Challenge Problems
Push your limits with challenges.
Question 1
Suppose an earthquake of magnitude 7.2 reports a PGA of 0.45g at a nearby location. What might happen to the PGA if the magnitude increases to 8.2, considering attenuation effects?
💡 Hint: In nonlinear relationships, expect slow growth after a certain point.
Question 2
Discuss how engineers utilize seismic code factors to determine safety measures for buildings located on soft soil in a region prone to high-magnitude earthquakes.
💡 Hint: Think critically about inputs to design codes and regional challenges faced.
