NASA: Chilean earthquake may have abridged earth day by microsecond

The earth quake that rocked the South American nation may have also knocked the Earth off its axis.

The 8.8-magnitude earthquake near Chile could have also made our planet's days shorter, as said by NASA scientist Richard Gross.

A small change in the Earth’s axis isn't expected to alter much in terms of weather. The planet's tilt influences the seasons, allowing for winter, spring, summer and fall, and it would take a far greater change in the Earth's axis to have an impact on them.

The Chile quake could have moved the Earth’s axis by about 3 inches, Richard Gross said.

The quake also shortened the day by 1.26 microseconds, the scientist dogged, using a complex model he and others developed.

The Earth's rotation was possible affected by the shift in the planet's mass, which may cause it to spin faster.

Scientists believe other quakes, like the 2004 9.1-magnitude earthquake in Sumatra, have also decreased the Earth's day. That quake is believed to have abridged it by 6.8 microseconds, also altered the axis by almost 7 inches.
