Question 1.
What is epicentral distance?
Show hintHide hint
Think about the epicenter's location.
Question 2.
How does distance from an earthquake impact PGA?
Show hintHide hint
Consider seismic wave energy as it travels.
3Question 3.
What is the effect of increasing epicentral distance on PGA?
- Increases
- Decreases
- Remains the same
Show hintHide hint
Remember the concept of wave energy loss.
4Question 4.
True or False: GMPEs are used to predict how PGA varies with distance.
- True
- False
Show hintHide hint
Consider why we need formulas in seismic engineering.
Question 5.
Calculate the approximate PGA at a site 25 km from a 7.0 magnitude earthquake using a GMPE that indicates a PGA of 0.5g at 10 km.
Show hintHide hint
Reference GMPE charts or attenuation equations for specific calculations.
Question 6.
Discuss the engineering implications of utilizing a GMPE with limited data based on regional seismic activity.
Show hintHide hint
Think critically about the consequences of uncertainty in data.
