Question 1.
What does PGA stand for?
Show hintHide hint
Think about it in the context of earthquakes!
Question 2.
In which units is PGA typically measured?
Show hintHide hint
What is acceleration due to gravity?
3Question 3.
What is the formula for calculating Peak Ground Acceleration?
- PGA = a(t)
- PGA = max |a(t)|
- PGA = min |a(t)|
Show hintHide hint
Look at the definition we discussed in class.
4Question 4.
Is PGA measured in units of g?
- True
- False
Show hintHide hint
Recall how we measure acceleration in physics.
Question 5.
During an earthquake, a recorded ground acceleration peaked at 12 m/s². Calculate the PGA in g.
Show hintHide hint
Remember the conversion of m/s² to g.
Question 6.
Discuss how the choice of location affects PGA measurements for two different sites: one in an urban area with soft soil and one on a rocky hillside. What might the differences in PGA be?
Show hintHide hint
Think about how materials impact earthquake forces.
