Today earthquake in Japan shifted the earth’s rotation axis by 10 cm.
As a result of the earthquake in Japan on March 11, the Earth’s rotation axis has shifted by almost 10 centimeters(4 inches) It’s the preliminary result of studies carried out by INGV, National Institute of Geophysics and Volcanology.
Chile earthquake in March 2010 was already so powerful that it shifted as well an Earth axis and shortened the length of a day, NASA announced few days later.
By speeding up Earth's rotation, the magnitude 8.8 earthquake—the fifth strongest ever recorded, according to the USGS—should have shortened an Earth day by 1.26 millionths of a second, according to new computer-model calculations by geophysicist Richard Gross of NASA's Jet Propulsion Laboratory in California.
