27.3.2. Amplitude Analysis

Try these first

1. 1.

   What does PGA stand for?

   Hint

   Think about what it measures during an earthquake.

2. 2.

   Why is amplitude analysis important?

   Hint

   Consider the implications for engineering.

3. 3.

   What does PGA measure in seismology?

   • Maximum ground velocity
   • Maximum ground acceleration
   • Ground displacement

   Hint

   Remember, it's about how quickly the ground is shaking.

4. 4.

   True or False: A higher PGV indicates a greater potential for structural damage.

   • True
   • False

   Hint

   Think about how building stability is affected by ground motion speed.

5. 5.

   A building designed in a region with a PGA of 2.0 g needs to be assessed for earthquake resilience. What design considerations must be taken into account?

   Hint

   Reflect on how engineers would modify designs for increased safety.

6. 6.

   Discuss the implications of inaccurate measurement tools on the analysis of PGV and subsequently on construction safety.

   Hint

   Think about real-world impacts of technology in seismology.
