Understand this. Not just isolated islands moved. The entire tectonic plate
in the area of the quake subsumed and everything on this plate moved along
with the plate. If the tectonic plate moved three meters then Australia
moved three meters provided the whole of Australia is on that plate.

Pate tectonics are not hard to understand. Since Pangea plates have moved.
Over the millennia Pangea broke up into the continents we see today which are
pretty evenly spaced around the globe.

I heard that the island of Sumatra has moved 35 meter.

Is or was there any anomalies in GPS positioning on the "Australian
Plate"?
Is it regulated by the satellites ?
As far as I can guess, a datum change would be necessary ?

Does anybody know any reliable sources for answers to these questions ?
