While earth quakes will allow the plates to shift suddenly, all of the plates are constantly moving, the Australian plate alone is moving about 5cm per year, combined with relative shift of other plates the relative speed increases to between 7 and 10cm NNE per year, but different parts of the same plate are moving in different directions and at different rates. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
