Chile's massive Feb. 27 earthquake have shortened all of our days, according to NASA. The magnitude 8.8 quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second), citing a preliminary calculation by Jet Propulsion Laboratory scientists
the quake should have moved the "figure axis" (about which Earth's mass is balanced; offset about 33 feet off the north-south axis) by 2.7 milliarcseconds (about 3 inches), according to JPL research scientist Richard Gross.
