Understanding the tectonic mechanism generated by the earthquakes and faults is possible only if the preseismic, coseismic and postseismic crustal deformation related to the earthquakes is determined properly. By the analysis of continuous GPS (CGPS) coordinate time series, it is possible to estimate the crustal deformation. Besides, accelerometer records at strong motion stations (SMSs) may support the CGPS-based estimates. In this study, CGPS coordinate time series were analyzed in comparison with the accelerometer records for clarifying the coseismic deformation caused by the earthquake occurred in the surrounding of Lesvos fault located in the northern part of Karaburun within the active mechanism that controls the area where the earthquakes occurred during June 2017 on the offshore Karaburun. | Turkish Journal of Earth Sciences Turkish J Earth Sci 2021 30 341-358 http earth TÜBİTAK Research Article doi yer-2008-3 12th June 2017 offshore Karaburun-Lesvos Island earthquake coseismic deformation analysis using continuous GPS and seismological data 1 2 2 3 2 Hasan YILDIZ Ayça ÇIRMIK Oya PAMUKÇU Özkan Cevdet ÖZDAĞ Tolga GÖNENÇ 4 Muzaffer KAHVECİ 1 Higher Technical School of Surveying General Directorate of Mapping Ankara Turkey 2 Department of Geophysical Engineering Faculty of Engineering Dokuz Eylül University İzmir Turkey 3 Earthquake Research and Implementation Center Dokuz Eylül University İzmir Turkey 4 Department of Surveying Engineering Faculty of Engineering and Natural Sciences Konya Technical University Konya Turkey Received Accepted Published Online Final Version Abstract Understanding the tectonic mechanism generated by the earthquakes and faults is possible only if the preseismic coseismic and postseismic crustal deformation related to the earthquakes is determined properly. By the analysis of continuous GPS CGPS coordinate time series it is possible to estimate the crustal deformation. Besides accelerometer records at strong motion stations SMSs may support the CGPS-based estimates.

The activity of this fault continued throughout June 2017 until the time when the main shock 12th June 2017 Mw occurred. We analyzed CGPS coordinate time series of AYVL and CESM and DEUG stations to determine the coseismic deformation due to the offshore Karaburun-Lesvos Island earthquake using the empirical mode decomposition
