25.15.2. 3D Fault Imaging

Try these first

1. 1.

   What is a hypocentre?

   Hint

   Think about where the earthquake begins.

2. 2.

   Why is fault dip important?

   Hint

   Consider how angles might impact rupture.

3. 3.

   What is the primary function of hypocentre data in earthquake studies?

   • Predicting weather patterns
   • Understanding seismic behavior
   • Mapping ocean currents

   Hint

   Consider what happens when an earthquake begins.

4. 4.

   True or False: Subsurface fracture systems have no effect on seismic wave propagation.

   • True
   • False

   Hint

   Think about different paths for the waves.

5. 5.

   Consider an area with many visible surface fractures and a known fault line. How would you evaluate the potential seismic risks based on hypocentre mapping?

   Hint

   Look into the interaction between visible features and underground structures.

6. 6.

   You have been tasked to design an urban area near a known megathrust interface. What engineering considerations would you include based on hypocentre imaging?

   Hint

   Think about the physical characteristics of the region and how they inform design.
