27.6.2. Peak Ground Velocity (PGV)

Try these first

1. 1.

   What does PGV stand for?

   Hint

   Think of the first letters of each word.

2. 2.

   What instrument measures PGV?

   Hint

   This instrument is used during earthquakes.

3. 3.

   What does PGV measure during an earthquake?

   • Ground acceleration
   • Ground displacement
   • Ground velocity

   Hint

   Think about what 'velocity' refers to.

4. 4.

   True or False: PGV can help predict structural damage in buildings.

   • True
   • False

   Hint

   Recall why engineers look at PGV.

5. 5.

   Given a map showing varying PGV levels across a city, outline the recommended building practices for each area based on PGV. Include which areas would need stricter codes.

   Hint

   Use the PGV data to assess risk levels.

6. 6.

   How would you argue the importance of integrating PGV assessments into urban planning policies for a city prone to earthquakes?

   Hint

   Think about safety, risk management, and planning for the future.
