Description

• (Abstract) GONAF (Geophysical borehole Observatory at the North Anatolian Fault) is a joint research venture between GFZ Helmholtz Centre for Geosciences (GFZ) and the Turkish Disaster and Emergency Presidency (AFAD) in Ankara. It is co-funded by GFZ, AFAD, the Turkish Ministry of Development, the International Scientific Drilling Program (ICDP), and the German Helmholtz Association (HGF). 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. Waveform data is available from the GEOFON data centre, under network code GF.
