Q2. What are the key climatic and geomorphological factors contributing to avalanche formation in the Indian Himalayas? How do they differ from those in mid-latitude mountain systems? (10 M)
Difficulty Level: Medium
Reference: IE
Why the question: Avalanches are no longer seasonal inconveniences. They demand urgent attention. Key demand of the question: The question requires an understanding of both climatic and geomorphological triggers specific to the Indian Himalayas and a comparison with mid-latitude avalanche systems to highlight spatial and process-based contrasts. Structure of the Answer: Introduction Briefly define avalanche and highlight its increasing relevance in Indian high-altitude terrain under climate stress. Body Point on unique climatic triggers such as temperature fluctuation, rain-on-snow events, and monsoonal disturbances. Point on geomorphological characteristics like tectonic instability, slope gradient, and glacial debris presence. How these features differ from those in Alps or Rockies in terms of snow quality, predictability, altitude, and anthropogenic pressure. Conclusion Suggest that India must adopt a terrain-responsive disaster mitigation strategy, backed by geospatial and climate forecasting integration.
