Update 4/23/11 - A friend e-mailed me this video which is a new one to me. It shows the huge tsunammi wave making it's way across farmland, plus a lot more.
Gizmodo (HT: Allahpundit) describes the video below:
We've seen a lot of scary videos of this month's deadly Japanese earthquake and tsunami — but nothing like this. Watch as the waves ravage the port of Kesennuma, destroying everything in it's path.
First watch as the tsunami begins by tossing cars around like toys at the port parking lot — and then watch how terrifyingly fast the rest of the city becomes enveloped in water. In the end, only a couple of buildings survive.
