Question 1.
What is a seismic gap?
Show hintHide hint
Think about the stress buildup along faults.
Question 2.
Give one example of an earthquake precursor.
Show hintHide hint
These often occur smaller before a larger quake.
3Question 3.
What is a seismic gap?
- A section of a fault that has moved recently
- A section of a fault that hasn't moved for a while
- An area with no faults
Show hintHide hint
Think about pressure buildup over time.
4Question 4.
True or False: Foreshocks can help predict larger earthquakes.
- True
- False
Show hintHide hint
Recall if foreshocks usually precede significant seismic events.
Question 5.
Given a scenario where a seismic gap exists in a densely populated area, describe how city planners should address this risk in their infrastructure development.
Show hintHide hint
Consider what engineering measures could best mitigate risks.
Question 6.
Analyze the limitations of using only one type of precursor for predicting earthquakes, such as only focusing on foreshocks.
Show hintHide hint
Think about the variability of natural phenomena and the need for comprehensive data.
