19.16. Seismic Hazard Assessment

Try these first

1. 1.

   What does DSHA stand for and what is its focus?

   Hint

   Remember, it relates to maximum expected shaking.

2. 2.

   List one output from the DSHA approach.

   Hint

   Think about what helps engineers design buildings.

3. 3.

   What does PSHA consider that DSHA does not?

   • Only the largest earthquake
   • Variability of earthquakes
   • Fixed ground shaking levels

   Hint

   Think about the nature of risk in hazards.

4. 4.

   True or False: Hazard curves represent fixed and static ground shaking levels.

   • True
   • False

   Hint

   Recall how hazard curves convey dynamic information.

5. 5.

   Create a seismic hazard assessment report for a hypothetical city prone to earthquakes. Include both DSHA and PSHA results and the implications for urban planning.

   Hint

   Incorporate factual historical data to strengthen your argument.

6. 6.

   Explain how changing the parameters in PSHA affects the risk contours and output. Provide a detailed example.

   Hint

   Use statistical models to back your explanation.
