35.10. Site-Specific Peak Acceleration Estimation

Try these first

1. 1.

   What does PGA stand for?

   Hint

   Think about ground movement during an earthquake.

2. 2.

   What is the purpose of GMPEs?

   Hint

   Consider the role of mathematics in predicting earthquakes.

3. 3.

   What does PGA estimate?

   • Peak Ground Acceleration
   • Peak Ground Area
   • Peak Ground Analysis

   Hint

   Think about what 'PGA' might represent in the context of earthquakes.

4. 4.

   Is it true that soft soils can amplify ground motion?

   • True
   • False

   Hint

   Consider how different soil types behave during shaking.

5. 5.

   Suppose you are tasked with estimating PGA for a new building site near a known fault line. Identify the steps you would take and justify your choices.

   Hint

   Think about each stage and how they interconnect.

6. 6.

   If you discovered that a construction authority used only a deterministic model for planning a site near unstable soils, what issues might arise?

   Hint

   Consider the limitations of deterministic models.
