Earthquake Magnitude - Linking Earthquake Magnitude and Intensity
Designed for an introductory geology course
Skills and concepts that students must have mastered
How the activity is situated in the course
Content/concepts goals for this activity
Higher order thinking skills goals for this activity
Other skills goals for this activity
Description of the activity/assignment
In this activity, students will model earthquakes of various magnitudes to determine the amount of shaking that these quakes will cause. They will then convert the shaking to modified Mercalli intensity and generate an isoseismal map for a M8 and M6 earthquake.
Uses geophysics to solve problems in other fields
Addresses student misconceptions
Determining whether students have met the goals
