The recent earthquake in Chile was the seventh largest ever recorded.
We know it caused an enormous amount of damage.
Scientists also think it did a whole lot more that we can't see.
The Earth rotates on an axis and that's how we measure our days, but scientists believe the recent earthquake altered the axis and time.
Good question: Can an earthquake really shorten my day?
Zhenming Wang is a University of Kentucky Seismologist and he studies earthquakes everyday.
"In the last month or so we already saw several of them, one in Chicago." said Wang.
While many are small in nature, the 8.8 quake that hit Chile was devastating.
Scientists think it was powerful enough to actually shift the earth's axis, some data indicates by three inches and that scientists think caused the length of the day to be shortened.
Would we really even notice?
" I think for a normal person really no," said Wang.
Wang says we are talking millionths of a second, many of us too busy to to notice.
One Earth day is 24 hours, over the course of a year it can be longer or shorter by just milliseconds.
Scientists think this latest quake shortened the day by 1.26 milliseconds.
The earthquake in Chile has killed some 700 people.
