The Japanese below the film reads “Great East Japan Earthquake.” That’s one of the names for the huge quake that hit in 2011 and caused the horrific tsunami. And the time stamp on the video confirms it’s from the moment the big quake hit.
You don’t really need to understand the audio. It’s interesting to watch the seismometer at the bottom of the film, which is paired up perfectly with the video.
About two minutes in, the ground starts to split, and you’re literally watch the earth, live, rip itself apart. It looks like a Hollywood movie.
About 5 minutes in there’s another scene of people in a lecture hall, and you watch the seismometer on the bottom, seeing that the quake is about to hit, but they don’t know it. It’s mesmerizing.
The other interesting thing to note is that while everything is thrown around like crazy, the buildings for the most part don’t fall down. Rather amazing engineering involved here.
