Therefore, high resolution seismic reflectivity inversion (HRRI) of the seismic data has been an important step in the seismic data processing. However, when seismic data include noise, traditional damped and undumped least square inversion methods mostly lead to unreliable and low quality results. In addition, estimation of reflectivity from seismic data is generally band-limited and negatively affects impedance producing. For this reasons, in this study, I performed the HRRI with using Cauchy regularization (HRRI-CR). The method is iteratively applied to produce reflectivity with high resolution and has anti-noise ability, which leads to obtain accurate seismic acoustic impedance results. I tested the performance of the HRRI-CR method on synthetic data in obtaining the AI and showed that the method provides more accurate information about the layers when comparing the subsurface layer model with calculated impedance curves.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132812179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of the investigations performed by application of seismic reflection, there were defined local disturbances and discontinuities that point to loose, cracked zones in the shallower as well as in the deeper layers of the terrain structure of the investigated location. The seismic refraction method was used to define the variation of the Vp and Vs velocities of seismic waves down to a maximum depth of 30–50 meters. Defined with these investigations was the thickness of the surface layers composed of highly weathered and crushed rocks under the influence of external atmospheric conditions and also as a result of tectonic processes.
