this symposium is "Mega Earthquake-Induced Geo-hazard Chain and Long-term Effects", which will focus on topics such as the mechanisms and prediction of earthquake-induced geological disaster chains. We hope to bring together experts and scholars from around the world in the field of strong seismic geological disaster chain research, to engage in in-depth discussions and exchanges, thereby promoting international cooperation and advancing global research on strong seismic geological disasters.
