20.9.1. Seismic Gaps

Try these first

1. 1.

   What is a seismic gap?

   Hint

   Think about what happens to faults over time without activity.

2. 2.

   Why are seismic gaps considered risky?

   Hint

   Consider what happens when stress builds up in materials.

3. 3.

   What is a seismic gap?

   • A section of an active fault that has not slipped recently
   • A place where earthquakes occur frequently
   • An area with no fault lines

   Hint

   Focus on the inactivity aspect of the fault.

4. 4.

   Are seismic gaps considered safe regions?

   • True
   • False

   Hint

   Think about the risks associated with inactivity on faults.

5. 5.

   Evaluate the consequences if a seismic gap near a populated area were to suddenly release.

   Hint

   Think about both immediate effects and longer-term recovery.

6. 6.

   Propose a public policy to mitigate risks associated with seismic gaps in urban areas.

   Hint

   Consider what measures can help keep communities safe.
