Explania is a good place to find video explanations and interactive images that explain all kinds of things from the worlds of science, technology, sports, and health. Today, on Explania I discovered this excellent animated explanation of tsunamis. The two and a half minute video explains how tsunamis are created and the impact of tsunamis when they reach land. The video is embedded below.

Unfortunately, the world saw plenty of footage last year of the tsunami in Japan. That provided plenty of visuals on the damage caused by tsunamis. This video provides a good way for students to see how a tsunami is formed. Here are a few other resources that you could also use in lessons about tsunamis: Tsunami Mapper, Tsunamis 101, Stop Disasters.
