This video shows the giant tsunami that stemmed from the March 11 earthquake which hit Japan's Fukushima Daiichi power plant.
It was shot by a plant worker at the Tokyo Electric Power Company who escaped before it hit. The wave was supposedly 45-48 feet higher than normal sea levels.
On Thursday, workers at the plant were forced to evacuate after another powerful earthquake shook northeast Japan, roughly a month after a quake and tsunami killed about 28,000 people.
