Japan earthquake speeds earth spin, shortens day
The massive earthquake that struck northeast Japan Friday (March 11) has shortened the length Earth's day by a fraction and shifted how the planet's mass is distributed.And those 1.8 microseconds better come off the 8 to 5 work day and not off the free time part of the day. We have barely have enough time to get the grocery shopping and other errands done as it is.
A new analysis of the 8.9-magnitude earthquake in Japan has found that the intense temblor has accelerated Earth's spin, shortening the length of the 24-hour day by 1.8 microseconds, according to geophysicist Richard Gross at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
