Q2. Why is the Himalayan region considered a high-risk seismic zone? Examine the role of tectonic processes in shaping this vulnerability. Explain how demographic concentration and gaps in policy implementation exacerbate the threat. (15 M)
Difficulty Level: Easy
Reference: TH
Why the question: The recent tremors in Delhi and frequent earthquakes across the Himalayan arc underline the need to assess the region’s tectonic volatility, especially in the context of rapid urban expansion and policy inaction. Key Demand of the question: The question requires explaining the seismic sensitivity of the Himalayas due to geotectonic factors and critically examining how urban density and lack of effective policy implementation worsen this natural hazard. Structure of the Answer: Introduction: Mention the Himalayan region as a dynamic tectonic boundary with a long history of seismicity and increasing anthropogenic pressures. Body: Briefly explain how the Himalayan region’s geological youth and tectonic convergence make it prone to earthquakes. Point out the key tectonic processes—plate collision, active fault systems, and seismic gap accumulation—that contribute to frequent quakes. Examine how rapid population growth, unregulated urbanisation, and construction in hazard-prone areas increase vulnerability. Highlight the institutional weaknesses—poor enforcement of seismic codes, lack of retrofitting, and inadequate public preparedness—that magnify the disaster potential. Conclusion: Emphasise the urgency of region-specific seismic governance combining scientific monitoring, structural resilience, and public awareness to avert a future catastrophe.
