The last time anyone checked on Australia was way back in 1994. Suspecting it had gone missing, scientists recently went looking for Oz and discovered it had moved to a new position north of where it used to be. Not only that, Australia is cruising northward at a rate of knots making it the Fastest Continent on Earth.
The change is so dramatic that Global Positioning Systems (GPS or Satnav) will need to be recalibrated to reflect the continent’s new address. (This GPS anomaly may help to explain why so many Australians get lost on the way home these days. Cruise ships, heading for Melbourne, are also reported to be regularly bumping into Tasmania.)
The reason for all this chaos? – it’s the Tectonics! Australia sits on the Australian Continental Plate which is sliding north at the rate of 7 centimetres (2.75 inches) a year making it the fastest moving Continental Plate. Since 1994 the continent has moved one and a half metres (5 feet) north crashing into the Pacific Plate which is heading west at a mind blowing 11 centimetres (4.3 inches) a year.
Since GPS is keyed to latitude and longitude, this continental drift has introduced inaccuracies well in excess of a metre in global positioning instruments. Recalibration will be based on Australia’s expected location in 2020.
