Question 1.
What is wave trapping?
Show hintHide hint
Think about how waves behave in a canyon or a basin.
Question 2.
Describe what multiple reflections are.
Show hintHide hint
Consider what happens to sound in a closed room.
3Question 3.
What phenomenon occurs when Rayleigh waves get trapped in sedimentary basins?
- A) Shortened shaking
- B) Prolonged shaking
- C) No effect
Show hintHide hint
Think of a wave moving back and forth in a confined space.
4Question 4.
True or False: Multiple reflections can amplify shaking during an earthquake.
- True
- False
Show hintHide hint
Consider the concept of amplifying effects in acoustics.
Question 5.
Consider a region with a major sedimentary basin. Propose a design strategy for a high-rise building that would be effective in mitigating the effects of basin and valley interactions during an earthquake.
Show hintHide hint
Think about how to enhance stability against amplified motions.
Question 6.
Analyze how the presence of a nearby valley might affect the strategy for an emergency response plan after an earthquake. What additional considerations must be made?
Show hintHide hint
Consider geographical variations in accessibility and safety.
