General Science (DRDO) (Phase-I and II) Physics

Which of the following earthquake waves are more destructive at the epicentre?

S - waves

P - waves

R - waves

L - waves

- P-waves (Option 2):

- Also known as primary or compressional waves.

- First waves to arrive during an earthquake.

- Travel through solids, liquids, and gases.

- Generally the least destructive.

- S-waves (Option 1):

- Also known as secondary or shear waves.

- Arrive after P-waves.

- Can only move through solids.

- More destructive than P-waves but less than surface waves.

- R-waves (Option 3):

- Also known as Rayleigh waves.

- Surface waves that roll along the ground.

- Can be highly destructive due to their rolling movement.

- L-waves (Option 4):

- Also known as Love waves.

- Surface waves that cause horizontal shearing.

- Typically the most destructive at the epicenter due to their high amplitude and horizontal shearing motion.

L-waves (Option 4) seems correct:
