Sampling the topsoil at the locations where landslides occurred in Keelung City, compared the topsoils of different slope directions in the school, to understand the characteristics of the soils that have occurred in the past landslides. The surface soil of the landslide site is mostly coarse-grained sandstone, mostly facing the northeast, and the strata under the surface are mostly sedimentary rocks. The time of landslides is mostly winter to spring, which is the rainy season in Keelung City. Accroding to the spectrum of the sampled soil images, it is found that the surface soil in this area usually absorbs more long waves. Traditionally, precipitation is used to monitor where landslides may occur. If monitoring of surface soil can be added, the chances of preventing landslides can also be improved
