Challenge Problems
Push your limits with advanced challenges
Using the following GMPE coefficients: a=0.1, b=0.3, c=0.7, d=1.0, calculate the PGA for a magnitude 7.0 earthquake located 20 km from the site. Consider the importance of site conditions in adjusting your answer.
💡 Hint: Apply the base logarithmic equation stepwise.
Given two GMPEs, one for subduction zones and another for intraplate regions, compare and discuss how PGA predictions might differ based on tectonic settings. Use examples from real earthquakes.
💡 Hint: Look into the features of past earthquakes in both regions.
