Abstract

The state of the Main Marmara Fault (fault segment of the North Anatolian Fault) is widely discussed, towards whether it is creeping or locked. The authors here present seafloor geodetic measurements which indicate a complete locking of the fault in the central part of the Sea of Marmara. This provides significant information for the assessment of both seismic and potential tsunami hazard to Istanbul.

Funding

The acoustic seafloor monitoring in the Sea of Marmara is a joint project of the Istanbul Technical University (Turkey) together with the University of Brest (France) and GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany). We thank C. Ham-mersley and T. Bennetts from Sonardyne for their technical support with the geodetic instruments over the years. We thank the crews and Captains of R/V Pourquoi Pas?, R/V Poseidon, R/V Yunus and Oktay 8 for their support during installation and maintenance of the network. The GeoSEA Array is funded through grant 03F0658I of the BMBF (German Federal Ministry of Education and Research). Support was provided by the bilateral ANR/TÜBITAK collaborative research project MAREGAMI (ANR-16-CE03-0010-02 and Tübitak Project 116Y371). The French geodetic array was funded by the European Union, the Brittany Region and the French government (CPER ODO); support for the cruises was provided by CNRS-INSU through the European Monitoring Seafloor Observatory programme (EMSO).
