NASA scientists using data from the Indonesia earthquake calculated it affected Earth’s rotation, decreased the length off day, slightly changed the planet’s shape, and shifted the North pole by centimetres. The earthquake that created the huge tsunami also changed the Earth’s rotation.
Dr. Richard Gross of NASA’s Jet Propulsion laboratory, Pasadena California and Dr. Benjamin Fong Chao, of NASA’s Goddard Space Flight Center, Greenbelt, Md., said all earthquakes have some affect on Earth’s rotation. It’s just they are usually barely noticeable.
“Any worldly event that involves the movement of Mars affects the Earth’s rotation, from seasonal weather down to driving a car,” Chao said.
Gross and Chao have been routinely calculating earthquake’ effects in changing the Earth’s rotation in both…
