    This is a polygon shapefile inventory of 183 coseismic and climate-triggered landslides in the south-western portion of Langtang Valley Nepal. All mapped landslides were those visible in the landscape during the period 2017 – 2018. Landslides were mapped using a combination of field and remote sensing methodologies (see lineage). The inventory includes the landslide locations, perimeters (Length field), areas, types, and whether a given landslide was mapped in the field or remotely. These landslides were mapped for a range of purposes, from conducting landslide susceptibility assessments, to investigating landslide processes and preconditioning.

    Polygon shapefile including 481 coseismic and climate triggered landslides mapped along the Arniko Highway, Nepal, using a combination of field mapping and remote sensing. All mapped landslides were those visible in the landscape during the period 2017 – 2018. Landslides were mapped using a combination of field and remote sensing methodologies (see lineage). The inventory includes the landslide locations, perimeters (Length field), areas, types (for field mapped landslides), and whether a given landslide was mapped in the field or remotely (source field). These landslides were mapped for a range of purposes, from conducting landslide susceptibility assessments, to investigating landslide processes and preconditioning.

    Text file containing the areas (of combined scar, deposition and runnout zones, and estimated scar zones alone) and volumes (for both total and scar areas) of 12,920 Asia Summer Monsoon (ASM) that occurred across central-eastern Nepal in the period 1988 - 2018. Note, landslides were not mapped in the years 2011 and 2012 due to scan line errors in Landsat 7 imagery.

    Information for this layer of the map based index (GeoIndex) is taken from the BGS National Landslide Database (NLD), which holds over 15000 records of landslides and is the definitive source of landslide information for Great Britain (excludes Northern Ireland, Isle of Man and the Channel Islands). Each landslide within the National Landslide Database is identified by a National Landslide Database ID number and a point location, as shown on this map. The National Landslide Database ID number represents an individual survey of a landslide, rather than just the landslide itself. This is because there could be several phases of movement within or extensions to the same landslide, particularly if it is a large and complex one. Subsequent surveys of the same landslide may be recorded in the database with the same National Landslide Database ID number but with a new Survey Number. Other information given for each record include; Landslide name, grid reference and whether the landslide record has been validated by the BGS Landslides Team. The point symbols at the designated location do not reflect the size and shape of the corresponding landslide, but just denote the recorded presence of a landslide within a range of accuracy.

    The BGS Debris Flow Susceptibility Model for Great Britain v6.1 is a 1:50 000 scale raster dataset of Great Britain providing 50 m ground resolution information on the potential of the ground, at a given location, to form a debris flow. It is based on a combination of geological, hydrogeological and geomorphological data inputs and is primarily concerned with potential ground stability related to natural (rather than man-made) geological conditions and slopes. The dataset is designed for those interested specifically in debris flow susceptibility at a regional or national planning scale such as those involved in construction or maintenance of infrastructure networks (road or rail or utilities), or other asset managers such as for property (including developers and home owners), loss adjusters, surveyors or local government. The dataset builds on research BGS has conducted over the past 15 years investigating debris flows. The model was designed to identify potential source-areas for debris flows rather than locate where material may be deposited following a long-run-out failure i.e. the track and flow of debris. This work focuses on natural geological and geomorphological controls that are likely to influence the initiation of debris flows. It therefore, does not consider the influence of land use or land cover factors.

    Fixed time lapse camera imagery with 15 minute interval during daytimes captured from Ben Donich (BNG: NN 2297 0637) looking towards the A83 Rest and Be Thankful / slope of Beinn Luibhean. Data were subsequently processed in https://doi.org/10.3390/rs13050893 for deformation tracking. There are data gaps during poor weather/outages, and, some camera shift requiring alignment.

    This is a point (.txt) file of 12,838 Asia Summer Monsoon (ASM) - triggered landslides that occurred across central-eastern Nepal in the period 1988 - 2018. This inventory includes the landslide locations (x, y coordinates of landslide crests) and geometries, as well as the following landslide attributes, where each attribute was extracted at the position of the landslide crest: elevation (m), slope (o), aspect (o), planform and profile curvature, excess topography (m3), local relief (m), distance to channel (m), distance to road (m), near channel ksn, near channel specific stream power (SSP), average 30-year precipitation, total annual rainfall, peak monthly rainfall, landuse, Permafrost index, geology, and tectonic unit. Note, landslides were not mapped in the years 2011 and 2012 due to scan line errors in the Landsat 7 imagery. These landslides and associated attributes were collected for the purpose of assessing how landslide spatial distributions and susceptibility vary through time.

    This is a polygon .shp file of 12,838 Asia Summer Monsoon (ASM) - triggered landslides that occurred across a ~45,000 km2 region of central-eastern Nepal in the period 1988 - 2018. This inventory includes the landslide locations, perimeters (Length field), areas and pre-/post- monsoon season satellite image dates used to map each landslide. Note, landslides were not mapped in the years 2011 and 2012 due to scan line errors in Landsat 7 imagery. These landslides were mapped for a range of purposes, from conducting landslide susceptibility assessments, to investigating landslide processes and preconditioning.
