26.2.3. Velocity and Attenuation

Try these first

1. 1.

   What are S-waves and how do they move?

   Hint

   Think about how the wave moves compared to P-waves.

2. 2.

   Are S-waves faster or slower than P-waves?

   Hint

   Recall the order of wave speeds among seismic waves.

3. 3.

   Which wave travels faster than S-waves?

   • P-waves
   • Rayleigh Waves
   • Love Waves

   Hint

   Use the mnemonic 'P is for quick, S is in between, Rayleigh is last.'

4. 4.

   Attenuation in seismic waves refers to the:

   • True
   • False

   Hint

   Think about how wave energy diminishes as it travels.

5. 5.

   Given a geological formation with both hard and soft materials, predict how the presence of each will affect S-wave propagation and attenuation.

   Hint

   Think about how density and elasticity impact wave behavior.

6. 6.

   How might engineers adjust building designs to accommodate high attenuation rates of S-waves in a specific area prone to earthquakes?

   Hint

   Consider what adjustments would be necessary for areas with predicted high seismic activity.
