20.13.2. Wave Propagation and Attenuation

Try these first

1. 1.

   What is attenuation in the context of seismic waves?

   Hint

   Think about what happens to sound as you move away from the source.

2. 2.

   Name one factor that affects wave speed.

   Hint

   Consider the different types of ground we see around our neighborhoods.

3. 3.

   What is the term for the decrease in intensity of seismic waves as they propagate?

   • Amplification
   • Attenuation
   • Refracted Waves

   Hint

   Think about how sound fades with distance.

4. 4.

   True or False: Seismic waves travel faster through soft soils than through solid rocks.

   • True
   • False

   Hint

   Consider the resistance offered by different materials.

5. 5.

   Given a scenario where a seismic wave moves from granite to clay, explain how the behavior of the wave changes.

   Hint

   Visualize how a ball bounces differently on grass compared to a concrete surface.

6. 6.

   Discuss how building engineers can utilize knowledge of wave propagation and attenuation to design buildings in earthquake-prone areas.

   Hint

   Think about how different materials behave under stress during an earthquake.
