21.17. Instrumentation and Monitoring of Fault Activity

Try these first

1. 1.

   What does InSAR stand for?

   Hint

   Think of a technique that uses satellites.

2. 2.

   What is the role of GPS in fault monitoring?

   Hint

   Consider a system used for navigation.

3. 3.

   What is the primary purpose of monitoring active faults?

   • To prevent earthquakes
   • To predict earthquakes
   • To map the geography

   Hint

   Consider why we use monitoring systems.

4. 4.

   True or False: Strainmeters measure crustal deformation.

   • True
   • False

   Hint

   Think about what they assess.

5. 5.

   Design a monitoring system for a hypothetical active fault. Discuss the benefits of integrating multiple instruments like GPS, seismographs, and strainmeters.

   Hint

   Consider how each technology complements the others.

6. 6.

   Analyze the advantages and disadvantages of using remote sensing techniques like InSAR compared to terrestrial monitoring techniques for fault evaluation.

   Hint

   Think about the trade-offs in detail and distance.
