Cryospheric hazards - in this case, thaw slumps (TS) and thermo-erosion gullies (TEG) - are phenomena typical of permafrost-dominated landscapes. Open datasets informing about their spatial, temporal and size distributions in the Arctic are still uncommon, as opposed to the systematic availability of this information for geomorphic processes in mid- to low- latitudes. To date, only the most populated region of Svalbard was covered with TS and TEG inventories. Here, we extend the respective information to most of the Archipelago, totalling 8491 polygons, out of which 3679 are TSs and 4812 are TEGs. These have been manually mapped from aerial photographs throughout Svalbard across the 14 largest ice-free regions. The SvalCryo inventory is highly relevant as the Arctic environment undergoes alarming changes in response to global warming. The idea behind the two inventories is to support the geoscientific community in the quest to evaluate the environmental response to climate change, by creating a baseline for change monitoring, and ultimately to serve as basis for susceptibility, hazard and risk assessment models.

Over 169 people along the Simangulampe upstream were under devastating flood and worst landslide watches in December 2023 due to a significant storm bringing the heaviest rainfall and moving giant boulders. Indeed, there are far fewer studies and information on susceptibility hazards in Simangalumpe than in others. First-rate information on impressive risk mitigation strategies increased climate-change consideration and reduced flood risk. We adopt C-band synthetic aperture radar and multispectral imagery from Sentinel to identify, visualize, and analyze flash flood mapping and mitigating to address this issue. Precisely, Simangalumpe flood is considered from surface water indices with various parameters: Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), Modified NDWI (MNDWI), and SAR flood inundation mapping. Results show low NDVI values- over 50 percent of plant canopies are damaged (uprooted and broken trees) along Simangulampe upstream. Combining multispectral and SAR properties of the surface water index shows the surface extent of water bodies in Simagalumpe upstream and covers giant boulders. Finally, developing spatial and temporal analysis from multispectral and SAR data results in information on mitigating flash flooding and reducing unnecessary threats.
