3 cards from this section. Quick, good the night before a test.
What does PGA stand for?
This term measures the intensity of shaking during an earthquake.
List one factor that increases liquefaction potential.
Think about what happens during a stronger earthquake.
What does a higher earthquake magnitude generally indicate for liquefaction?
Consider the relationship between energy and seismic activity.
True or False: Peak Ground Acceleration (PGA) is irrelevant to liquefaction risk.
Think about what PGA specifically measures.
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.
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?
Consider how cycle numbers in relation to other variables can influence liquefaction risk.
