25.13. Hypocentre vs Epicentre: Engineering Implications

Try these first

1. 1.

   Define hypocentre in your own words.

   Hint

   Think about where an earthquake starts.

2. 2.

   What is the epicentre?

   Hint

   It's what you see on a map representing the earthquake's surface effect.

3. 3.

   What is the primary function of the hypocentre in earthquake evaluation?

   • To map hazard zones
   • To indicate wave propagation
   • To provide surface location

   Hint

   Remember the wave path discussions.

4. 4.

   True or False: The epicentre is located below the Earth's surface.

   • True
   • False

   Hint

   Think about the location of each term.

5. 5.

   Given an earthquake occurs with a hypocentre depth of 25 km, predict its likely impact on buildings located 10 km from the epicentre.

   Hint

   Consider the effects of depth on wave energy and how it dissipates by the time it reaches the surface.

6. 6.

   Evaluate how building codes might differ if an area's seismic activity showed a trend of shallower hypocentres compared to deeper ones.

   Hint

   Think about how earthquake risks increase with depth and proximity.
