Sabrina's paper published

​A Tectonophysics paper entitled "Plate boundary deformation in North Iceland during 1992-2009 revealed by InSAR time-series analysis and GPS" by Sabrina Metzger and Sigurjón Jónsson is now available online.  In the paper Sabrina uses ERS-1/2 data, spanning almost two decades, to map out the deformation across the plate-boundary in northern Iceland, with a special focus on the Húsavík-Flatey transform fault and the Theistareykir and Krafla fissure swarms. The results reveal interseismic and interrifting deformation at the boundary, as well as transient deformation at Theistareykir and Krafla central volcanoes.  The InSAR data are consistent with our previous GPS results in the sense that the Húsavík-Flatey transform fault appears to accommodate about 1/3 of the transform motion in the Tjörnes Fracture Zone (the other 2/3 is likely focused on the offshore Grímsey Oblique Rift), further highlighting the seismic potential of this transform fault in North Iceland.
