Witness: Disaster in Japan is a documentary produced by National Geographic that shows us a compilation of videos of what happened on the 11th of March. It shows images from the less affected areas like Tokyo or Saitama, as well as images from the most affected areas, devastated by the tsunami, like Miyagi and Fukushima. The documentary is edited so that is shows what happened in a chronological way, since the earthquake strikes until the tsunami hits 20-30 minutes after, depending on the area.
