S-waves Flashcards
What type of seismic wave is also known as S-waves?
Secondary waves
True or False: Secondary waves are slower than primary waves.
True
What is the wave motion of secondary waves?
Shear motion
Which type of wave can only travel through solid materials?
Secondary waves
Do secondary waves cause more or less damage during an earthquake compared to primary waves?
More damage
What is the typical speed range of secondary waves?
Between 2-8 km/s
In which layer of the Earth do secondary waves travel faster, the outer core or the mantle?
Mantle
Secondary waves are responsible for creating what type of motion in buildings during an earthquake?
Swinging motion
What is the wavelength range of secondary waves?
0.1-0.5 times the wavelength of primary waves
How are secondary waves characterized in terms of amplitude compared to primary waves?
Smaller amplitude
What is the frequency range of secondary waves?
1-20 Hz
What type of material is most resistant to secondary wave propagation?
Solid material
What is the order of arrival of seismic waves during an earthquake, with secondary waves?
Primary waves, Secondary waves, Surface waves
What causes the ground to move side-to-side during an earthquake?
Secondary waves
What is the depth range at which secondary waves can travel?
Up to 700 km
Secondary waves are also known as what type of waves?
Shear waves
Which type of wave causes the most shaking during an earthquake, primary or secondary waves?
Secondary waves
What is the particle motion associated with secondary waves?
Perpendicular to wave direction
Do secondary waves travel through liquids?
No
What is the symbol used to represent secondary waves?
S
How does the amplitude of secondary waves change with distance from the earthquake source?
Decreases
