I have heard that the recent Tsunami has resulted in the rotational speed of the world shifting slightly and has knocked the sat nav satellites out of kilter!! Dunno by how much, but it goes to show the size of the quake!! > I have heard that the recent Tsunami has resulted in the rotational speed of > the world shifting slightly and has knocked the sat nav satellites out of > kilter!! > Dunno by how much, but it goes to show the size of the quake!!

There was something on the news about the earth was knocked of it's axis by an inch... bloke in work picked it up off the net somewhere, so dunno >> I have heard that the recent Tsunami has resulted in the rotational speed > of [quoted text clipped - 3 lines] > > Credible source, or bloke down the pub? > Credible source, or bloke down the pub? Have a dig on the web, a scientist from US Geological Survey seems to be the main source, nothing on the USGS website though. As for GPS the satellites are fine it's just that the world isn't where it's supposed to be.

Well I got up to the Lakes today ok using sat nav for part of the trip. It did say I'd got there when I was actually 2 doors away if that counts.

There were always far more targets than missiles, with vastly different priorities. Unless RAF Valley could take a fully loaded B-52, it'd be pretty low on the list. The same with nuclear reactors; they're not an immediate threat. SignatureDavid G. Bell -- SF Fan, Filker, and Punslinger. Wrought under license granted by Her Majesty's Apostropher Royal AD MMIV I think RAF valley is OK to take any aircraft - cant remember seeing the B52's at the shows but I was dragged along when I was a kid and was completely uninterested as my old man worked there for 30 odd years. > On Thursday, in article <cqvkd6$3ta$1@news6.svr.pol.co.uk> > [quoted text clipped - 11 lines] > the list.

My Sat nav (etrex) has worked fine all day to OS maps on Kinder. I wasn't the one who got lost in the mist and rain.

Mine was about 1/4 mile NE out of position coming back from work tonight. Any one else out of position?? > > I have heard that the recent Tsunami has resulted in the rotational speed > of [quoted text clipped - 3 lines] > > > Mine was about 1/4 mile NE out of position coming back from work tonight. And with that knowledge, how many hours sleep did you get last night? Personally I had the full eight hours, but some may feel that the sky is about to fall in on them. To whom..... hahahahaha!!! Steve > > Mine was about 1/4 mile NE out of position coming back from work tonight. > > And with that knowledge, how many hours sleep did you get last night? That particular bit of knowledge made not 1oz of difference to the amount of sleep I had, I got to bed around 2am, having finished the last of the nights breakdowns, was woken again at about 3am, to go and fix another one, back to bed for 4.30ish, then up at 7. Had I had any spare sleep to lose, I don't think I would have lost any worrying about the tom-tom being in the middle of a herd of cows, instead of in lane2 of the motorway!!! Found this on www.pocketgps.co.uk seems guy at work was not talking out of his arse!! Makes you think - what next? Following on from the worlds worst Tsunami's with a death toll figure furiously approaching 80,000, US based scientists from the Geological Survey (USGS) have said "the quake that set off the wall of water had moved tectonic plates beneath the Indian Ocean by up to 30 meters (100 feet), causing the Earth to wobble on its axis and permanently shortening the day by a fraction of a second. " which is a quote from Reuters. Science.orf.at in a Google Translation also says "The heavy earthquake before the coast of Sumatra has substantial geological effects. Thus the tectonic plates under the Indian ocean did not only shift experts according to around approximately 30 meters. Also the earth rotation could accelerate itself around three microseconds per day". This could adversely affect the Earth, satellites and GPS over a long period of time. >I have heard that the recent Tsunami has resulted in the rotational speed >of the world shifting slightly and has knocked the sat nav satellites out >of kilter!! > Dunno by how much, but it goes to show the size of the quake!! > Found this on www.pocketgps.co.uk > [quoted text clipped - 19 lines] >>of kilter!! >>Dunno by how much, but it goes to show the size of the quake!! Strange that though. I thought I recognized the back of head. Just hope we don't get anymore like these or else christmas will be coming too early next year.

Well it will be about 1mS earlier anyway but any excuse for the shops to start flogging Christmas stuf in August I guess. B-) SignatureCheers new5pam@howhill.com Dave. pam is missing e-mail > Makes you think - what next? Big metorite impact? There are 654 known Potentially Hazardous Asteroids, PHAs. Space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. An AU is the distance between the Earth and Sun and also note "known" quite a number are detected *after* they have come within closest approach... As far as known PHAs are concerned it's been a quiet couple of months, only 2 in Nov and 2 in Dec, closest was 5LD on the 24th Dec (Earth Moon distance or 0.0128AU). SignatureCheers new5pam@howhill.com Dave. pam is missing e-mail I remember seeing a program on that on discovery - one came down in Siberia in about 1908 I think - made a hell of a mess!!! >> Makes you think - what next? > [quoted text clipped - 7 lines] > only 2 in Nov and 2 in Dec, closest was 5LD on the 24th Dec (Earth > Moon distance or 0.0128AU). > I remember seeing a program on that on discovery - one came down in > Siberia in about 1908 I think - made a hell of a mess!!! Yep, and that was only 30m across and didn't actually hit the ground... http://www.psi.edu/projects/siberia/siberia.html SignatureCheers new5pam@howhill.com Dave. pam is missing e-mail > I remember seeing a program on that on discovery - one came down in Siberia > in about 1908 I think - made a hell of a mess!!! Tunguska, 1912, missed Western Europe by 4 hours. The Asian earthquake was roughly the equivalent of 450 megatonnes of TNT, If the latest asteroid predicted to pass us by in 2029 actually hit, it would be around 2000 MT.. Thats some bang !

That same google translation of a single web site is doing the rounds, I suspect it's one of those plausible-sounding nonsense stories. SignatureFor every expert, there is an equal but opposite expert > I have heard that the recent Tsunami has resulted in the rotational speed of > the world shifting slightly and has knocked the sat nav satellites out of > kilter!! > Dunno by how much, but it goes to show the size of the quake!! Quote from the United States Geological Survey.......... "Question: What effect did this earthquake have on the rotation of the earth? Answer: Richard Gross at JPL has modeled the coseismic effect on the Earth's rotation of the December 26 earthquake in Indonesia by using the PREM model for the elastic properties of the Earth and the Harvard centroid-moment tensor solution for the source properties of the earthquake. The result is: change in length of day: -2.676 microseconds polar motion excitation X : -0.670 milliarcseconds polar motion excitation Y: 0.475 milliarcseconds Since the length of the day can be measured with an accuracy of about 20 microseconds, this model predicts that the change in the length-of-day caused by the earthquake is much too small to be observed. And, since the location of the earthquake was near the equator, this model predicts that the change in polar motion excitation is also rather small, being about 0.82 milliarcsecond in amplitude. Such a small change in polar motion excitation will also be difficult to detect" |
