Okay... here's a particularly poignant video of the tsunami hitting Minami-Sanriku, a small town on the coast of Miyagi-ken (Miyagi Prefecture) Japan back in March 11, 2011.
It's very difficult to watch, especially when you see a van and a truck enter a tunnel going toward the wave, and you know those people are dead. And then the others running for their life... and seeing the water and debris sweeping some of them away. And that man helping a person in a wheelchair... he got swept away at the end.
Made me friggin' cry.
Oh, and ignore the comments under the video. Some people are just ignorant when it comes to human suffering and feel the need to make everything into a political commentary.
