Summary

Despite global efforts to compile landslide inventories annually, few attempts have been made to critically compare them using diverse techniques or investigators. Event-based inventories identify landslides from single events like earthquakes or rainstorms, aiding susceptibility mapping, hazard modeling, and risk management. After Nepal's Gorkha earthquake, researchers globally mapped induced landslides. This study qualitatively and quantitatively compares four published inventories using cartographical matching and frequency area distribution. The impact of satellite imagery resolution on inventory accuracy is also assessed. Findings highlight methodology choices, remote sensing techniques, and their limitations for effective landslide inventorying.
