Challenge Problems
Push your limits with challenges.
Question 1
Given a travel-time curve indicates that P-waves travel at 5 km/s, and a station recorded arrival in 15 seconds, determine the distance from the epicenter.
💡 Hint: Use the formula to find the distance.
Question 2
An earthquake's epicenter is located 10 km away. If the S-wave arrival time is 20 seconds, estimate using a travel-time curve that shows S-waves move at 3 km/s whether this is reasonable.
💡 Hint: Compare different velocities of waves.
