Yu Muroga was doing his job making deliveries when the 11 March 2011 earthquake hit in Japan. Unaware, like many people in the area, of how far inland the Tsunami would travel, he continued to drive and do his job. The HD camera mounted on his dashboard captured not only the earthquake, but also the moment he and several other drivers were suddenly engulfed in the Tsunami. He escaped from the vehicle seconds before it was crushed by other debris and sunk underwater. His car and the camera have only recently been recovered by the police. The camera was heavily damaged but a video expert was able to retrieve this footage.
Watch the pedestrian and note the car rocking at 0:10.
