After the 9.0 magnitude earthquake in Japan a week ago, scientists guess that days on earth might be shorter now. The quake might also have moved the Earth´s axis.
Complex calculations indicate that the quake might have caused the Earth to rotate faster. Our days are now supposedly 1.8 microseconds shorter than before. Earth´s axis position might have shifted 6.5 inches.
However, both changes are not noticable for mankind.
The earthquake in Japan was the fifth largest since 1900.
