The Chilean earthquake that killed more than 700 people on Saturday probably shifted the Earth's axis and shortened the day, according to a NASA scientist.

Richard Gross, a geophysicist at NASA's Jet Propulsion Laboratory in Pasadena, California, told Bloomberg that the 8.8-magnitude quake is likely to have moved the Earth's axis by 2.7 milliarcseconds - about 8 centimetres - and shorted the day by about 1.26 microseconds.
