21.7. Mapping and Identification of Faults

Try these first

1. 1.

   What is geological mapping?

   Hint

   Think about how we can see faults from the surface.

2. 2.

   Give one example of how remote sensing can be used in fault identification.

   Hint

   Consider what satellite images can reveal.

3. 3.

   Which method involves physically excavating to find evidence of past fault activity?

   • Geological Mapping
   • Trenching
   • Remote Sensing

   Hint

   Consider which method involves tools and labor.

4. 4.

   True or False: Remote sensing can only be used for geological mapping, not for fault identification.

   • True
   • False

   Hint

   Think about the different applications of remote sensing.

5. 5.

   Design a study incorporating geological mapping, remote sensing, and trenching to identify a fault in a rural area. What steps would you take and what information would you aim to uncover?

   Hint

   Think about combining techniques for a comprehensive approach.

6. 6.

   Evaluate the effectiveness of seismic studies in predicting seismic hazards in an urban environment. What limitations might they have?

   Hint

   Consider the implications of hidden dangers.
