Earthquake Magnitude - Linking Earthquake Magnitude and Intensity
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process.
This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.

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
