Q2. Explain the tectonic processes responsible for frequent earthquakes in the Himalayan region. How do these earthquakes impact the hydrology and ecology of the region? (10 M)
Difficulty Level: Easy
Reference: TH
Why the question An earthquake with a magnitude of 7.1 struck Tibetan China and Nepal. The epicentre was located 10 km below a spot around 80 km north of Mt Everest. Key demand of the question The answer should explain the tectonic processes causing frequent earthquakes in the Himalayan region and evaluate their impact on water resources, glaciers, and ecosystems. Structure of the Answer Introduction Start with the significance of the Himalayas as a tectonic collision zone and its seismic vulnerability. Add a recent example of a major earthquake to set the context. Body Tectonic processes responsible for earthquakes: Briefly discuss plate tectonics, fault systems, and the stress accumulation causing seismic activity. Impact on hydrology: Mention changes in river systems, risks to water infrastructure, and glacial dynamics. Impact on ecology: Highlight disruptions to ecosystems, biodiversity loss, and increased disaster risks like landslides. Conclusion Provide a forward-looking statement emphasizing sustainable development, disaster preparedness, and resilient infrastructure in earthquake-prone regions. Why the question
