A major earthquake (magnitude 7.0) occurred Tuesday in the boundary region separating the Caribbean plate and the North America plate. This plate boundary typically moves only about 20 millimeters per year, with the Caribbean plate moving eastward with respect to the North America plate.  However, its sudden shift Tuesday caused an unbelievable human catastrophe.  Educational materials are available for the devastating earthquake that hit Haiti last week. The materials, put together by the Incorporated Research Institutions for Seismology, are on the following website: http://www.iris.edu/hq/programs/education_and_outreach/moments

The materials can help students look at the science behind this horrible disaster, and to help them answer questions like, “So why didn’t this magnitude 7 earthquake cause a large tsunami?” or “Why did this earthquake cause such massive building destruction?”
