Abstract:

Avalanche, Cloudburst, Flash Flood, and Glacial Lake Outburst Flood (GLOF) have recently increased in hilly regions due to Climate Change. This hazard damaged human life, wealth and also animal life. The main objective of the research study is to identify the impact of climate change on glaciers and assess the avalanche potential zone surrounding the Amarnath. The physical (climate data, terrain) and cultural configuration of the said region are coined from secondary sources i.e., the University of East Angelia climatic research unit, census reports, NASA, Geological Survey of India, Food and Agricultural Organisation and other raw maps downloaded from USGS i.e., mapped have lay outed by ArcGIS 10.2.2, QGIS 3.6.2 and Erdas Imagine 14 software. The shapefile of the boundary of glaciers and glacial lakes has been depicted by Global Land Ice Measurements from Space (GLIMS). Vegetation cover and snow cover are measured through Normalised Difference Vegetation Index (NDVI) and Normalised Difference Snow Index (NDSI), respectively. On 8th July 2022, a flash flood happened in the Amarnath cave area. 16 people died, 40 people were missing, 6 people were injured, and some base camps were washed out. The occurrence of global warming is the main cause, and human activities influence the cause of climate change.
