The 8.8 magnitude earthquake in Chile apparently had some profound effects on this giant spinning rock we live on. NASA calculated that the figure axis, along which Earth's mass is balanced, shifted by about eight centimeters.
It also disrupted the Earth's rotation, shortening each day by 1.26 microseconds. No worries, though, because at that rate we shouldn't notice any real effects for a while, but in500 (edit by Alex 3/3/10 - more like 25 million) years or so, sunrise will be around 10:30 PM. Link

Perhaps more impressive is how much the quake shifted Earth's axis. Gross calculates the quake should have moved Earth's figure axis (the axis about which Earth's mass is balanced) by 2.7 milliarcseconds (about 8 centimeters, or 3 inches). Earth’s figure axis is not the same as its north-south axis; they are offset by about 10 meters (about 33 feet).

@Alex: that's right. Now imagine how violent was the one that happened in 1960, at 9.5. I also wonder how the planet was affected at that time.
This isn't actually what happens, though. The Earth goes through a lot more than just a slowing of rotation. The precession, obliquity, and tilt change much faster than that.
10.30 sunrise is all i'll remember in a few days time.
thanks for putting more shite into my brain, doofus.
