%X The landslide mass at Nangou, Yan'an City, is situated within a typical Loess Plateau landscape, characterized by loess hills and gullies. This area exhibits significant topographic relief and is highly prone to frequent geological hazards, such as landslides, with distinct regional developmental patterns. The landslide area is blanketed by thick Quaternary loess, known for its high porosity and permeability. This structure makes it particularly susceptible to external hydrological factors like rainfall, which can significantly alter its physical and mechanical properties and thereby reduce the overall stability of the slope.To reveal the internal geological structure of the landslide, three survey lines were established across the site. A combination of passive and active surface wave methods was employed to obtain a high-resolution profile of the shallow shear wave velocity (Vs). This data provides critical support for subsequent analysis of the landslide mechanism and stability assessment.
