Advances in earthquake and cascading disasters

Abstract

Earthquakes and cascading disasters have garnered increasing attention. The 2023 Annual Academic Conference of the Committee on Earthquake Hazard Chain, the Seismological Society of China, was successfully held in Beijing. The conference presentations and proceedings covered a wide range of topics beyond seismic disasters, including landslides, ground fissures, avalanches, freeze-thaw processes, land subsidence, dam-break floods, and multiple chain disasters, such as earthquake-landslide, rainfall-landslide-barrier lakes, earthquake-fires, and earthquake-tsunamis. The research directions addressed various aspects, such as disaster database development, formation mechanisms, spatial distribution, identification techniques, prediction methods, monitoring and early warning systems, hazard assessment, mitigation strategies, and post-disaster recovery and reconstruction. In this paper, we systematically categorize and review the conference presentations, focusing on the research status and recent advancements in three major areas: seismic disasters, earthquake-induced cascading disasters, and non-seismically triggered landslides. It aims to provide scientific references for theoretical studies and technological applications in disaster prevention, mitigation, and emergency response. In the future, we should integrate cutting-edge multidisciplinary technologies and theories, leverage data-driven approaches to build a comprehensive database of earthquake disaster chains, enhance precursor monitoring to improve accuracy, advance mechanism research, and develop robust risk assessment systems.
