21.15. Blind Faults and Hidden Seismic Sources

Try these first

1. 1.

   What is a blind fault?

   Hint

   Think of what happens in the ground.

2. 2.

   How can buried ruptures affect buildings?

   Hint

   Consider how buildings might respond to hidden earthquakes.

3. 3.

   What is the main characteristic of a blind fault?

   • Visible on the surface
   • Undetected underground
   • Fluctuates unpredictably

   Hint

   Think about what makes a fault 'blind'.

4. 4.

   True or False: Buried ruptures can produce strong seismic waves without surface rupture.

   • True
   • False

   Hint

   Recall the effects of an underground fault.

5. 5.

   Evaluate the implications of blind faults on existing urban infrastructure and propose methodologies to assess their presence.

   Hint

   Think about how cities might protect themselves from surprise seismic events.

6. 6.

   Design a research study aiming to investigate the frequency and impact of buried ruptures in sedimentary basins.

   Hint

   Consider the steps needed to gather essential data.
