August 23, 2011 Earthquakes in the U.S.
Yesterday in the Northeast United States, many of us felt the 5.8 magnitude earthquake that was centered 550 miles away from us in Virginia. There was also a 5.3 magnitude earthquake felt in Colorado.
Engage your students today with an activity that relates the Richter scale to the magnitude of the seismic energy released by the event. Students try to discover the exponential quality of the Richter scale with their own graphs, questions, and comparisons.
For members we have solutions, teacher tips, and sample graphs below.
