Seismic images of crustal variations beneath the East Anatolian Plateau (Turkey) from teleseismic receiver functions
Özacar, Atilla Arda; Gilbert, Hersh; Beck, Susan L. (2010-12-01)
We used teleseismic P-wave receiver functions recorded by the Eastern Turkey Seismic Experiment to determine the crustal structure across an active continent-continent collision zone. Moho depth and V-p/V-s variations in the region are mapped by incorporating crustal multiples and later two-dimsional (2-D) seismic profiles are produced using a common conversion point technique with our crustal V-p/V-s estimates. Moho depths do not correlate with surface topography and reveal a relatively thin crust consiste...

Seismic hazard assessment for the North Anatolian and San Andreas faults based on random field models
Akkaya, AD; Yücemen, Mehmet Semih (1999-12-15)
The North Anatolian fault (NAF), located in northern Turkey and California's San Andreas fault (SAF) show remarkable similarities. A random field model, developed by the authors (Akkaya & Yucemen 1996) is utilized to compare the seismicity characteristics of the two faults on a statistical basis. The seismic hazard model is based on the level-crossing theory of random fields and considers the space-time correlations simultaneously and explicitly through the use of spatial and temporal scales of fluctuation....
Seismic attenuation tomography of the Sn phase beneath the Turkish-Iranian Plateau and the Zagros mountain belt

The Turkish-Iranian Plateau and the Zagros highlands are among the most prominent physiographic features in the Middle East and were formed as a result of continental collision between the Arabian and Eurasian plates. To better understand the nature of the lithospheric mantle and the origin of the observed seismic anomalies in this region, we investigated seismic attenuation of the uppermost mantle by detailed measurements of the quality factor of the Sn seismic phase (Sn Q). To that end, we collected a lar...
Seismic evidence of shallow gas in the sediment on the shelf off Trabzon, southeastern Black Sea
Okyar, M; Ediger, V (1999-04-01)
High-resolution seismic surveys carried out on the shelf off Trabzon (southeastern Black Sea) show that the sub-bottom stratigraphy consists of two main depositional sequences (A and B) one of which contains zones of acoustic turbidity. Of these, the upper depositional sequence (A) is thought to comprise Holocene sediments, while the lower depositional sequence (B) is interpreted as approximating to the Pleistocene. The boundary between these sequences is defined by a reflector (R), which is interpreted as ...
