19.5. Earthquake Magnitude and Intensity

Try these first

1. 1.

   What does the Richter Scale measure?

   Hint

   Think about energy and earthquakes.

2. 2.

   What is intensity used to assess?

   Hint

   What do we feel during an earthquake?

3. 3.

   What does the Moment Magnitude Scale measure?

   • Frequency of earthquakes
   • Energy released
   • Intensity of shaking

   Hint

   Think about measuring the earthquake's power.

4. 4.

   True or False: The Modified Mercalli Intensity Scale has a range from I to XII.

   • True
   • False

   Hint

   Remember the scale's range.

5. 5.

   Given a scenario where an earthquake registers magnitude 8.0, discuss the likely intensity effects in an urban area compared to a rural area.

   Hint

   Consider how buildings are built differently.

6. 6.

   Evaluate a situation where local soil conditions amplify earthquake vibrations and analyze its implications on safety measures.

   Hint

   Think about building materials and designs.
