Question 1.
What does saturation refer to in magnitude scales?
Show hintHide hint
Think about what happens to measurements when quakes are very large.
Question 2.
Explain what regional calibration means.
Show hintHide hint
Consider how different areas might impact measurement effectiveness.
3Question 3.
What is one reason why the Richter scale becomes less effective for earthquakes greater than magnitude 6.5?
- It saturates
- It's too sensitive
- It's inaccurate at distance
Show hintHide hint
Remember the concept of saturation related to large quakes.
4Question 4.
True or False: Instrumentation dependency refers to the fact that all instruments measure vibrations with the same sensitivity.
- True
- False
Show hintHide hint
Think about how different tools can affect results.
Question 5.
Given a hypothetical earthquake data set showing saturation at magnitude 7.0 and comparing it to a moment magnitude scale reading of 7.5, explain the likely discrepancies observed.
Show hintHide hint
Explore how each scale captures energy differently.
Question 6.
Design an experiment to test how regional geology might influence seismic reading accuracy. Outline your approach.
Show hintHide hint
Think about steps for comparative analysis.
