26.6.1. S-Wave Measurement

Try these first

1. 1.

   What is an S-wave?

   Hint

   Think about their motion and the materials they can propagate through.

2. 2.

   Name one method used to measure S-waves.

   Hint

   Consider the types of tests discussed.

3. 3.

   What method involves placing a geophone in a borehole?

   • Cross-hole test
   • Down-hole test
   • Seismic reflection

   Hint

   Focus on the method that uses depth measurements.

4. 4.

   True or False: S-waves can travel through fluids.

   • True
   • False

   Hint

   Think about the nature of wave propagation in different materials.

5. 5.

   You are tasked with assessing a site for a new building. Describe how you would use down-hole and cross-hole tests to gather necessary data.

   Hint

   Think about the order of operations and what data is most important for construction.

6. 6.

   Explain how seismic refraction can be used to identify a buried fault line and its potential implications for construction.

   Hint

   Consider how wave speed changes correlate with geological changes.
