Question 1.
What does PGA stand for?
Show hintHide hint
Think of what it measures in terms of ground movement.
Question 2.
Does a higher earthquake magnitude always mean a higher PGA?
Show hintHide hint
Consider how the increase rate changes.
3Question 3.
What is Peak Ground Acceleration primarily used for?
- To measure temperature
- To inform seismic design
- To assess wind speed
Show hintHide hint
Consider what happens during an earthquake.
4Question 4.
True or False: The increase in PGA continues to be proportional with increasing earthquake magnitude indefinitely.
- True
- False
Show hintHide hint
Think about how energy behaves as it grows.
Question 5.
Suppose an earthquake of magnitude 7.2 reports a PGA of 0.45g at a nearby location. What might happen to the PGA if the magnitude increases to 8.2, considering attenuation effects?
Show hintHide hint
In nonlinear relationships, expect slow growth after a certain point.
Question 6.
Discuss how engineers utilize seismic code factors to determine safety measures for buildings located on soft soil in a region prone to high-magnitude earthquakes.
Show hintHide hint
Think critically about inputs to design codes and regional challenges faced.
