Answer 2

Answer:

Ans.1: The epicenter is the point on the Earth's surface directly above the focus. ... Figure 18.3: When the two blocks on either side of a fault plane suddenly slip, the energy travels outward from the focus as intense vibrations called seismic waves. These waves cause the ground near the epicenter to shake violently.

Ans.2: The 2001 Gujarat earthquake was caused by movement on a previously unknown south-dipping fault, trending parallel to the inferred rift structures.
