    Parts of Japan are now 13 feet higher, and some 2 feet lower.  The Earth’s axis has also shifted 4 inches.  Check out this information and more in a recent post in GreenAnswers news!

    There are estimates that the quake has caused a the Earth to rotate a bit faster, shortening the length of the day by about 1.8 microseconds. 

    The calculations also show the quake may have shifted the position of Earth’s figure axis (the axis about which Earth’s mass is balanced) by about 17 centimeters (6.5 inches), towards 133 degrees east longitude.

    Both of these initial calculatons could and probably will changes as data on the quake are further refined.

    The entire island was also moved 8 feet east, after the quake.

    I actually read that following the quake, Japan had shifted by  four meters (approximately 13 feet) eastwards. There were also changes of up to three feet in water depths along Japan’s coastline. Also, in terms of plate tectonics, the Pacific plate itself has shifted approximately 20 meters westward.

    The earth has shifted on its axis by about 4 inches.

    The main island of Japan has slid 8 ft. to the east.
