Challenge Problems
Push your limits with challenges.
Question 1
If two seismic stations recorded P-wave and S-wave arrival times of 2s and 6s, and 3s and 9s respectively, discuss how you would apply the triangulation method. What discrepancies would you expect due to distance?
💡 Hint: Consider the role of distance and placement when using waves' arrival times.
Question 2
Imagine you are a seismologist. Given a seismic station is 50 km away from the epicentre and recorded P-wave arrival time as 5 seconds, calculate the expected S-wave arrival time, given S-waves travel at 60% the speed of P-waves which travel at approximately 8 km/s.
💡 Hint: Use the formula for time = distance / speed and remember the relationship between P-waves and S-waves.
