29.9. Intensity Prediction Equations (IPEs)

Try these first

1. 1.

   What does IPE stand for?

   Hint

   Is it related to predicting how something occurs?

2. 2.

   What does the magnitude in IPEs represent?

   Hint

   Think about what happens at the source of an earthquake.

3. 3.

   What do Intensity Prediction Equations (IPEs) estimate?

   • The magnitude of earthquakes
   • Expected intensity at a location
   • The epicenter of an earthquake

   Hint

   Consider what aspect of earthquakes IPEs focus on.

4. 4.

   True or False: IPEs do not consider local soil conditions.

   • True
   • False

   Hint

   Think about what influences the intensity predictions.

5. 5.

   A city experiences an earthquake where M = 7.0 at a distance of 50 km. Using a hypothetical IPE function, predict the intensity if the site is known to amplify shaking.

   Hint

   Think about how amplification changes perception.

6. 6.

   Evaluate a hypothetical scenario where IPEs fail to predict intensity due to unexpected geological conditions. Discuss potential improvements to the models.

   Hint

   What kind of local knowledge would assist in refining predictions?
