20.20. Influence of Geological and Geomorphological Features

Try these first

1. 1.

   What is soil amplification?

   Hint

   Think about how a trampoline might move when someone jumps on it.

2. 2.

   How do hills affect seismic waves?

   Hint

   Consider why a magnifying glass focuses light.

3. 3.

   What is the effect of soil amplification during an earthquake?

   • It reduces shaking
   • It increases shaking
   • It has no effect

   Hint

   Think about how a trampoline bounces someone higher.

4. 4.

   True or False: Liquefaction can cause buildings to sink during an earthquake.

   • True
   • False

   Hint

   Imagine a wet sponge versus a solid one.

5. 5.

   Analyze a case study of a recent earthquake. Compare the seismic effects in urban areas with soft soil to those on solid ground.

   Hint

   Use historical data from the quake.

6. 6.

   Design a public awareness campaign centered around liquefaction risk in coastal cities. What key messages would you include?

   Hint

   Focus on community engagement and practical examples.
