A Geospatial Review Analysis of Increased Frequency of Large Glacier-Related Landslides in Mountainous Regions

As the world warms, many glaciers throughout the world are melting. Glacier melting has been linked to climate change as a major cause of landslides in mountainous regions. The whole effect of glacier growth and sublimation on landslide-induced denudation cannot be understood from an evaluation of the triggering mechanism alone. The proposed chapter constructed landslide and glacial statistics to represent the HMA employing a Landsat time-series spanning the last years to evaluate recent tendencies. Large earthquake-related landslides were isolated and deleted from the database, leaving a resource for investigating potential climate-change-related shifts. Mountainous locations are particularly susceptible to the impacts of climate change. The intricate web of connections among climatic, ecological, and sociocultural systems in these areas is being modified by the shifting climate. This chapter aims to investigate the forthcoming obstacles that these distinctive locations will face. Analysis using satellite images and landslide inventories indicates a substantial increase in the frequency of significant landslides associated with glaciers throughout recent decades. Our investigation is based on the research conducted in 2021 on the High Mountain Asia (HMA) region revealed that the extent of land impacted by landslides almost quadrupled during the time periods of 1999–2008 and 2009–2018. Additionally, the frequency of big landslides (>1 km2) also saw an increase throughout this timeframe. Present chapter examine the significance of these factors and identify the challenges that arise in the current environment and political landscape. The expansion of landslides is linked to the shrinking of glaciers. Proposed work based on the secondary sources of data, given dataset is very useful for risk assessment, is an inventory of landslides connected to glaciers.
