National-scale rainfall-triggered landslide susceptibility and exposure in Nepal

This dataset is a 30 m resolution landslide susceptibility (hazard) model for Nepal. The dataset is derived from a fuzzy-logic model following the approach developed by Kritikos et al (2015), and is trained on a manually mapped landslide inventory (polygons of landslide locations and extents), originally produced by Durham University and NSET Nepal as part of the UKRI-DFID SHEAR program. The dataset shows the relative probability of a landslide occurring across the geographical extent of Nepal for rainfall triggered landslides only, on a scale of 1 (very highly anticipated) to 0 (very weakly anticipated). Further details and an online map viewer containing the data are available through the Bipad portal (https://bipadportal.gov.np/risk-info/#/hazard).

The research relating to this landslide susceptibility model has been supported by the UKRI-DFID SHEAR program (201844-112), the EPSRC project ‘Risk at the Margins’ (EP/T024747/1), the EU ECHO HIP project ‘Risk informed landslide management in Nepal’s hill areas’ (ECHO/-XA/BUD/2020/91026), and by a grant from the Global Challenges Research Fund Multi-Hazard and Systemic Risk programme for the ‘Sajag-Nepal’ project (NE/T01038X/1).
