Question 1.
What does N represent in the Gutenberg-Richter Relationship?
Show hintHide hint
Think about what we're counting.
Question 2.
Name the two constants used in the Gutenberg-Richter equation.
Show hintHide hint
They're specific to region-focused analysis.
3Question 3.
What does the Gothic-Richter equation express?
- The relationship between wind speeds
- The number of earthquakes based on magnitude
- The depth of earthquakes
Show hintHide hint
Focus on the concept of frequency.
4Question 4.
True or False? A higher magnitude earthquake occurs more frequently than a lower magnitude earthquake.
- True
- False
Show hintHide hint
Recall the logarithmic aspect of the relationship.
Question 5.
In a region with constants a = 5 and b = 0.8, determine how many earthquakes of magnitude 7 or greater would be expected using the Gutenberg-Richter equation.
Show hintHide hint
Make sure to apply the logarithmic equation correctly.
Question 6.
Compare the risk of earthquake frequencies in two hypothetical regions, one with a=6 and b=0.5 and the other with a=4 and b=0.85. How would you relate their risks?
