Scheiber-Enslin et al. (2011) present GPS derived horizontal velocity field in southern Iceland covering the period 1994–2006, new InSAR analyses for the periods 1993–2000 and 2003–2007.

The authors results indicate a decrease in spreading rate from northeast (15 mm yr−1) to southwest (9 mm yr−1) across the Torfajökull caldera and the intersection of the South Iceland Seismic Zone and EVZ, consistent with the propagating ridge model.
