Chilean Earthquake Shifted Earth's Poles

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.
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).

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 in 500 (edit by Alex 3/3/10 - more like 25 million) years or so, sunrise will be around 10:30 PM. Link

Yeah...it may have been sarcastic, but it's pretty misleading for someone who didn't do the calculation themselves quickly. It won't significantly affect the light/dark cycle of the day for hundreds of thousands to millions of years.

@David: np :)

@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.

It will take about 7.8 million years for the time to roll back 1 hour.

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.

I heard this today and thought someone was joshing me. WOW. Pretty amazing to consider. Just makes me think that we are incredibly blessed on this planet in the face of how powerful mother nature is.

Either way, it's no biggie if days get a tiny bit longer, because we are already using leap seconds (http://en.wikipedia.org/wiki/Leap_second) to keep them from shifting throughout the years.

at least amend the article.

10.30 sunrise is all i'll remember in a few days time.

thanks for putting more shite into my brain, doofus.

For someone who is not really good in math, the initial facts are pretty striking. However, I felt far better after reading the computations. Good work guys :> the fact is, the earthquake did shorten the day... a little bit.

Search up H.A.A.R.P. on Google or youtube. There have been some stuff about HAARP, an program conducted by the US Government is testing this stuff. They say HAARP is the blame for this, it creates activity that can change weather and etc. Theres a lot of information about it and controversies. I strongly believe that HAARP has been causing all these disaster. I can be proved wrong but everyone can believe what they believe.
