29.4. Isoseismal Maps

Try these first

1. 1.

   What is an isoseismal map?

   Hint

   Think about how temperatures are shown on weather maps.

2. 2.

   What do isoseismal lines represent?

   Hint

   Consider how lines are used in topographic maps.

3. 3.

   What do isoseismal lines connect in an isoseismal map?

   • The depth of the earthquake
   • Points of equal intensity
   • Locations of seismic monitoring stations

   Hint

   Think about what you feel during an earthquake.

4. 4.

   True or False: Isoseismal maps can help identify areas of potential earthquake damage.

   • True
   • False

   Hint

   Consider how different regions respond to the same earthquake.

5. 5.

   Given an isoseismal map for a region after a magnitude 6 earthquake, analyze how different soil types could lead to varying intensities in different sectors of the map.

   Hint

   Consider examples from past earthquakes.

6. 6.

   Create a scenario where two cities experience the same earthquake but report different intensity levels based on isoseismal mapping. Explain the factors contributing to the differences.

   Hint

   Use real earthquake patterns to build your scenario.
