If the earthquake redistributes rocks, can cause a slight imbalance in the mass balance planet speed . Since momentum is conserved , the alteration of the local mass also alter the speed . However, if nothing changes , it would be minutes, as in the order of 1.26 microseconds , it does not even feel . The Moon has much larger effects .

The massive 8.8 earthquake that struck Chile may have changed the entire Earth's rotation and shortened the length of days on our planet , a NASA scientist said Monday. The quake , the seventh strongest earthquake in recorded history , hit Chile Saturday and should have shortened the length of an Earth day by 1.26 milliseconds , according to research scientist Richard Gross of the Jet Propulsion Laboratory of NASA Pasadena , California
