With the continuous growth of the world's population and the gradual expansion of the spatial scope of human activities, engineering activities supported by technical and economic conditions have rapidly enhanced the degree of disturbance to the geological environment. The geo-hazards, induced by global climate change, earthquakes, and other factors, are causing the increased economic losses and casualties.The geo-hazards have occurred among all mountainous areas with human settlements and engineering activities on a global scale. Specifically, the areas with a high incidence of geo-hazards involve the Scandinavian Mountains, the Alps, the Apennines in Europe and the Rocky Mountains, Madre Mountains, Andes Mountains in the Americas, and the first island chain in the Western Pacific and the Qinghai-Tibet Plateau in Asia. And the landslides have become the typical geo-hazards with the highest frequency and the greatest loss.Notably, after three years of impoundment, the Vajont rockslide (Italy, about 2000 casualties) occurred on October 9, 1963. The rockslide rapidly displaced the impounded water (169 × 106 m3), partially along the opposite valley flank, the upstream valley reaches, and over the 276 m Vajont dams. Thus, this rockslide has become a turning point in the study of geo-hazards in modern times. So far, the related research directions include, but are not limited to, the early identification, the catastrophe mechanism, the risk assessment, and the prevention and control of geo-hazards. Additionally, the methods such as physical model testing, theoretical analysis, machine learning, and numerical simulations are applied to the specific cases.
