 This paper examined the effects of rainfall on landslides in the southeastern region of China. It was found that the majority of landslides occurred in Shiatsu town, where the gradient of the hill slopes distance from rivers, and total rainfall were all important factors. Additionally, the lithology and rainfall characteristics played a role in determining the abundance of landslides. Finally, numerical simulations showed that the heavy rain on May 8th was the main cause of the massive landslides. This article was authored by Ciyun Ma, Xiaoyishao, and Chongsu.
