Are our GPS's now off 3" ?

 

Just heard that the 8.8 quake moved the Earth 3" on it's axis. Amazing the power of the planet.

Any smart people out there?

Do any of you smart people out there know this to be true. Being a dummy I just don't believe it.

Are our GPS's now off 3" ?

I recon they would be if they were that accurate to start with but since they are not -- well -- No.

Expect nothing!, appreciate benignity!

No Facts to this

Assumptions and nothing more, the reporter should have waited for facts. Sensationalism at it's best.

probably shifted

can involve shifting

The length of the day should have gotten shorter

should have moved by 2.7 milliarcseconds (about 8 centimeters or 3 inches

islands may have shifted

may have been raised 2 meters (6 feet)

Distance From The Sun Changed Too?

Didn't the Earth get a bit further from the sun the day after the quake compared to the day before? I also heard that we'll keep getting further until at least the middle of June.

I think I

I think I even weigh a little bit less, too!!!
I hope the 3" doesn't put us in the path of an unknown asteroid.

AND.......

The days are now 3 milliseconds shorter.

That means we all get less sleep

LOL

Time Lost

All employers will require that you work over to make up the lost time.

OK here goes the blonde thing again

Are you all joking. It isn't true is it? grin

We got another problem.

We got another problem. The rotation of the earth is slowing. Floating away from the earth is a much bigger problem than more snow falling on New York due to global warming. We gotta act now before its too late.

I have a question & I hear there is another big day coming

If I keep myself tethered will that keep me from floating away?

I also hear that on March 14th most of the United States will lose one whole hour of time at 2:00A.M. do to the shift of 3" after the quake.

Really...

Some people worry about the strangest things.

When an earthquake changes my GPS location by more than the accuracy of the unit (30 feet) I'll begin to start to think about if I should be worried.

Maybe.

This is a computation by a scientist at the Jet Propulsion Lab in Pasadena, Ca. The *figure* axis of the earth should have shifted by about 8cm in this quake. The figure axis is the axis that is the real balance of the mass of the earth and is about 10 meters from the rotational axis.

The earthquake quite likely slowed the earth's rotation by about 2.6 milliseconds, or about 2 year's worth of nominal slowing.

Again, this is a computation. The actual measurements will take some time.

To answer your original question, no. Your GPS is not now 3" off.

I'm sure the new model that you want will compensate for any and all variations caused by the earthquake. It probably had to be a hardware solution, so updating firmware may not compensate. It looks to me like you're getting that new GPSr. Enjoy!

So I'll weigh less the next time I step on the scale! COOL! mrgreen See honey, my diet IS working!

Let's start with :
*Chilean Quake Likely Shifted Earth’s Axis.
*Earthquakes can involve shifting.

This reminds me of our local weather men, that scare the hell out of everyone with coverage of a storm That is nothing more than a summer storm with the heaviest activity 50 miles to the south.
Why do they do this? because of computations and computer models with cloud rotations and what can happens. Only to be 99% wrong

When you have the proof and the facts then do the reporting, not a bunch of should have's and likely stuff. That's crap reporting at it's best even by a scientist at the Jet Propulsion Lab in Pasadena, Ca.

So an earthquake can shift the earth's axis???
Didn't know that, but there is a lot I don't know. Just a dumb blonde, well not so dumb but blonde. grin

Since Chile is south of us

Just move your gps south 3" to compensate for the error.

Are you just curious, or are

Are you just curious, or are you concerned about vehicle GPS units might be off 3"?

It does make me wonder if professional survey equipment using GPSs are now off, which would definitely be a problem since their work must be so exact.

Politicians and Diapers must be changed often for the exact same reason...

curious

i wish i would have paid more attention to what this scientist said . one thing i remember is he said it can be corrected . what is that correction ? just some intresting thought as after i got my nuvi 650 back from being repaired i went outside to acquire satellite signal . when i got the signal i pressed on signal strength and watched the accuracy ( from 40 feet went down to 27 feet ) . like i said how accurate and what do the earthquakes change ?
mike

accuracy

Non-military and non-survey GPS units are still accurate after the earthquakes.
Marine and aviation gps units display Elevation as well as Lat/Long lateral position, and the elevation is from Sea Level. The lateral position that most civillians use a gps for is completely unaffected.

Earthquakes cannot change average sea levels, but they might change the land elevation (sometimes significantly) in the area of the earthquake. And because of plate tectonics and subduction, there is some horizontal change. The pacific plate moves about 30 ft each 100 yrs.

Most interesting to me was the Chile earthquake changed distribution of earth's mass enough to shorten the length of each day by a millionth of a second.

The government should shorten each government employee's workday and benefits by that amount and help the deficit!

our gps accuracy

i saw an interesting discussion on the news the other day about earthquakes and how it effects the accuracy of gps . because of expansion and contraction of the earth during these events that or gps are thrown off so is there a correction done for this?

The top of the Mountain

Well, if we are here long enough, none of this will matter. The Sun will completely wipe us out when its fuel gets depleted and becomes an exploding ball that will leave nothing in our place but dust particles and some VERY big clouds of dust as well. They speculate 5 billion years, but then again... If we ARE around, we will then relive Superman's Jorel trying to leave a dying planet... I hope we have perfected space travel as well as the shielding required from gamma particles to survive the journey... Uh, BTW, Mars will be gone too...

We got another problem.

Besides Global Worming, now we have to fix Global Slowing. This probably was caused by all cars driving westward, thus pushing against the earth's rotation. This means there will be a new law that all cars will have to drive eastward only to speed-up the earth's rotation. (then again only with pollutant free cars).

Wouldn't that increase gravity?

I would think that the centrifugal force would offset some of the gravity. So slowing down the rotation would have the effect of INCREASING the gravitational pull.

I'm really glad to hear about the rotational slowing. I thought those extra pounds that show on the bathroom scale were a concern. Now I know it's the earth's rotation that's responsible, not those wonderful paczkis that my wife makes. mrgreen

FINALLY!!!

Edit

Relax, in 5 billion years you won't even be in anyone's memory. So your right it don't matter.
But by then your very distant ancestors, will have colonized another solar system with a young sun.

5 billion years! I guess Al Gore's theory might actually come to true, global warming at it most radical meaning.

3" Might get lost going

3" Might get lost going cross country

ocean tidal charts off

Because of the earthquake in Chili, all of the earths predicted tidal charts will be off, and need recalibration. Not to mention the earth will be farther away from the sun, and earth rotation slowing.

No worries

Unless your particular application requires pinpoint accuracy, you shouldn't lose sleep over the shift. smile

what aboutllll

what about daylight savings time. doesn't it throw off you sense to time managment as well smile

yup

Update

http://edition.cnn.com/2010/WORLD/americas/03/09/chile.earth...

Chile quake moves city more than 10 feet

The magnitude-8.8 earthquake that rocked the west coast of Chile last month was violent enough to move the city of Concepcion at least 10 feet to the west and the capital, Santiago, about 11 inches to the west-southwest, researchers said.

The quake also shifted other parts of South America, as far apart as the Falkland Islands and Fortaleza, Brazil.

The results were reached via global positioning satellite measurements taken before and after the February 27 quake by teams from The Ohio State University, the University of Hawaii, the University of Memphis and the California Institute of Technology, as well as agencies across South America.
