  TEMPORAL VARIATIONS OF THE FRACTAL PROPERTIES OF SEISMICITY   (Site not responding. Last check: 2007-11-05)
The North Anatolian Fault Zone (NAFZ) is a seismically-active dextral strike slip fault zone which forms the northern boundary of the westward moving Anatolian plate.
In this study, we investigate the temporal variation of Dc and the Gutenberg-Richter b-value for seismicity in the western part of the NAFZ (including the northern Aegean sea) for earthquakes of Ms > 4.5 occurring in the period between 1900 and 1992.
Dextral motion on the western part of the NAFZ is clearly expressed by an abundance of physiographic and geologic features (Allen, 1969; Barka, 1992).

The NAFZ is an active right-lateral system that forms the northern boundary of the Anatolian block for a length of about 1500 km from eastern Turkey to mainland Greece [Saroglu et al., 1992] (fig.
To the east of the town of Bolu, the NAFZ is formed by a main single trace but, west of it, it starts splaying into two main strands, the Duzce/Karadere and the Mudurnu fault segments, to splay again into three major strands farther to the west (fig.
The large number of earthquakes belonging to the NAFZ testify that the present-day high strain rate is seismically accommodated and depicts this fault as one of the most active strike-slip faults worldwide [Ambraseys, 1970; Ambraseys and Finkel, 1995; Ambraseys, 2002].

Patricia Nafz, who was driving home from her job at Camp Venture in Nanuet to her home in Orange County, spotted him.
Nafz, director of a home that cares for older, developmentally disabled people, said she had often seen hikers resting in the area, which is part of the Appalachian Trail, but that this scene was different.
Nafz, a former emergency medical technician, said he had blood on his chest and a hole — off center, a little to his right — in his shirt.

 BACKGROUND
NAFZ is splayed into three branches at about 31 E and continues to the Gulf of Corinth in the northern Aegean Sea.
The NAFZ is the northern boundary of the Anatolian block, which is moving to the west as a result of the continuing northward movement of the Arabian plate towards Eurasia (Figure 1).
Dextral strike-slip faulting along the NAFZ appears to continue eastward, beyond the triple junction (41°E) with the East Anatolian Fault Zone (EAFZ), but is not as continuous as it is along the NAFZ (Jackson, 1992).

 Tom Rockwell's talk abstract   (Site not responding. Last check: 2007-11-05)
The M7.4 earthquake that struck the Izmit Bay region of Turkey on August 17 was an anticipated event that occurred on the North Anatolia fault zone (NAFZ) in northwestern Turkey.
Most of this strain accumulation is released during large earthquakes, such as in 1999, and this is simply the most recent of a sequence of large earthquakes that have sequentially ruptured over 1000 km of the NAFZ from east to west since 1939.
Based on a long and rich historical record, the 1999 earthquake appears to be a repeat of a large event in 1719, which itself was part of a sequence of large earthquakes that ruptured the western half of the NAFZ between 1719 and 1766.

The works done on the NAFZ (5, 7, 8, 9, 10, 11, 12, 16, 17, and 18) built a basic interpretation platform on the “Global New Tectonic” sight of Turkey.
The great dextral NAFZ and sinistral EAFZ strike slip faults are produced by the “compression stress and torque stress” of Arabian autochthon, driven by African Plate and the “Sea Floor Spreading” Activity of Red Sea.
The northern board of the western quadrant that controlled by NAFZ, transforms the direction of the (4) to the direction of the (6) by means of the (5) segment, shown in Figure-12.

 SEISMICITY IN TURKEY
The North Anatolian fault zone (NAFZ) is one of the World’s most important active strike-slip faults, not only because of its remarkable seismic activity between 1939 and 1967, but also its significance for the tectonics of the Eastern Mediterranean region.
The NAFZ is the northern boundary of the westward moving Anatolian block and connects the compress ional regime in the Aegean Sea region.
The age and total slip of the NAFZ are very important for the tectonic history of the Eastern Mediterranean, and for the tectonic history of the Eastern Mediterranean, and for the better understanding of the geometry, mechanism and evolution of the continental deformation in this region.

 Department of Geological Sciences -- Seminar Abstract   (Site not responding. Last check: 2007-11-05)
One region in which GPS measurements of late interseismic, coseismic, and early postseismic deformation are all available is along the North Anatolian Fault Zone (NAFZ) in central Turkey.
I will show that the late interseismic data cannot be consistent with low-viscosity upper mantle, and that aseismic creep concentrated along a vertical shear zone extending the NAFZ downward through the crust most plausibly explains the early postseismic deformation.
Taken together with the deep coseismic rupture, these data suggest that interseismic creep along the NAFZ occurs along an aseismically creeping shear zone, and that shear stresses along this feature are close to the Coulomb failure threshold.

 The Earthquake of 20 September 1999 in Taiwan - by Dr. George Pararas-Carayannis
The earthquake of November 12, 1999 occurred on the northern branch of NAFZ and broke a 60-80 km segment between Duze and Bolu.
A single vertical displacement of about 1.5 m was reported in the Bolu area but his may have been an anomaly, perhaps the result of liquefaction or some surface effect, as most of the movements along the NAFZ are primarily horizontal.
The NAFZ is a very large and well known system but there has been speculation that perhaps this latest November 12, 1999 quake occurred on a parallel branch to the major fault.

 RMS Catastrophe Models - Turkey
The NAFZ is a right lateral strike-slip type fault zone that stretches 1,500 km (930 miles) across Turkey and has been the source of eight earthquakes of magnitude 7 or greater in the last century (compared to two for the San Andreas fault in California).
Modeling the hazard potential in the Marmara Sea region is more complex and uncertain than the rest of the country, because a significant portion of the NAFZ fault structure is located beneath the Marmara Sea, inhibiting geological and geomorphological investigations.
Despite its high exposure, seismic concerns and research were not focused on the Istanbul region until the 1999 Kocaeli and Duzce earthquakes because while the NAFZ has been very active east of the Gulf of Izmit, no significant earthquake has been recorded within the Marmara Sea since 1874.

 IRIS Newsletter: Volume 1999, No. 1
The NAFZ is known as the most prominent active fault in Turkey.
Since 1939, the NAFZ has produced seven earthquakes with magnitudes (Ms) larger than 7.0.
In 1997, a study of stress changes along the fault estimated a 12% probability that within the next 30 years a major earthquake may occur in the region of the NAFZ now effected by the August 17 earthquake.

 Turkey - Underwater Signatures of the Kocaeli Earthquake of August 17, 1999
The Kocaeli Earthquake was the last one of a series of westward migrating earthquakes on the NAFZ, beginning with the 1939 Erzincan Earthquake in the eastern segment.
The NAFZ is the most prominent active fault zone (30-80 km in length) in Turkey and has been the source of numerous large earthquakes throughout history.
The NAFZ is a relatively simple, narrow, and right-lateral transform, across most of Turkey.

 BACKGROUND
Also, the temporal variations of seismicity along the west (24°-31°E) and the central (31°-41°E) part of the NAFZ are determined from fractal analysis by using the b-value and the fractal dimension of earthquake epicenters.
In particular the large change in strike at the northern apex of the NAFZ is associated with the highest correlation dimension and the lowest b value for seismicity in this century.
In the examination of the temporal characteristics of earthquake occurrence, a strong negative correlation (r=-0.85) for the central NAFZ (31°-41°E) and a weaker negative correlation (r=-0.56) for the western part of NAFZ (24°-31°E) is observed between b and D

 GSC Pacific (Sidney) - Dynamics of the North Anatolian Fault Zone: clues from modeling deformation over multiple time ...
Interseismic, coseismic, and transient postseismic deformation have all been characterized in the vicinity of the 1999 Mw = 7.5 Izmit earthquake rupture and the segment immediately to the east, which ruptured during the 1940's.
Based on analyses of coseismic and postseismic deformation from the Izmit earthquake, I conclude that early NAFZ earthquake cycle deformation occurs via aseismic creep along a vertical shear zone extending the NAFZ deep into the crust.
Interseismic velocity profiles across the 1940's rupture segment suggest that relaxation of viscoelastic upper mantle and lower crust is minimal, which is consistent with afterslip dominating the early postseismic interval.

Based on four GPS campaigns carried out biannually between 1990 and 1996, the detailed kinematic field of crustal motion is calculated.
The GPS-based deformation pattern of three sections crossing the westward prolongation of the NAFZ is compared with neotectonic data.
This belt extends from the single fault trace of the NAFZ through the Gulf of Izmit, the Marmara Sea, the Sarköy region, and the Gulf of Saros into the North Aegean Trough (NAT).

 IRIS Newsletter Volume 2000, No. 1
Tectonic escape is taking place to the west, as evidenced by the right-lateral strike-slip movement along the North Anatolian Fault Zone (NAFZ) (e.g., Reilinger et al., 1997) and left lateral movement along the EAFZ (McKenzie, 1972).
The slip along the NAFZ is approximately 2 cm/yr while the slip along the EAFZ is 1 cm/yr.
This indicates that the escaping Anatolian block is rotating counter-clockwise as shown in the figure above.

 Correlation of seismotectonic variables and GPS strain measurements in western Turkey
The region of shear coincides with the Northern Anatolian Fault Zone (NAFZ); the region of extension, with the Aegean back arc region; and the region of compression, to the Aegean subduction zone between the African and Anatolian plates.
The median b value in the region of extension is larger than those observed in the regions of shear and compression and suggests that large magnitude earthquakes are less probable in this region than along the NAFZ and Aegean subduction zone.
The relationship between D and b along the NAFZ may also be an indicator of increased seismic hazard since the positive relationship between D and b is a recent characteristic of the NAFZ observed only in the 20-year period preceding the Izmit earthquake.

Since 1984 a multidisciplinary project on earthquake prediction research is being carried out by Turkish and German scientists at the western part of the North Anatolian Fault Zone (NAFZ) in Turkey.
The project is a direct consequence of the joint efforts towards an European Programme on Earthquake Prediction Research.
It is concentrated about 150 km east of Istanbul, where the NAFZ separates into two different branches.
