Deciphering aseismic deformation along submarine fault branches below the eastern Sea of Marmara (Turkey): Insights from seismicity, strainmeter, and GNSS data

The recently observed slow transients in the Sea of Marmara are important to quantify seismic hazard and risk for greater Istanbul metropolitan region. In this study, we analyze characterize a slip event that occurred Eastern 2016. To temporal history location event, combine first time region different types geodetic data (strainmeters GNSS stations) seismicity. We propose two interpretations explain observations: either initiated on western part Armutlu fault then propagated approximately 40 km eastward, or it section fault, jumped onto perpendicular after propagating ca. 15 km. deduce these from forward modeling strain displacement data. addition, our results also suggest triggered seismicity neighboring fault. • study transient signal 2016 strainmeters, one station. use an Independent Component Analysis method remove seasonal component strainmeter recordings. model as succession tectonic deformation events.
