25.4.2. Seismic Tomography

Try these first

1. 1.

   What is seismic tomography?

   Hint

   Think about what we can use seismic waves to visualize.

2. 2.

   Why is the location of the hypocentre important?

   Hint

   Consider how knowing where something starts can help in many fields.

3. 3.

   What is the main purpose of seismic tomography?

   • To create surface maps
   • To generate 3D images of Earth's interior
   • To track earthquakes

   Hint

   Think about what insights are gained from internal images.

4. 4.

   True or False: Seismic waves travel faster through denser materials.

   • True
   • False

   Hint

   Consider how density affects wave propagation.

5. 5.

   Using a simple 2D modeling software, simulate how variations in rock density would affect wave travel times for seismic tomography.

   Hint

   Focus on how different materials interact with wave propagation.

6. 6.

   Consider a region with known seismic activity. Propose a study using seismic tomography to improve building codes in that area, outlining the steps you'd take.

   Hint

   Think about the entire process from data collection to analysis and application.
