Crustal thickness variations and isostatic disequilibrium across the North Anatolian Fault, western Turkey

Crustal structure of the North Anatolian and East Anatolian Fault Systems from magnetotelluric data

Magnetotelluric (MT) studies can map subsurface resistivity structure and have located zones of low resistivity (high conductivity) within major strike-slip fault zones worldwide which have been interpreted as regions of elevated fluid content. This study describes MT data from the eastern part of the North Anatolian and the East Anatolian Fault Systems (NAFS and EAFS) and presents the results ...

Paleoseismic 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...

Systematic analysis of crustal anisotropy along the Karadere–Düzce branch of the North Anatolian fault

S U M M A R Y We perform a systematic analysis of crustal anisotropy along and around the Karadere–Düzce branch of the North Anatolian fault (NAF), which ruptured during the 1999 Mw 7.4 İzmit and Mw 7.1 Düzce earthquakes. A method consisting of an iterative grid search for the best shear wave splitting parameters in sliding time windows is applied to ∼22 000 measurements recorded in the 6-month...

A 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...
