Challenge Problems
Push your limits with challenges.
Question 1
Given a magnitude 7.0 earthquake occurring at a depth of 10 km, use an attenuation model to estimate the PGA at a location 20 km away. Discuss your approach and calculations.
💡 Hint: Identify the constants for your specific model.
Question 2
Analyze how geological variances might lead to the cropping of peaks in different seismic regions when predicting PGA. Provide examples.
💡 Hint: Consider how waves might change in shape and intensity.
