Locating and Measuring Earthquakes Using Real Seismic Data
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.
This activity was selected for the On the Cutting Edge Reviewed Teaching Collection
This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are
- Scientific Accuracy
- Alignment of Learning Goals, Activities, and Assessments
- Pedagogic Effectiveness
- Robustness (usability and dependability of all components)
- Completeness of the ActivitySheet web page
For more information about the peer review process itself, please see http://serc.carleton.edu/NAGTWorkshops/review.html.

Description of the activity/assignment
- Step one: Point your web browser to Virtual Earthquake to start
- Step two: Read the instructions on that page, select an earthquake, and click on Submit Choice.
- Step three: View the seismograms, measure S-P intervals, convert them, determine the distances from the earthquake to the 3 stations using a chart provided on the page, and compare your results with the real epicenter. If you get an "Ooops" or "you are close". you have to re-measure the S-P intervals and the distances.
- Step four: After the earthquake is located, go on to determine its Richter magnitude.
- Step five: Get yourself certificated as a "Virtual Seismologist". Print out the page which contains the Certificate and the Final Data Summary that shows what you have entered. Turn in this page with your name and ID at the top to receiver credit.
