Seismic Waves Flashcards
What can P waves travel through
Solids and liquids
How fast do P waves travel?
7-14km/s
Characteristic of P wave
Small amplitude, compressional and longitudinal (push-pull)
What can S waves travel through
Solids
How fast do S waves travel
60% speed of P’s
4-8km/s
Characteristics of S waves
Bigger amplitude, transverse (s-shape)
What can love waves travel through
Solids
What do Love waves do
Make buildings collapse with their shearing effect
Characteristic of Love wave motions
Side-side
How do Rayleigh waves move
In a rolling motion
What can Rayleigh waves travel through?
Liquids and solids
Which waves can travel through both liquids and solids
P and Rayleigh
Which waves can only travel through solids
S and Love
What happens at a chance in density?
Refraction (Gutenburg discontinuity)
