TLDR
In this article, the authors presented a synthesis of recent studies of active tectonics in the region, including inland and underwater observations, in order to have a critical appraisal of the existence of large seismic gaps in the central and eastern Marmara Sea.About:

The north anatolian fault: a new look
A. M. C. Şengör,Okan Tüysüz,Caner İmren,Mehmet Sakınç,Haluk Eyidoğan,Naci Görür,Xavier Le Pichon,Claude Rangin +7 more
TL;DR: The North Anatolian Fault (NAF) as discussed by the authors is a 1200 km-long dextral strike-slip fault zone that formed by progressive strain localization in a generally westerly widening right-lateral keirogen in northern Turkey mostly along an interface juxtaposing subduction-accretion material to its south and older and stiffer continental basements to its north.

Heightened Odds of Large Earthquakes Near Istanbul: An Interaction-Based Probability Calculation
TL;DR: The probability of strong shaking in Istanbul from the description of earthquakes on the North Anatolian fault system in the Marmara Sea during the past 500 years is calculated and the resulting catalog is tested against the frequency of damage in Istanbul during the preceding millennium.

TL;DR: The MARMARASCARPS cruise using an unmanned submersible (ROV) provides direct observations to study the fine-scale morphology and geology of those scarps, their distribution, and geometry as discussed by the authors.

Active fault database of Turkey
TL;DR: In this paper, four distinct active fault types, classified according to geochronological criteria and character, were delineated on the 1:25,000 base map of Turkey and built its database within GIS environment.

Tectonic evolution of the Marmara Sea and its surroundings
TL;DR: In this paper, the authors used the Global Positioning System slip vectors and with stratigraphic results implies that the North Anatolian Fault reached into the Marmara Sea region about 3.5 million yr ago.

Initial reference models in local earthquake tomography
TL;DR: In this article, the same inversion formalism was used to determine hypocenters and one-dimensional (1-D) velocity model parameters, including station corrections, as the first step in the 3D modeling process.

Strike-slip fault geometry in Turkey and its influence on earthquake activity
Aykut Barka,K. Kadinsky-Cade +1 more
Abstract: The geometry of Turkish strike-slip faults is reviewed, showing that fault geometry plays an important role in controlling the location of large earthquake rupture segments along the fault zones. It is found that large earthquake ruptures generally do not propagate past individual stepovers that are wider than 5 km or bends that have angles greater than about 30 degrees. It is suggested that certain geometric patterns are responsible for strain accumulation along portions of the fault zone. It is shown that fault geometry plays a role in the characteristics of earthquake behavior and that aftershocks and swarm activity are often associated with releasing areas.

Westward propagation of the North Anatolian fault into the northern Aegean: Timing and kinematics
TL;DR: In this article, the authors present new evidence for the propagation processes of the North Anatolian fault in the Dardanelles Straits region allowing them to document the timing of the deformation preceding, and the finite displacement after, the passage of the propagating tip of the fault.

Slip distribution along the North Anatolian fault associated with the large earthquakes of the period 1939 to 1967
TL;DR: In this article, the authors have compiled a record of dextral slip, which contains nearly 100 points and indicate that the amount of slip is irregularly distributed along the 1939 to 1967 rupture zone.

Active tectonics of the Eastern Mediterranean region: deduced from GPS, neotectonic and seismicity data
Aykut Barka,Robert Reilinger +1 more
TL;DR: In this paper, the main tectonic features of the Eastern Mediterranean region combining the recent information obtained from GPS measurements, seismicity and neotectonic studies are reviewed, including the internal deformation in Eastern Anatolia by conjugate strike-slip faulting and E-W trending thrusts.
