19.5.2. Intensity

Try these first

1. 1.

   What is the MMI Scale used for?

   Hint

   Think about whether it's measuring strength or effects.

2. 2.

   What does an intensity of I mean?

   Hint

   Focus on what people would experience.

3. 3.

   What does the Modified Mercalli Intensity Scale measure?

   • The energy released by an earthquake
   • The audible sound of the earthquake
   • The effects of an earthquake

   Hint

   Remember, intensity is about feeling and impact.

4. 4.

   An intensity of XII indicates how much damage?

   • True
   • False

   Hint

   Think about the worst case situation.

5. 5.

   Evaluate the intensity of two hypothetical cities: City A is 10 km from the epicenter and experiences an intensity of VII, while City B is 50 km away but reports intensity of VI. Discuss discrepancies.

   Hint

   Think about local conditions that might change intensity.

6. 6.

   Based on historical earthquake impacts, propose mitigation strategies for urban areas regularly recording high intensity levels.

   Hint

   What can be done to minimize the effects of high-intensity earthquakes?
