Eastern Marmara Sea Region: In addtion to the earthquakes of the past 100 years (grey dots) here also smaller quake events (red dots) are shown as detected between 2006-2010 by a local seismic network on the Princess Islands Offshore Istanbul. Borehole based sensors deployed in the GONAF boreholes will detect even much smaller earthquakes allowing to characterize the fault zone below the Sea of Marmara with unprecedented Detail.
