NASA confirms that the earthquake shook the Earth's axis and shortened the day

Washington, March 16 (EFE) .- The Earthquake of 9 magnitude on the Richter scale that hit Japan last March 11, should have changed the Earth's axis and shortened days, according to NASA scientists. Continue reading the printed article 
- PHOTO AND VIDEO RELATED His calculations indicate that changing the distribution of the mass of Earth, the earthquake in Japan must have caused the earth to run a bit faster, shortening the length of a day about 1.8 microseconds (a microsecond is one millionth of a second).
- investigator Jet Propulsion Laboratory (JPL) of NASA Richard Gross and his team have implemented a complex geological model for a preliminary theoretical calculation of how the earthquake in Japan, and the fifth largest since 1900, has affected to the rotation of the Earth. The calculations also indicate that the earthquake Japan should have changed the position of Earth's axis (around which the mass balances of our planet) about 17 centimeters in the direction 133 degrees east longitude.
- NASA said in a statement that both estimates will likely change as the earthquake data are more precise. Gross estimated the magnitude 8.8 earthquake that occurred in Chile last year should have shortened the length of the day at about 1.26 microseconds and shifted the axis of the Earth in about 8 inches.
As explained Gross, in theory, any phenomenon that redistributes the mass of the Earth will change the planet's rotation.
"The rotation of the Earth changes all the time not only as a result of the earthquake, but also major effects such as changes in atmospheric winds and ocean currents," he said.
