Question 1.
What is the Elastic Rebound Theory?
Show hintHide hint
Think about the behavior of a stretched rubber band.
Question 2.
What is seismic moment (M₀)?
Show hintHide hint
This measure includes rigidity, area, and displacement.
3Question 3.
What is the key concept of the Elastic Rebound Theory?
- Stored energy in rocks is released when they break
- Rocks compress without any movement
- Rocks move continuously along the fault
Show hintHide hint
Think about the release of stored energy during an earthquake.
4Question 4.
True or False: A larger seismic moment indicates a more powerful earthquake.
- True
- False
Show hintHide hint
Link this to the concept of fault size and displacement.
Question 5.
Using recent earthquake data, calculate the seismic moment for an earthquake that had a fault displacement of 3 meters, with an area of 50 km² and a rigidity modulus of 30 GPa.
Show hintHide hint
Make sure to convert units correctly to maintain consistency in calculations.
Question 6.
Analyze the impact of a locked fault on surrounding infrastructure during a sudden rupture event.
Show hintHide hint
Consider how stress accumulation over time affects buildings and infrastructure.
