Topic: Important Geophysical phenomena such as earthquakes, Tsunami.
Q1. Describe the spatial distribution of earthquakes in the Indian subcontinent. Explain the role of tectonic boundaries. (10 M)
Difficulty Level: Easy
Reference: NIE
Why the question
Frequent earthquakes in the Himalayan region highlight the importance of understanding seismic patterns and tectonic processes.Key Demand of the question
The question requires explaining the regional pattern of earthquake occurrence across the Indian subcontinent and linking it with tectonic settings. It further demands explaining how different types of plate boundaries influence seismicity.Structure of the Answer:
Introduction
Briefly mention India’s location at the convergence of major tectonic plates and its seismic vulnerability.Body
- Spatial distribution of earthquakes: Indicate major seismic belts such as Himalayas, Northeast, peninsular and island regions.
- Role of tectonic boundaries: Explain how convergent, subduction and fault zones influence earthquake occurrence.
Conclusion
Provide a forward-looking line linking tectonic understanding with disaster preparedness and planning.
