Step-by-step explanation:
Seismic waves can be categorized into two main groups;
Body waves and Surface waves
Body waves are propagated through a material
Surface waves moves through the surface
Primary waves:
- They are called P-waves or primary waves
- These waves have the fastest velocity of all types of seismic waves - 5 to 8km/s
- They can pass through any materials because they are longitudinal waves.
- They are also called compressional waves
Secondary waves:
- These are s-waves or shear waves and are body waves
- They have a velocity of about 1-5km/s
- These waves are transverse waves
- They cannot pass through a region made up of fluids
Love waves
- They are transverse waves
- These waves are surface waves
- They move horizontally on the surface
- Love waves cannot pass through liquids
Rayleigh waves
- They are surface waves
- They have both horizontal and vertical motion
- They can pass through both liquids and solids.
