Violent Earth, produced by National Geographic, is a film about the causes of earthquakes, tsunamis, volcanic eruptions, and hurricanes. It's an excellent documentary if you have the time to watch it. But if you're searching for a shorter video explanation of the causes of tsunamis, National Geographic has something to fit that bill too. Tsunamis 101 is a three and one-half minute video about how a tsunami is caused and why they can be so deadly. The video is embedded below.
