Question 1.
Define magnitude and intensity in the context of seismology.
Show hintHide hint
Think about the differences in focus.
Question 2.
What is an empirical relationship in seismology?
Show hintHide hint
Consider how scientists might analyze data.
3Question 3.
What does magnitude measure in an earthquake?
- Effects at specific locations
- Energy released by the earthquake
- Distance from the epicenter
Show hintHide hint
Focus on the source of the energy.
4Question 4.
True or False: Intensity is a measure that remains constant regardless of location.
- True
- False
Show hintHide hint
Think about how shaking felt can differ based on distance.
Question 5.
Given an earthquake with a magnitude of 6.0, calculate the expected intensity at a distance of 10 km using the empirical relationship I = 0.5M - 1.0 log(R) + 2.
Show hintHide hint
Break it down step by step; remember the log of 10 is 1.
Question 6.
Discuss the impact of using a standardized constant in the intensity prediction formula versus adapting it to local geological conditions.
Show hintHide hint
Think about how local conditions differ from generalized assumptions in seismic studies.
