Question 1
What is the effect of distance on earthquake ground motion?
- Increases motion
- Decreases motion
- Has no effect
💡 Hint: Remember how the energy dissipates over distance.
Question 2
True or False: PGA is a measure of energy released at the earthquake's source.
- True
- False
💡 Hint: Focus on what PGA specifically refers to in terms of measurement.

Challenge Problems
Push your limits with challenges.
Question 1
A 7.0 magnitude earthquake occurs at a distance of 30 km from a city. Using the appropriate ground motion prediction equations, estimate the expected PGA, considering site conditions of soft soil.
💡 Hint: Remember to account for the effects of soil type in your calculations.
Question 2
Discuss how variations in local geology can create differing levels of expected ground shaking in earthquake-prone areas, and how engineers can adjust designs accordingly.
💡 Hint: Reflect on the relationship between geology and seismic energy propagation.
