Answer 1

India is mainly divided into 4 seismic zones. These are Zone 2, Zone 3, Zone 4, and Zone 5. Delhi lies in the very sensitive Seismic Zone 4. Other regions which lie in Zone 4 are Indo-Gangetic basin, Jammu and Kashmir, and Koyna region of Maharashtra. Areas under Zone 5 include western and central Himalayas, Rann of Kutch, and North-East India, and are even more vulnerable to massive earthquakes.

Answer 2

Answer:

In the list of 5 most earthquake prone cities in India, Delhi owns the third spot. Zoning is done on the basis of the number of active fault lines on the earth's surface which may or may not become the epicenter of an earthquake. A fault line is similar to a joint or a junction.
