24.2. Geophysical and Geological Importance of the Epicentre

Try these first

1. 1.

   Where does maximum ground shaking occur during an earthquake?

   Hint

   Think about where the earthquake's energy originates.

2. 2.

   True or False: The intensity of shaking increases as you move away from the epicentre.

   Hint

   Remember that energy diminishes with distance.

3. 3.

   Where is the maximum ground shaking experienced during an earthquake?

   • At the epicentre
   • At the hypocentre
   • At a distance from the epicentre

   Hint

   Think about where the earthquake starts.

4. 4.

   True or False: Geological damping affects how seismic waves are transmitted through the Earth.

   • True
   • False

   Hint

   Consider the materials that can absorb seismic energy.

5. 5.

   In a hypothetical earthquake scenario, if an epicentre is located at a depth of 10 km and a building 2 km away sustains 50% damage, discuss how depth and distance may have influenced this damage compared to a building 20 km away.

   Hint

   Consider the concept of intensity decay with distance.

6. 6.

   Design a disaster response plan utilizing the concept of epicentre location. Include considerations for building regulations in high-risk zones based on soil types and fault lines.

   Hint

   Think about how proximity to faults impacts infrastructure resilience.
