what type of fault is the anatolian fault

This map shows a pair of spreading centers separated by a transform fault. Transcribed image text: Faults Identify the type of fault in the following diagrams. One plate moves right or left, rubbing against the other plate. The northward movement The East and North Anatolian faults together accommodate the westward motion of the Anatolian Plate as it is squeezed out by the ongoing collision with the Eurasian Plate. In that year more than 100 people died after a quake near the city of Bingöl. Lake Hazar lies along the East Anatolian transform … More-over,the total lateral displacement of the fault and the amount of crustal extension in the Marmara Researchers from MIT and Turkey have found evidence for both types of behavior on different segments of the North Anatolian Fault — one of the most energetic earthquake zones in the world. Normal faults create space. The North Anatolian fault (NAF) is a ?? The NE-SW trending left lateral East Anatolian transform fault (EAF), is a major plate boundary, accommodates most of the active deformation between the Arabian and Anatolian plates. Both are also boundaries near a continental margin (Black Sea and Pacific Ocean). The North Anatolian Fault is subject to scrutinous examination due to its close proximity to many of the large cities and its regular seismic activity.The fault is a dextral strike-slip fault zone along Northern Turkey and has produced 6 fatal earthquakes of M>6 in the last 20 years. Earthquake potential of the San Andreas and North Anatolian Fault Zones: A comparative look M. B. Sørensen Department of Earth Science, University of Bergen, Norway, Department of Earth Science. The North Anatolian Fault is a large transform fault in which two tectonic plates are sliding past each other. In the twentieth century, nine earthquakes of this type occurred along the North Anatolian fault, one of the most active large faults in the world. The North Anatolian Fault is one of the most energetic earthquake zones in the world. [30] The Main Marmara fault is part of the northwestward extension of the North Anatolian fault zone [Sengör, 1979]. Comparison Between San Andreas Fault and North Anatolian Fault. The NAFZ is a dextral strike-slip fault … The Anatolian transform fault system is probably the most active in the world. Indeed, they can show you the fault traces crossing mountains and agricultural fields without any kind of hesitation, which The North Anatolian fault in Turkey is a 1,400-km-long fault zone made of numerous subparallel faults that split and combine, bend and straighten, and there is reason to expect major earthquakes to occur progressively farther to the west, ever closer to Istanbul. A shallow fault-zone structure illuminated by trapped waves in the Karadere–Duzce branch of the North Anatolian Fault, western Turkey Yehuda Ben-Zion, 1Zhigang Peng, David Okaya, Leonardo Seeber,2 John G. Armbruster,2 Naside Ozer,3 Andrew J. Michael,4 Serif Baris5 and Mustafa Aktar5 Transform faults are plate boundary faults, and are tens to hundreds of kilometers long. ?1500 km long, arcuate, dextral strike-slip fault zone in northern Turkey that extends from the Karliova triple junction to the Aegean Sea. Hazardous Living: Collision forces behind devastating Turkey quake. 1. along the North Anatolian Fault zone. Faults consist of two rock blocks that displace each other during an earthquake or regular tectonic movement. Patterns of damage and aftershock from that earthquake indicate a magnitude Ms = 7.3, similar to that of the 17 August 1999 earthquake [Ambraseys, 2001]. The North Anatolian Fault (NAF) (Kuzey Anadolu Fay Hattı) is an active right-lateral strike-slip fault in northern Anatolia which runs along the transform boundary between the Eurasian Plate and the Anatolian Plate.wikipedia 80Related Articles The East Anatolian Fault (Turkish: Doğu Anadolu Fay Hattı) is a major strike-slip fault zone in eastern Turkey. It forms the northern boundary of the westward moving Anatolian Plate. Different phases of the earthquake cycle captured by seismicity along the North Anatolian Fault Fatih Bulut1 1AFAM Disaster Research Center, Istanbul Aydın University, Istanbul, Turkey Abstract The North Anatolian Fault has accommodated three major earthquakes during the last 15years. The North Anatolian Fault Zone (NAFZ) is one of the best-known dextral strike-slip faults in the world because of its remarkable seismic activity, extremely well developed surface expression and importance for the tectonics of eastern Mediterranean region. nental transform faults such as the San Andreas Fault in California, the Dead Sea Transform fault in the Middle East, or the North Anatolian Fault Zone in Turkey (referred to as NAFZ hereafter) tend to produce earthquakes with magnitudes M typically not exceeding ~8, releasing ~30 times less seismic energy compared to the recent mega-thrust Beyond the spreading centers, the fault is not active because both sides move in the same direction. by Megan Sever. San Andreas Fault. In San Andreas Fault …Fault represents the transform (strike-slip) boundary between two major plates of the Earth’s crust: the Northern Pacific to the south and west and the North American to the north and east. However, relationship between EAF and DSF is still under discussion. A few miles away beneath the Marmara Sea, the North Anatolian fault line is stirring, virtually certain to rupture within a generation at the latest and bring much of Istanbul tumbling down. Draw arrows on the fault planes to show relative movement directions and label the hanging wall (HW) and footwall (FW) blocks for each fault with a hanging and footwall Draw an appropriate fault symbol (see Figure 6.10) on the map-view part of each diagram Block 1 38. Both the San Andreas and Anatolian Faults are strike-slip. The North Anatolian Fault likely ruptured through Izmit Gulf during the 10 July 1894 earthquake, and much of the accumulated static stress must have been relieved at that time. It separates the Eurasian plate from the Anatolian plate in northern Turkey. The fault, similar in scale to California’s San Andreas Fault, stretches for about 745 miles across northern Turkey and into the Aegean Sea. Since 1939, the North Anatolian fault zone has been affected by a westward propagating series of large dextral earthquakes that ruptured a total length of about 1000 km between 40°E and 29°E [Barka, 1996, 1999]. Two blocks of crust pull apart, stretching the crust into a … The difference in the relative motions of the two plates is manifest in the left lateral motion along the fault. One block is called the hanging wall, and the other is the footwall. Since 2003, however, activity has shifted to the east Anatolian fault. Turkey is set on a minor tectonic plate which is being squeezed westwards as the … Fault slip is sinistral, opposite of the apparent dextral offset of the ridges. Thursday, January 5, 2012. Although the fault zone has substantially failed during the last century, it did not completely fail in NW The North Anatolian transform fault is a morphologically distinct and seismically active strike-slip fault which extends for about 1200 km from Karliova to the Gulf of Saros along the Black Sea mountains of N. Anatolia. The North Anatolian Fault is about 1300km long running along the entire length of northern Turkey, … Parts of a Fault. 2. Understanding the parts of a fault can help you identify what type of fault you’re seeing. Well-known terrestrial examples include the San Andreas Fault, which, during the San Francisco earthquake of 1906, had a maximum movement of 6 metres (20 feet), and the Anatolian Fault, which, during the Ä°zmit earthquake of 1999, moved more than 2.5 metres (8.1 feet). This fault was discovered and described by Ketin ( The fault runs along the boundary between the Eurasian plate and the smaller Anatolian plate but movement in the area is controlled by collision of the larger Arabian plate to the south and the Eurasian plate to the north. The different styles of faulting can also combine in a single event, with one fault moving in both a vertical and strike-slip motion during an earthquake. All faults are related to the movement of Earth's tectonic plates. The biggest faults mark the boundary between two plates. However, the efficiency of the transfer of the North Anatolian fault lateral motion across the extensional Mar-mara basin is not clear over the long term. Some of the most destructive earthquakes in history have been caused by movement along this fault. However, the age and offset values are significantly different for each fault zone. It is an intracontinentalright-lateralstrike^sliptransform fault (Ketin, 1948) extending V1500 km across northern Turkey and marking the boundary be-tween the Anatolian and Eurasian plates (Fig. The North Anatolian Fault (NAF) (Turkish: Kuzey Anadolu Fay Hattı) is an active right … The North Anatolian Fault (NAF) is analogous to the San Andreas Fault (SAF) in California in some ways, with the two continental transforms sharing similar slip rates, total fault length and straightness relative to their poles of rotation (Stein et al. 1997). asked Aug 14, 2019 in Environmental & Atmospheric Sciences by Oldcrow. The North Anatolian Fault (NAF), one of the most significant neotectonic elements of Turkey, is a c. 1600 km long right-lateral system emplaced into the North Anatolian Shear Zone (NASZ; Şengör et al. The San Andreas Fault - IX. The most active and earthquake prone fault system in Turkey and the source of the 1999 magnitude 7.4 earthquake that killed nearly 18,00 people in the city of Izmit. The fault is a transform fault with the … In this paper, we present geometry of the … The North Anatolian Fault (NAF) (Turkish: Kuzey Anadolu Fay Hattı) is an active right-lateral strike-slip fault in northern Anatolia, and is the transform boundary between the Eurasian Plate and the Anatolian Plate. It is smilar is size to the San Andreas Fault. It marks the boundary between the Eurasian and Anatolian tectonic plates, which move relative to each other at a speed of around 2 cm per year. lar fault length at the eastern junction between the two branches (Mudurnu in 1967). The North Anatolian Fault (NAF) is a 1200-km-long dextral strike-slip fault zone that formed by progressive strain localization in a generally westerly widening right-lateral keirogen in northern Turkey mostly along an interface juxtaposing subduction-accretion material to its south and older and stiffer continental basements to its north. According to newspaper accounts, ground movement in both cases was roughly the same type. We discuss the subsurface structure of the Karadere-Duzce branch of the North Anatolian Fault based on analysis of a large seismic data set recorded by a local PASSCAL network in the 6 months following the Mw = 7.4 1999 Izmit earthquake. The earthquake of January 9, 1857, in southern California apparently was about the same magnitude as the San Francisco earthquake of 1906. 2004). Istanbul has one of the highest seismic vulnerabilities in the world due to its proximity to the North Anatolian Fault. We sampled syntectonic calcite from polished fault surfaces with horizontal slickenlines … The San Andreas Fault in California and the Anatolian Fault in Turkey are two well-known examples of this type of fault. 1A; Ketin, 1969; SAengo«r et al., 1985; Barka, 1992; SAarog›lu, 1988). It is connected to the Dead Sea transform fault (DSF) at the southwestern continuation. Strike-slip deformation of the NAFZ marks the onset of tectonic escape of the Anatolian block westwards and is therefore a key player in tectonic reconstructions. Strike-Slip Fault Along a strike-slip fault, the rock planes move mostly horizontally (laterally or sideways.) It forms the transform type tectonic boundary between the Anatolian Plate and the northward-moving Arabian Plate. In Turkey, "Deprem" and "Fay" are the names for earthquake and fault respectively, and these two terms are well known by the Anatolian shepherds and countrymen. The North Anatolian fault, which caused destructive earthquakes in Turkey in 1999, is comparable to the San Andreas fault in California. The new quake did not occur on the North Anatolian Fault. Fault lines vary significantly in their lengths and widths, and can be as thin as a hair, barely visible to the naked eye, or can be hundreds of miles long and even visible from outer space, such as in the cases of the Anatolian Fault in Turkey and the San Andreas Fault in the U.S. state of California. Earthquakes Along the Fault. This region is perhaps most well known for the North Anatolian Fault; the east-west striking continental transform fault situated in northern Turkey, which produces persistent earthquake activity along the fault. The North Anatolian Fault breaks into a complicated network of fault branches under the Marmara Sea, where it passes just 20 kilometers south of Istanbul.
