Which waves can travel slowly within the surface?

Which waves can make dramatic ground movements?

Which waves can compress and expand the ground like an accordion?

Which waves can travel through solids and can violently shake structures when they reach the surface?

Answer 1

1) Which waves can travel through both solids and liquids?
- P-waves (primary or compressional waves). They travel through solids, liquids and gases.

2) Which waves can travel slowly within the surface?
- Surface waves (Rayleigh and Love waves). They travel along the Earth's surface and are slower than body waves.

3) Which waves can make dramatic ground movements?
- Surface waves (especially Rayleigh waves for rolling vertical motion and Love waves for strong horizontal shear).

4) Which waves can compress and expand the ground like an accordion?
- P-waves (compressional, push–pull motion parallel to propagation).

5) Which waves can travel through solids and can violently shake structures when they reach the surface?
- S-waves (secondary or shear waves). They travel only through solids and produce strong sideways shaking that can damage buildings.
