Abstract:

On 2017 and 2018 four strong/moderate earthquakes occurred at shallow focal depths in the East Mediterranean. They share a common characteristic, which is that a large part of the induced ground deformation is offshore, thus a part of the deformation footprint is missing. Assuming that the deformation source of an earthquake can be modelled by the slip on a rectangular fault buried in an elastic and homogenous halfspace and through inversion on GNSS and multitrack InSAR (with different weight in each case) we modelled the deformation sources and calculated their fault parameters. Seismological data as well as the geological context exploited to assist the initialization of some parameters in the inversion and
validate the results. This study demonstrate the efficiency and the contribution of the space geodesy to the seismology, even in such adverse conditions.
