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.
