Challenge Problems
Push your limits with challenges.
Question 1
Given a travel-time curve, if a P-wave arrives after 6 seconds and an S-wave arrives after 10 seconds, calculate the approximate distance to the epicenter if the wave speeds are 6 km/s for P-waves and 3.5 km/s for S-waves.
💡 Hint: Ensure you are using the right formula, which involves distance equal to speed times time.
Question 2
Explain why understanding travel-time curves is vital in emergency response following an earthquake.
💡 Hint: Think about the immediate needs after an earthquake.
