24.8. Epicentre vs Isoseismal and Intensity Maps

Try these first

1. 1.

   What is an isoseismal map?

   Hint

   Think about how we represent areas of similar experience during an earthquake.

2. 2.

   Where is the epicentre usually found on an isoseismal map?

   Hint

   Recall what point experiences the highest shaking.

3. 3.

   Where does the epicentre lie in relation to an isoseismal map?

   • At the outer contour
   • At the innermost contour
   • In the middle

   Hint

   Think about where the strongest shaking is recorded.

4. 4.

   True or False: The intensity of shaking increases as you move away from the epicentre.

   • True
   • False

   Hint

   Consider how you feel when you are farther from an earthquake.

5. 5.

   Given an isoseismal map of a recent earthquake, identify how you might validate the epicentre location based on the intensity distribution observed.

   Hint

   Consider how each contour level corresponds to increasing or decreasing distance.

6. 6.

   Propose a method to enhance the accuracy of isoseismal maps in future earthquakes using technology.

   Hint

   Think about current technology advancements in data collection and processing.
