The earthquake in Chile is calculated to have shortened the day by 1.26 μSec and shifted the earth's axis by 8cm.

A JPL computer model suggests that the length of the Earth day may have been shortened by 1.26 millionths of a second.

The change in the length of the day came as a result of the shift in the Earth's axis that occurred because of the quake.

The Earth's axis shifted by 2.7 milliseconds of arc, or about eight centimetres.
