THE devastating earthquake that has killed over 700 people in Chile and displaced over two million more has now caused our days to be slightly shorter.
Not only has it shortened the day, it shifted the axis.
But scientists say the shifting in the tectonic plates has also shifted the Earth's axis.
The Earth’s overall mass distribution has likely been altered which has made the length of a day 1.26 microseconds shorter, NASA scientists say."The axis about which the Earth's mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimetres or 3 inches)
"It’s what we call the ice-skater effect,” David Kerridge, head of Earth hazards and systems at the British Geological Survey in Edinburgh told Bloomberg.
“As the ice skater puts when she’s going around in a circle, and she pulls her arms in, she gets faster and faster. It’s the same idea with the Earth going around if you change the distribution of mass, the rotation rate changes.”
