Slope Deformation caused Jure Landslide 2014 Along Sun Koshi in Lesser Nepal Himalaya and Effect of Gorkha Earthquake 2015

Although there is no commonly accepted methodology for evaluation of deep-seated landslide susceptibility, the progress on remote sensing technology such as aerial photos, satellite images, precise DEM and InSAR data have made it easier to detect ground movement at time interval and cost-effective. Combining these techniques and ground truth, the authors attempt to understand the nature of Jure landslide in Nepal that occurred due to heavy rain in August 2014. They have also studied the effect of Nepal Gorkha earthquake on the Jure landslide. Gravitational deformation, so-called “rock creep” has proceeded for long time forming thick weathering layer at the Jure landslide site. Small and shallow deformations have occurred in and around the site since a decade or before. However, significant enlargement of the landslide due to the earthquake in 2015 was not detected by InSAR because the quake occurred at the end of dry season.
