چکیده
The Northern Branch of the North Anatolian Fault System controls and deforms Izmit Basin Sapanca Lake in study area. Unlike Basin, oblique normal faults with WNW–ESE trending maximum length 5 km south basin have contributed to deformation process formation Basin. fault sets mainly incline north. N-S width dextral strike-slip active was determined as 9 at 3.8 basin. Further, minimum principal stress axes (σ3) vary ranges N11°–74°E, which are caused by transtensional stresses associated faulting a different tectonic source than Besides, crust depth main strand NAFS-NB up 1112 m magnetic method. secondary were both resistivity methods 110 m. depression area between bay on northern is an integrated two origins. Thus, along faulting, has been developed asymmetric negative flower structure, where only southern boundary become fault. lazy-Z-shaped pull-apart system formed E–W releasing bend.

Viscoelastic deformation from North Anatolian Fault Zone earthquakes and the eastern Mediterranean GPS velocity field
[1] We have modeled linear viscoelastic relaxation of a uniformviscosity asthenosphere following large earthquakes in the AegeanAnatolian region during the 20th century to evaluate whether this process contributes significantly to the regional velocity field. We address in particular whether southward motion of the Aegean Sea region relative to central Anatolia (and thus extension of western Tu...
متن کاملA comparison between the Kazerun (Iran) and the North Anatolian (Turkey) fault systems in fault interaction and seismicity migration based on the spatiotemporal analysis of earthquakes
The Kazerun Fault System (KFS) is a right-lateral strike slip fault system in the middle part of the Zagros seismogenic zone in Iran. Historical and instrumental earthquake data catalogs of this fault system show good evidence of fault interactions and seismic migrations. This study provides evidence for the migration of seismicity in the middle part of the Zagros region along the segments of t...
متن کاملPaleoseismic Evidence of Characteristic Slip on the Western Segment of the North Anatolian Fault, Turkey
We have conducted a paleoseismic investigation of serial fault rupture at one site along the 110-km rupture of the North Anatolian fault that produced the Mw 7.4 earthquake of 17 August 1999. The benefit of using a recent rupture to compare serial ruptures lies in the fact that the location, magnitude, and slip vector of the most recent event are all very well documented. We wished to determine...
