Question 1.
Define magnitude in the context of earthquakes.
Show hintHide hint
Think about what it tells us about the earthquake's strength.
Question 2.
What does intensity measure?
Show hintHide hint
Consider how people experience earthquakes differently based on location.
3Question 3.
What does magnitude measure in an earthquake?
- The shaking felt
- Energy released
- Structural damage
Show hintHide hint
Think about the scale that scientists use.
4Question 4.
True or False: Intensity and magnitude mean the same thing.
- True
- False
Show hintHide hint
Recall their distinct definitions.
Question 5.
A magnitude 5.5 earthquake occurs 10 km from a city. Using the formula I = aM + b log(r) + c (a, b, c constants provided as 1, 0.5, 2), calculate the estimated intensity.
Show hintHide hint
Calculate log values first then substitute back.
Question 6.
Discuss how an earthquake of magnitude 7.0 could lead to high intensity values in a poorly constructed area despite its distance.
Show hintHide hint
Consider structural factors and soil types.
