26.10. Influence of Soil Type on Wave Propagation

Try these first

1. 1.

   What is the main impact of soft soils on seismic waves?

   Hint

   Think about the characteristics of soft soils.

2. 2.

   What does liquefaction mean?

   Hint

   Consider the state of the soil when shaken.

3. 3.

   What is the effect of soft soils on S-waves and Rayleigh waves?

   • Amplifies the waves
   • Dampens the waves
   • No effect

   Hint

   Consider how soft soils behave under stress.

4. 4.

   True or False: Hard soils amplify seismic waves more than soft soils.

   • True
   • False

   Hint

   Reflect on the properties of both soil types.

5. 5.

   Discuss the long-term implications of liquefaction on urban development in areas with loose sands.

   Hint

   Consider the risks of flooding and ground instability.

6. 6.

   Analyze a hypothetical scenario where a major earthquake strikes a city with a layered soil profile. What effects would be expected on structures?

   Hint

   Think about how stress is distributed in the ground.
