Keywords:Landslide, Sedimentary rocks, Main Central Thrust

In 11 Nov 2022, we surveyed outcrop and landslide body of deep-seated landslides around Probi Village (84°19'51″E, 28°20'16″N), right bank of Khudi River and at Sarin Village (84°21'33″E, 28°15'18″N), right bank of Marsyangdhi River, Where is around Main Central Thrust (MCT). Geology is metamorphosed sedimentary rocks. On these sites landslide surface deformations were observed by InSAR analysis using PALSAR-2 data (Path158, Frame560). We will comapare the result of the field survey with the deformation detected by the data, then discuss that the detected deformation is well explained by the phenomena observed by the field survey.
