Interesting... A new analysis of the 8.9-magnitude earthquake in Japan has found that the intense temblor has accelerated Earths spin, shortening the length of the 24-hour day by 1.8 microseconds, according to geophysicist Richard Gross at NASAs Jet Propulsion Laboratory in Pasadena, Calif. Gross refined his estimates of the Japan quakes impact – which previously suggested a 1.6-microsecond shortening of the day – based on new data on how much the fault that triggered the earthquake slipped to redistribute the planets mass. A microsecond is a millionth of a second. SPACE
