Field Work

GONAF (Geophysical borehole Observatory at the North Anatolian Fault) is a joint research venture between Helmholtz Centre Potsdam German Research Centre for Geosciences Potsdam (GFZ) and the Turkish Disaster and Emergency Presidency (AFAD) in Ankara. The aim of this project is to monitor earthquake activity at low magnitude-detection threshold in the Istanbul / eastern Sea of Marmara region where a major (M>7) earthquake is pending.
