Earthquake intensity

In this activity, students study damage descriptions from earthquakes and allocate a Modified Mercalli Intensity (MMI) number.

By the end of this activity, students should be able to:

• understand the Modified Mercalli Intensity (MMI) scale

• look at damage descriptions of historic New Zealand earthquakes and allocate Modified Mercalli Intensity scale numbers to them

• understand the difference between magnitude and intensity of earthquakes.
