Chile Earthquake may have changed the Earth

The massive 8.8 earthquake that struck Chile may have changed the entire Earth's rotation and shortened the length of days on our planet, a NASA scientist said Monday.


Quote:

The quake, the seventh strongest earthquake in recorded history, hit Chile Saturday and should have shortened the length of an Earth day by 1.26 milliseconds

Also, the earthquake may have shifted the Earth's axis by 3 inches. This means the whole rotation of the Earth also changed.

This proves that an earthquake doesn't just affect a certain area, it can affect the whole world. This one is no exception.

Wow! That's just... mind-blowing. I had no idea that earthquakes could affect the whole planet to such an extent. I mean, 1.26 milliseconds isn't much, but still...

I've also heard that building man-made dams can affect the earth's rotation...

"Because of the number of dams which have been built, the Earth's daily rotation has apparently sped up by eight-millionths of a second since the 1950s."

Are you sure it's sped up and not slowed down?
