LOS ANGELES, March 12. / Correspondent. Itar-Tass Kachalin /. The massive earthquake in Japan has shifted its axis of the Earth / the planet around which the mass balance / 15 cm to reduce the length of Earth's day by 1.6 microseconds.
These preliminary estimates cited in an interview with Itar-Tass scientist Richard Gross of NASA's Jet Propulsion Laboratory, located in Pasadena / California /.
Experts estimate that the Italian National Institute of Geophysics and Volcanology Centre of Geodesy and the Italian Space Agency / ICA / after earthquake in Japan shift the Earth's axis was 10 cm
Available NASA there is no exact results of specific observations, but there are estimates, said Ross. "These calculations indicate that the length of Earth's day was shortened by 1.6 microseconds, and the axis around which the mass balance, was shifted by 15 cm in the direction of the 139 degrees east," — said the laboratory. He explained that the proper axis of the Earth, which is not to be confused with the axis of rotation of the planet, "shifted constantly" under the influence of any event that causes a change in the mass distribution of large objects on the surface. "Length of days is changing, just as the skater increases the speed of the body on the ground, pressing his hands to his sides. Earthquake in Japan shifted the mass of the Earth so that the planet was spinning faster. Accordingly, the duration of the day was reduced "- continued Ross.
He compared the cataclysm in Japan since last year's earthquake off the coast of Chile. It shifted the Earth's own axis by 8 cm in the direction of the 112th degree east longitude, and reduced the length of a day by 1.26 microseconds. Thus, the Japanese earthquake shifted the axis by almost two times more than the Chilean, noted scientist, adding that in 2010 used the same model calculations, it is now.
"For our planet on a global scale, such powerful tremors devastating consequences do not bear," — says Ross. "Own the Earth's axis is shifting all the time in the pressure in the atmosphere, moving bodies of water in the oceans and other phenomena. These factors are much more powerful than the calculated effect of the earthquake, "- concluded NASA scientist.
