The determination of relations between statistical seismicity data and geodetic strain analysis, and the analysis of seismic hazard in southwest Anatolia

Geomatics Natural Hazards and Risk (2014)

Engīn Gülal İbrahim Tiryakioğlu Ümit Yalçın Kalyoncuoğlu Saffet Erdoğan M. Nuri Dolmaz

This study aims the relations between seismicity data and strain analysis based on geodetic space techniques in order to define the seismicity hazard of the southwest Anatolian region of Turkey. This region has complex tectonic formations and requires sophisticated techniques and approaches to investigate seismic activities. In this study, global navigation satellite system (GNSS) observations were used to determine the velocity field of the region. The strain rates of the region were obtained from the evaluation of this velocity field. In addition, seismicity b parameters of the region were calculated from the analysis of seismicity data. Furthermore, the seismicity data and the geodetic strain rates obtained from the GNSS observations were combined to show the statistical correlation. This correlation was interpreted to define the seismicity. According to the results derived from the correlation analysis, the geodetic strain analysis and seismicity data were highly and inversely correlated (r = −0.96). After the determination of the correlation, the seismic hazard data of the region was added to the analysis. This process shows that seismic hazards are highly and negatively correlated to seismicity data (r = −0.90), even though they are highly but positively correlated to geodetic strain analysis (r = 0.88).

3D MODELING OF A BAZAAR IN ANCIENT HARRAN CITY USING LASER SCANNING TECHNIQUE

The international archives of the photogrammetry, remote sensing and spatial information sciences/International archives of the photogrammetry, remote sensing and spatial information sciences (2017)

Halil İ̇brahim ŞENOL Saffet Erdoğan Mehmet Önal Mustafa Ulukavak Abdulkadir Memduhoğlu

Abstract. Turkey is a rich country in historical monuments. In the district of Harran, Şanlıurfa province, the work was done, an ancient city and many other ruins beside the world's first university can be found. Considering the climate and sensitive structure of the studied region 3D modeling is a suitable technique. By means of such works reconstruction, that can show us the former state of the region will be enabled at a later point of time. In case the historical site would be destroyed in any way, it will be useful for recording the work as a visual and digital resource. Then, when the work has to be restored, the data can be used as a base and realistic restoration projects could be carried out.

GPS Velocity and Strain Rate Fields in Southwest Anatolia from Repeated GPS Measurements

Sensors (2009)

Saffet Erdoğan Muhammed Şahin İbrahim Tiryakioğlu Engīn Gülal Ali Kazım Telli

Southwestern Turkey is a tectonically active area. To determine kinematics and strain distribution in this region, a GPS network of sixteen stations was established. We have used GPS velocity field data for southwest Anatolia from continuous measurements covering the period 2003 to 2006 to estimate current crustal deformation of this tectonically active region. GPS data were processed using GAMIT/GLOBK software and velocity and strain rate fields were estimated in the study area. The measurements showed velocities of 15-30 mm/yr toward the southwest and strain values up to 0.28-8.23×10(-8). Results showed that extension has been determined in the Burdur-Isparta region. In this study, all of strain data reveal an extensional neotectonic regime through the northeast edge of the Isparta Angle despite the previously reported compressional neotectonic regime. Meanwhile, results showed some small differences relatively with the 2006 model of Reilinger et al. As a result, active tectonic movements, in agreement with earthquake fault plane solutions showed important activity.

Applications of global positioning system (GPS) in geodynamics: with three examples from turkey

Hakan Yavaşoğlu Ergin Tarı Murat Şahin Himmet Karaman Turan Erden

Global Positioning System (GPS) has been very useful tool for the last two decades in the area of geodynamics because or the validation of the GPS results by the Very Long Baseline Interferometry (VLBI) and Satellite Laser Ranging (SLR) observations. The modest budget requirement and the high accuracy relative positioning availability of GPS increased the use of it in determination of crustal and/or regional deformations. Since the civilian use the GPS began in 1980, the development on the receiver and antenna technology with the ease of use software packages reached to a well known state, which may be named as a revolution in the Earth Sciences among other application fields. Analysis of a GPS network can also give unknown information about the fault lines that can not be seen from the ground surface. Having information about the strain accumulation along the fault line may allow us to evaluate future probabilities of regional earthquake hazards and develop earthquake scenarios for specific faults. In this study, the use of GPS in geodynamical studies will be outlined throughout the instrumentation, the measurements, and the methods utilized. The preliminary results of three projects, sponsored by the Scientific & Technical Research Council of Turkey (TUBITAK) and Istanbul Technical University (ITU) which have been carried out in Turkey using GPS will be summarized. The projects are mainly aimed to determine the movements along the fault zones. Two of the projects have been implemented along the North Anatolian Fault Zone. (NAFZ), one is in Mid-Anatolia region, and the ther is in Western Marmara region. The third project has been carried out in the Fethiye-Burdur region. The collected GPS data were processed by the GAMIT/GLOBK software The results are represented as velocity vectors obtained using the yearly combinations of the daily measured GPS data.
