Challenge Problems
Push your limits with advanced challenges
Consider an earthquake where P-waves arrive at three stations A, B, and C at times t1, t2, and t3 seconds respectively. If the speed of P-waves is known to be 5 km/s, derive the possible locations of the epicentre based on these arrival times.
💡 Hint: Draw a diagram to visualize the situation.
An area experiences a significant earthquake, and you have recordings from various seismic stations. Evaluate how you would utilize both triangulation and moment tensor inversion in your analyses.
💡 Hint: Think sequentially: which method provides initial data and which refines it?
