2. Option C is correct.

  • Statement 1 is correct Volcanic vents are generally far away from the epicenters of most major shallow earthquakes.
  • Statement 2 is not correct Primary waves are longitudinal while secondary waves are transverse waves.
  • Statement 3 is correct The more elastic the material is, the higher is the velocity of surface waves.

 

3. Option C is correct.

  • Statement 1 is not correct “Pacific ring of fire” accounts for about 68 per cent of all earthquakes.
