The current tectonics of north Iceland are characterized by max M 6--7 earthquakes in the transform zone between the northern rift zone and the Kobleinsey Ridge. The last rifting period (1975--1984) was associated with an opening of up to 9 m along the Krafla fissure swarm. This period was followed by the disappearance of microseismicity along the eastern part of Husavik--Flatey Fault, the main structure of the transform zone. A GPS network was occupied in 1995 and again in 1997 to study present-day deformation on both sides of the on-land part of HFF and around its junction with the northern rift zone. The main deformational features observed are: (1) in Tj¿rnes, the HFF is locked above the ductile/brittle boundary below which ductile creep is occurring, and (2) aseismic opening along the Theystareykir and Krafla fissure swarms and along a N120 ¿E superficial fault that marks the southern boundary of Tj¿rnes. ¿ 1999 American Geophysical Union
