The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day.
JPL research scientist Richard Gross computed how Earth’s rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second).

Also, as a result of the earthquake, there is a lot of activity on Amateur Radio frequencies of 7050, 7060, 7088, 7095. As there is a contest next weekend, please listen carefully before using these frequencies. More.
