Question 1.
What is the role of seismic stations in epicentre determination?
Show hintHide hint
Think about why more data points enhance accuracy.
Question 2.
How does the magnitude of an earthquake affect its detection?
Show hintHide hint
Consider what happens during significant seismic events.
3Question 3.
What factor most significantly improves the accuracy of epicentre location?
- Increased seismic station density
- Earthquake depth
- Magnitude of the earthquake
Show hintHide hint
Consider how having multiple data points can assist in pinpointing a location.
4Question 4.
True or False: Deeper earthquakes are easier to locate accurately than shallow earthquakes.
- True
- False
Show hintHide hint
Think about the energy and travel distance of waves.
Question 5.
Analyze a scenario where a seismic network is very sparse. What challenges would arise in determining an epicentre, and how could you mitigate these issues?
Show hintHide hint
Consider how adding information changes data analysis.
Question 6.
Consider an earthquake that is deep-focus and of moderate magnitude. Discuss the approaches you would take to locate the epicentre accurately.
Show hintHide hint
Reflect on how depth might influence the propagation of seismic waves.
