TL;DR: In this article, the authors present and interpret GPS measurements of crustal motions for the period 1988-1997 at 189 sites extending east-west from the Caucasus mountains to the Adriatic Sea and north-south from the southern edge of the Eurasian plate to the northern edge of Africa.

TL;DR: In this article, the authors use the mapped surface slip and fault geometry to infer the transfer of stress throughout the sequence of the North Anatolian fault. But they do not consider the effects of the sudden stress changes in the Coulomb failure stress.

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.

TL;DR: In this paper, the authors present and interpret GPS measurements of crustal motions for the period 1988-1994 at 54 sites extending east-west from the Caucasus mountains of southern Russia, Georgia, and Armenia to the Aegean coast of Turkey and north-south from the southern edge of the Eurasian plate (Pontus block) to the northern edge of a platform.

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.
