25.4.3. Inversion Techniques

Try these first

1. 1.

   What is the primary purpose of inversion techniques?

   Hint

   Think about what information is gained regarding earthquakes.

2. 2.

   Name one type of seismic wave used in inversion techniques.

   Hint

   Consider which waves arrive first during an earthquake.

3. 3.

   What do inversion techniques primarily help to estimate?

   • Hypocentre location
   • Epicentre depth
   • Magnitude of earthquakes

   Hint

   Focus on what inversion techniques specifically address.

4. 4.

   True or False: S-waves arrive before P-waves at seismic stations.

   • True
   • False

   Hint

   Remember the sequence of wave arrivals during an earthquake.

5. 5.

   Explain how the estimation of a hypocentre's depth might change based on different models of seismic wave propagation.

   Hint

   Consider how the Earth's layers might affect wave speed and behavior.

6. 6.

   Critique the effectiveness of inversion techniques in predicting aftershocks following a major earthquake.

   Hint

   Look at the role of stress redistribution in the crust.
