28.3.1. Modified Mercalli Intensity Scale (MMI)

Try these first

1. 1.

   What does an MMI level of I indicate?

   Hint

   Think about how an earthquake may be perceived.

2. 2.

   How many levels are there in the Modified Mercalli Intensity Scale?

   Hint

   Recall the scale runs from I to a certain number.

3. 3.

   What does an MMI level of XII indicate?

   • Severe damage
   • Total destruction
   • Not felt

   Hint

   Think about what an absolute maximum level might describe.

4. 4.

   True or False: The Modified Mercalli Intensity Scale is based on instrumental readings.

   • True
   • False

   Hint

   Consider how the MMI collects its data.

5. 5.

   Discuss the potential limitations of using the MMI scale in areas with varying building practices and infrastructures.

   Hint

   Consider the role of building codes and practices in different regions.

6. 6.

   How would you assess the effectiveness of building regulations in earthquake-prone areas using MMI data?

   Hint

   Compare data across different buildings under similar conditions.
