Antarctica plate motion
We have analysed GPS measurements of site motion from fifty sites in the Antarctica, including the one set up by us at Maitri. The Maitri site exhibits a predominantly northward velocity of ~8 mm/year. Elsewhere on the Antarctica plate the site velocity estimates vary from 4 to 20 mm/year and exhibi...

We have analysed GPS measurements of site motion from fifty sites in the Antarctica, including the one set up by us at Maitri. The Maitri site exhibits a predominantly northward velocity of ~8 mm/year. Elsewhere on the Antarctica plate the site velocity estimates vary from 4 to 20 mm/year and exhibit spectacular rotation of the atlantic plate. The estimated pole of the Antarctica plate is located on the plate itself and thus the plate, surrounded by mostly the divergent plate margins, appear to spin along this pole. Large seasonal variations are seen in displacement time series from sites which are located closer to the pole. |
