24.12.2. Impact on Ground Motion

Try these first

1. 1.

   What defines a shallow-focus earthquake?

   Hint

   Think about how deep they are.

2. 2.

   What type of waves are produced by deep-focus earthquakes?

   Hint

   Consider what happens to energy as it travels deeper.

3. 3.

   What is the depth range of shallow-focus earthquakes?

   • 0-70 km
   • 70-300 km
   • 300-700 km

   Hint

   Think about the first range above the surface.

4. 4.

   True or False: Intermediate-focus earthquakes cause sharper shaking than shallow-focus earthquakes.

   • True
   • False

   Hint

   Remember how depth affects wave energy.

5. 5.

   Discuss the implications of developing urban areas in regions prone to shallow-focus earthquakes. What measures should be taken?

   Hint

   Consider how different depths affect planning.

6. 6.

   Analyze how varied geological materials in an area could influence the impact of multi-depth earthquakes.

   Hint

   Think about how ground conditions alter quake responses.
