This study used multi-stage remote sensing data in the analysis of the evolution of deep-seated landslides at Putanpunas stream, Taiwan.Terrain analysis, landslide interpretation, and the assessment of underlying mechanisms were included.Our results show that the evolution of deep-seated landslides can be divided into four stages: (1) erosion and fr5299 decompression of the gully, (2) deformation of the rock slope, (3) the development of sliding surfaces, and (4) movement of the sliding mass.A large quantity of colluvium has enchanted taylor swift perfume accumulated on the slopes and in upstream and midstream gullies.In the future, we predict that the erosion of this colluvium will greatly influence the direction of flow and terrain in the alluvial fan.

This activity is also expected to threaten the safety of inhabitants and property in the area intersecting Laonong stream.
