Here are a few teaching resources that may be useful for faculty and staff when teaching about the earthquake in Haiti. It’s just a few things I happen to have come across, so feel free to suggest others.
This page from IRIS (Incorporated Research Institutions for Seismology) contains a number of resources for helping students understand what happened geologically. There are downloadable PowerPoint presentations, videos and animations such as this one explaining why the quake didn’t produce a tsunami.
