27.9.1. Criteria for Selection

Try these first

1. 1.

   What is the significance of earthquake magnitude?

   Hint

   Think about how we assess earthquake impacts.

2. 2.

   Why is distance to the fault important for ground motion selection?

   Hint

   How does distance affect shaking?

3. 3.

   What factor indicates how powerful an earthquake is?

   • Distance to Fault
   • Magnitude
   • Soil Condition

   Hint

   It’s a numerical value reflecting strength.

4. 4.

   True or False: Soil conditions do not affect seismic waves.

   • True
   • False

   Hint

   Consider different soil types.

5. 5.

   Evaluate a fictional site with clay soil near a fault line after a 7.0 magnitude earthquake. Discuss the ground motion effects you would expect.

   Hint

   Think about how structures react in different soil types.

6. 6.

   A town faced an earthquake of 6.5 magnitude at a distance of 30 km. Another town experienced a 5.5 magnitude quake just 10 km away. Compare the expected ground motions.

   Hint

   Link magnitude and distance to analyze.
