The nation of Japan is reeling today, trying to recover from a devastating natural disaster. The earthquake hit the island nation on Friday. It registered a magnitude of 8.9. That makes it the most powerful quake to hit Japan in at least 100 years. There were reports over the weekend that the quake moved the main of island of Japan -- the entire island -- by 8 feet!  The northeastern part of the country took the worst of it. This is what the water looked like rushing into one city. Some areas were completely flattened, with foundations the only sign of the buildings that once stood on them. You might think of a tsunami as this towering tidal wave that crashes down on shore.
