| Abstract: | On 27 March 2021, a landslide with a volume of approximately 2?×?104 m3 occurred in Guocun Village next to Kengheng road in Tonglu County, Zhejiang Province, China. The landslide caused no casualties as a result of timely road closures, because of the unusual noises detected early by local residents. The motion mechanism of the landslide was studied using video analysis. Slope cutting resulting from road construction might have been the major triggering factor for the landslide. The intrusion of magma and the uplift process of Huangshan led to the metamorphism of mudstone to easily fractured slate, and the brittle layered slate might have controlled the change of motion from transitional sliding to dry debris flow. |
