Gülbahçe Fault Zone (GFZ) is a significant tectonic structure and seismic source for İzmir city and its surroundings. The major earthquakes occurred at the surroundings of GFZ are 2005 Seferihisar, 2020 Samos Island-Aegean Sea and 2021 Seferihisar earthquakes. In this study, the crustal thinning and tectonic stress distribution of GFZ and its surroundings were analyzed by using the new gravity and magnetic data. The correspondence analysis was applied by appraising together the magnetic and free-air anomaly data. Moreover, the average density of the subsurface structure was calculated by applying the Parasnis method. The deviatoric stress calculation was executed and the change of the physical properties that controls the gravity and magnetic anomaly of the crustal structure of the GFZ and its surroundings from north to south was investigated. Therefore, the average density values, which were obtained from gravity anomalies, were computed as 2.59 gr / cm 3 in the north of the study region and it decreased to 2.06, 1.8 and 1.49 gr / cm 3 towards to the south. The free-air gravity anomaly values were between 0-70 mGal and the magnetic anomalies were between -450-150 nT. The deviatoric stress

Tectonic forces formed in the continental crust, cause permanent changes in stress, compression and deformation. The amplitudes of earthquake waves vary with the stress / strain distribution in the crust. In this study, the change of stress / strain and regional absorption coefficient, which is effective in tectonic forces caused by elastic deformation energy accumulating in the brittle crust over time, was investigated. The study area is the middle part of the North Anatolian Fault Zone and the area formed by Ezinepazarı fault zone and Merzifon fault zone. In this area, Coulomb stress analysis was carried out by using the focal mechanism solution values of the earthquake that occurred in Yoldere Erbaa, Tokat on October 9, 2015 (ML = 5.1). In order to examine the deformation caused by this earthquake in and around the study area, Global Navigation Satellite System (GNSS) data were evaluated and the velocities of these stations were calculated using GNSS data of these stations for the years 2013 2014 2015 2016. Also, regional absorption coefficients were determined by using earthquake data. As a result, Coulomb stress analysis results, velocity values distribution obtained from GNSS data and absorption findings obtained from seismological study were evaluated together.

构造力在大陆地壳中形成，引起应力、压缩和变形的永久性变化。地震波的振幅随地壳中的应力/应变分布而变化。在这项研究中，研究了应力/应变和区域吸收系数的变化，这在脆性地壳中弹性变形能量积累引起的构造力中是有效的。研究区位于北安那托利亚断层带的中部，由Ezinepazarı断层带和Merzifon断层带组成。在该区域，利用2015年10月9日发生在托卡特州约尔德-埃尔巴的地震（ML=5.1）的震源机制解数值进行了库仑应力分析，评估了全球导航卫星系统（GNSS）数据，并使用这些台站2013年、2014年、2015年、2016年的GNSS数据计算了这些台站的速度。此外，还利用地震资料确定了区域吸收系数。结果，库仑应力分析结果、从GNSS数据中获得的速度值分布和从地震学研究中获得的吸收结果被一起评估。地址：Çırmık，A.，Aydın，U.，PamukçU，O.A.，Doğru，f.2022。Amasya-Tokat城市之间的北安那托利亚断层带应力分布分析。矿产研究与勘探公报xxx，x-x。DOI：https://doi.org/10.19111/bulletinofmre.1022323*Başvurulacak yazar:AyçaÇIRMIK，ayca.cirmik@deu.edu.trMaden Tetkik ve Arama Dergisihttp://dergi.mta.gov.trMTA Dergisi（2022）xxx:xx

This paper presents and analyzes results from a Finite Difference Modeling (FDM), processing, and imaging study of a Walkaway Vertical Seismic Profiling (WVSP) survey, and discusses how the images from WVSP enhance those from the surface seismic data. It is shown that the results from the WVSP integrate well with the image from the surface seismic performed in the same line. For the study, a seismic model with vertically and horizontally varying velocities was built and a WVSP data set was generated. The surface seismic had difficulty showing clear images from the layers with steep dips and near vertical displacements on the model due to the lack of ray coverage. The study demonstrates that the WVSP geometry can record reflections from near vertical layers facing the borehole, which help with imaging the parts of the subsurface structure which were missing in the surface seismic. With the proper combination of the images from the WVSP and the surface seismic, a more complete image profile of the subsurface can be constructed around the borehole. However, while contributing to surface seismic, it is also seen that the WVSP introduces more migration artifacts related to source interval distance and interbed multiples than the surface seismic data.
