The earthquake in Japan was so powerful that it changed the earth's axis, sped up the earth's rotation by 1.6 microseconds, and moved a portion of Japan's land mass by 2.5 meters.
The island of Honshu moved eight feet to the east. The change in the earth's rotation will make the day a tiny bit shorter, by about one millionth of a second.
Antonio Piersanti, a researcher at the Italian Institute of Geology and Volcanology, claims that the earthquake has shifted the earth's axis by 3.937 inches. As earthquakes involve the moving of rock from one place to another, and rocks have significant weight, it's not surprising that the biggest quake in Japan's history would have this effect.
We can see below that the mega-powerful tsunami was so potent that it moved Japan’s coastline 8 feet and shifted the earth’s axis. See the before and after NASA photos below.
