24.2.1. Ground Shaking Intensity

Try these first

1. 1.

   What is the epicentre of an earthquake?

   Hint

   Think about where the earthquake originates.

2. 2.

   Name one factor that influences ground shaking intensity.

   Hint

   Consider what the earthquake waves travel through.

3. 3.

   Where does maximum ground motion occur during an earthquake?

   • Near the surface
   • At the epicentre
   • At the hypocentre

   Hint

   Think about where the earthquake originates.

4. 4.

   True or False: Ground shaking intensity increases with distance from the epicentre.

   • True
   • False

   Hint

   Remember how seismic waves lose energy.

5. 5.

   Design a building in a highly seismic zone considering ground shaking intensity. What materials and design features would you select to mitigate potential damage?

   Hint

   Consider how materials interact with seismic forces.

6. 6.

   Analyze the effects of a shallow versus deep earthquake in an urban area. How would you assess potential building impacts?

   Hint

   Think about the mechanical wave behavior in different layers of the Earth.
