Description

Surges are among the main sources of glacier hazards and complete surge-type glacier inventories are required for assessing glacier-related hazards. Glacier surge events in High Mountain Asia (HMA) are widely reported. Through the estimated elevation changes from multiple DEMs sources that acquired since 1970s (KH-9), here we present a new surge-type glacier inventory across HMA. The inventory has incorporated 1015 surge-type glaciers during the last four decades (1970s-2010s) with assigned indicators of surge possibility. Compared to previous surge-type glacier inventory in HMA, our inventory is theoretically more complete with the much longer observation period. The inventory is stored in the format of GeoPackage (*.gpkg) and ESRI Shapefile format (*.zip), which has integrated the geometric attributes (from RGI6.0) of each glacier. Detailed description including the attributes information can be found in the associate metadata file.
