Despite most of the methods use derivatives to estimate boundaries, it is possible to apply boundary analysis using simple arithmetic operations. In this study, we present Moving Average Differences as a new and simple boundary analysis method. The method examines the smoothed areas of Bouguer anomalies by moving average filter to enhance the boundaries. We tested this method on artificial and actual Bouguer gravity anomalies and compared with commonly used boundary analysis methods.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"1 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":"130908696","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}

This study presents preliminary results of the evaluation of seismic refraction tomography (SRT), multichannel analysis of surface wave (MASW), electrical resistivity tomography (ERT) and microtremor (HVSR) data collected in from an active landslide where is located in Isiklar locality of Macka district in Trabzon province. From these data, 2D P-wave velocity and ERT sections, 1D S-wave velocity depth profile, and the values of predominant frequency and H/V amplitude of ground were obtained by using regular processes and inversion steps. Based on preliminary results, possible distribution of landslide materials in the horizontal and vertical directions was revealed and it is shown that the landslide materials with a thickness exceeding approximately 12 meters. Dominant materials of study area are composed of large and small blocky rocks and have a very complex structure. Moreover, the SRT and ERT sections show the presence of a valley-shaped structure and that the type of landslide is a combination of collapse-sliding.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"176 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":"131467671","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}

This geophysical survey aimed at: 1) the detection of abandoned underground lignite mine galleries at selected positions along subway line, 2) the mapping of geological formations and possible faults at the studied sites and 3) providing information for optimal design of tunnel path. Eleven (11) seismic tomograms of 225.3m total length and 520m total depth were generated between twenty (20) boreholes. The borehole source BIS-SH was utilized to produce highly repeatable compressional (P) waves at 2 m intervals and a hydrophone streamer consisted of 12 receivers at 1 meter intervals and a 12-channel seismograph were employed for seismic wave recording. First arrivals picking and travel time tomography were performed using SeisImager2D and ReflexW, respectively. Low velocity anomalies were found at 2 seismic sections, which probably are associated with abandoned underground lignite mine galleries or intact lignite layers. Moreover, indications for an unmapped fault presence revealed and a new tunnel path was proposed in order to avoid crossing the fault zone.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"39 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":"128813429","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}

The device is designed to record microseismic ambient noise on the basis of which to analyze the fundamental response frequency at the recording site. It is based on the three component ADXL355z acceleration sensor, featuring a 24bit ADC. The applied method for the data analysis is the H/V spectral ratio technique. We performed simultaneous recordings of ambient noise at two sites with two systems – ANA and a velocimeter GBV-316.
