	abstract = {On July 20, 2017 22:31 UTC, a strong Mw{\th}inspace}={\th}inspace}6.6 earthquake occurred at shallow depth between Kos Island (Greece) and Bodrum (Turkey). We derive a co-seismic fault model from joint inversion of geodetic data (GNSS and InSAR) assuming that the earthquake can be modelled by the slip of a rectangular fault buried in an elastic and homogeneous half-space. The GNSS observations constrain well most of the model parameters but do not permit to discriminate between south- and north-dipping planes. However, the interferograms, produced from C-band ESA Sentinel 1 data, give a clear preference to the north-dipping plane. We also map surface motion away from the satellite along the Turkish coast (from Bodrum towards the east) which reached about 17\&nbsp;cm onshore islet Karaada. The best-fit model is obtained with a 37{\textdegree} north-dipping, N283{\textdegree}E striking normal fault, in agreement with the published moment tensor solutions. The resolved slip vector is dominantly normal with a slight component of left-lateral motion (15{\textdegree}). The surface projection of the seismic fault outcrops in the G{\"o}kova ridge area, a well-developed bathymetric feature inside the western Gulf of G{\"o}kova. Our geodetic model fits the pattern of the shallow, north-dipping aftershocks obtained from rigorous relocation of all available recordings in the region (about 1120 events; relocated mainshock is at 36.955{\textdegree}N, 27.448{\textdegree}E; depth at 9.2\&nbsp;km{\th}inspace}{\textpm}{\th}inspace}0.5\&nbsp;km). The relocated aftershocks also indicate clustering at both ends of the rupture and seismicity triggering mainly towards the east and the north, within 2 weeks following the mainshock. We also analysed regional GPS data (interseismic velocities) and obtained an extension rate of 3.2\&nbsp;mm/yr across the G{\"o}kova rift, along a direction N165{\textdegree}E.},
