Try these first

1. 1.

   What is the primary purpose of ambient vibration testing?

   Hint

   Think about how this method gathers data.

2. 2.

   Define passive seismic arrays in one sentence.

   Hint

   Consider how these sensors are deployed.

3. 3.

   What is the main advantage of using ambient vibration testing?

   • It requires heavy machinery.
   • It is non-invasive.
   • It produces immediate results.

   Hint

   Consider methods that do not alter the tested environment.

4. 4.

   True or False: Passive seismic arrays are essential for measuring only dynamic forces during earthquakes.

   • True
   • False

   Hint

   Think about all types of seismic activity they can record.

5. 5.

   Devise a plan for using ambient vibration testing in a city that has recently experienced a significant earthquake. What factors would you consider?

   Hint

   Consider areas previously affected by seismic activity.

6. 6.

   Evaluate the effectiveness of passive seismic arrays in terms of real-time earthquake monitoring. What are the strengths and weaknesses?

   Hint

   Think about the roles of sensor networks in other fields like weather monitoring.
