National Geographic Video - Tsunamis 101

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.

Violent Earth is available to view for free in its entirety on Snag Films. The first three minutes of it is included in the video below.
