Question

1. which type of seismic wave (p - waves, s - waves or l - waves) produces the most severe ground movements and the most damage on the surface of the earth?

Explanation:

P - waves are compressional waves and are the fastest, but not the most damaging. S - waves are shear waves and are stronger than P - waves but still not the most destructive at the surface. L - waves (Love and Rayleigh waves) are surface waves. They move slower than body waves (P and S - waves) but cause the most severe ground movements and damage at the surface as they have larger amplitudes and more complex motion patterns.

Answer:

L - waves
