Question 1.
What is an isoseismal map?
Show hintHide hint
Think about how intensity is measured across different areas.
Question 2.
Where is the epicentre typically found on an isoseismal map?
Show hintHide hint
Consider where the strongest shaking is observed.
3Question 3.
What does an isoseismal map display?
- Time of the earthquake
- Points of equal seismic intensity
- Distance from the epicentre
Show hintHide hint
Focus on what these maps represent tangibly after an earthquake.
4Question 4.
The epicentre is generally found at which location on an isoseismal map?
- At the outermost contour
- At the innermost contour
- Distributed randomly
Show hintHide hint
Think about where the strongest shaking occurs.
Question 5.
Given an example isoseismal map from a recent earthquake, outline the steps to identify and analyze the epicentre's location and intensity variations.
Show hintHide hint
Refer back to the definitions of epicentre and intensity.
Question 6.
