Question 1.
What happens to earthquake intensity as the distance from the epicenter increases?
Show hintHide hint
Think about how sound dissipates over distance.
Question 2.
Name one factor that might increase earthquake shaking intensity.
Show hintHide hint
Consider what types of ground would absorb or amplify vibrations.
3Question 3.
What is the effect of increasing distance from the epicenter on earthquake intensity?
- It increases intensity
- It decreases intensity
- It has no effect
Show hintHide hint
Consider how sound and energy behave over distance.
4Question 4.
True or False? Soft soil can amplify the effects of an earthquake.
- True
- False
Show hintHide hint
Think about how different surfaces interact with earthquake waves.
Question 5.
Analyze an earthquake with a magnitude of 7.0 occurring 10 km from a city built on soft soil and compare the predicted intensity with that of a similar earthquake occurring 70 km away from a city on hard rock.
Show hintHide hint
Consider how different soil types and distances work together to impact observed intensity.
Question 6.
Discuss how emergency planners should consider both distance from the epicenter and local conditions when assessing earthquake risk in urban areas.
Show hintHide hint
Remember this combines both the physical distance and the nuances of local geology.
