Challenge Problems
Push your limits with advanced challenges
Given an earthquake with a magnitude of 7.2 and a PGA of 0.7g, predict the liquefaction potential in a loose, saturated soil area and justify your reasoning.
💡 Hint: Analyze the effects of both magnitude and acceleration on liquefaction.
If an area experiences five strong motion cycles during an earthquake, with a magnitude of 6.0, evaluate the risk of liquefaction. What factors would contribute to this evaluation?
💡 Hint: Consider how cycle numbers in relation to other variables can influence liquefaction risk.
