Earthquake in Chile shifts the Earth’s axis and shortens day
It is really tough to notice, but yes, its true the Earth’s days have gotten shorter since the huge earthquake in Chile, the Earth is about one-millionth of a second faster now.
Scientist Richard Gross, at NASA’s Jet Propulsion Laboratory in Pasadena, California calculated only to find that on Saturday the earthquake made the day less by 1.26 microseconds. The question here is how much is one microsecond? Answer to this one is, one-millionth of a second is one microsecond.
86,400 seconds or 24 hours is the length of one day and the amount of time our Earth takes to complete one rotation. But an earthquake can make the earth go a little more faster than normal conditions resulting in some mass closer to the axis of the planet.
Richard Gross also stated that these changes are permanent but very very small, so small that scientist can record it themselves. He further said.
“I’ll certainly look at the observations when they come in, but “I doubt I’ll see anything.”
