Challenge Problems

Push your limits with challenges.

Question 1

A seismic event occurs, and data is collected from a well-distributed network of 10 seismic stations versus a sparse network of 3 stations. Discuss how the difference in data collection will affect the error ellipses and the confidence in the epicenter determination.

💡 Hint: Consider how data quantity can enhance precision.

Question 2

How might geological structures like mountains and valleys affect seismic wave paths, leading to changes in error ellipse sizes? Provide examples.

💡 Hint: Think about how obstacles might alter wave behavior.
