The areas and volumes of 12,920 Asia Summer Monsoon (ASM) triggered landslides in Nepal. (NERC Grant NE/L002582/1)
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.
Landslides were mapped manually through visual interpretation of pre- and post-monsoon season Landsat 4/5/7/8 images, the dates of which are included within the text file. Scar areas were estimated using the methods of Marc & Hovius (2015) and Marc et al. (2018) (which estimate scar areas based on landslide widths), whilst volumes were calculated using the scaling relationships of Larsen et al. (2010). Note, landslides were not mapped in the years 2011 and 2012 due to scan line errors in the Landsat 7 imagery.ing the methods of Marc & Hovius (2015) and Marc et al. (2018), whilst volumes were calculated using the scaling relationships of Larsen et al., (2010).
