Question 1.
What does 'I' represent in the empirical relationship formula?
Show hintHide hint
It's the outcome measured during an earthquake.
Question 2.
What is the purpose of the constants 'a', 'b', and 'c'?
Show hintHide hint
They're tailored numerical values.
3Question 3.
What is the role of empirical relationships in seismology?
- To predict space weather
- To relate seismic intensity with magnitude
- To measure global temperatures
Show hintHide hint
Focus on the purpose of predicting earthquake effects.
4Question 4.
True or False: The constant 'c' affects the relationship between intensity and distance.
- True
- False
Show hintHide hint
Think about what each constant does in the formula.
Question 5.
A seismic event has been recorded with a magnitude of 6.5 at a distance of 50 km. Apply the formula I = 2M - 1log(R) + 4 and determine the intensity.
Show hintHide hint
Break down the components step by step.
Question 6.
How would altering the constant 'a' to a larger number impact the predicted intensity of earthquakes in a highly urbanized area?
Show hintHide hint
Think about urban sensitivity to shaking.
