India has a very high frequency of great earthquakes. What could be the geological reasons / reasons for this?
1. India is currently penetrating in Asia
2. India is rotating clockwise
3. The molten magma under the earth’s crust beneath India is under enormous pressure
Choose the correct option from the codes given below:
The reasons of high magnitude earthquakes in India are hidden in the tectonic setting of India. India is currently penetrating into Asia at a rate of approximately 45 mm/year and rotating slowly anticlockwise. This rotation and translation results in left-lateral transform slip in Baluchistan at approximately 42 mm/year and right-lateral slip relative to Asia in the Indo-Burman ranges at 55 mm/year. At the same time, deformation within Asia reduces India’s convergence with Tibet to approximately 18 mm/year. Since Tibet is extending east-west, there Is a convergence across the Himalaya
that results in the development of potential slip available to drive large thrust earthquakes beneath the Himalaya at roughly 1.8 m/century.
