20.13. Seismic Waves and Their Propagation

Try these first

1. 1.

   What type of wave is faster, P-wave or S-wave?

   Hint

   Remember which wave comes first.

2. 2.

   Which waves can travel through liquids?

   Hint

   Think about the type of wave that is termed primary.

3. 3.

   Which type of seismic wave is faster?

   • P-wave
   • S-wave
   • Love Wave

   Hint

   It's the 'primary' wave!

4. 4.

   True or False: S-waves can travel through liquids.

   • True
   • False

   Hint

   Remember the types of materials each wave can traverse.

5. 5.

   Evaluate the potential effects of a major earthquake occurring near a city built on soft sedimentary foundations versus one built on solid rock.

   Hint

   Consider how seismic waves behave differently in various materials.

6. 6.

   Propose a design strategy for buildings in earthquake-prone areas that account for the properties of P-waves and S-waves.

   Hint

   Think about how waves interact with buildings and how to minimize damage.
