Ganos Fault Zone image (GFZimage)

To study the main branch of the NAFZ west of the Sea of Marmara along the Ganos fault, a 40-station local seismic network has been deployed in autumn 2017. The Ganos fault has produced a M7.4 earthquake in 1912 and is believed to be locked down to the base of the seismogenic crust. The main objectives of this network are to study fault-zone head and trapped waves as well as converted phases to image the fault at depth and to characterize the transition towards the offshore Marmara seismic section that is late in its seismic cycle based on local small-scale seismicity.
