Precursory seismic quiescence in the Mudurnu Valley, North Anatolian fault zone, Turkey

A Systematic Test on Precursory Seismic Quiescence in Armenia

A systematic test on seismic quiescence occurring before large earthquakes is conducted. For a fixed geographical location, the degree of clustering in space and time is analysed and the results are tested against randomized earthquake catalogs. A gridding technique allows to investigate the entire spatial volume covered by a certain earthquake catalog. The result is a significance K( x, t) for...

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...

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...

A Fault Slip Transient on the North Anatolian Fault

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...
