Abstract

In this study, co-seismic displacements originating from Elazığ-Sivrice earthquake in the Eastern Anatolian Fault Zone (EAFZ) on 24 January 2020 were investigated. For this purpose, data of 11 CORS-TR stations in the nearby earthquake focal point were used. Receiver Independence Exchange (RINEX) observation data of 11 stations between the dates of 1-30 January 2020 (30 days) were obtained from CORS-TR servers and analyzed. Analyzes were carried out with GAMIT/GLOBK V10.71 software and coordinate time series were created from daily solutions. Co-seismic displacement caused by earthquake was revealed by coordinate time series and total displacements (co-seismic) were calculated by coordinate differences between the before and after the earthquake. According to the results, an earthquake-induced motion of 20-60 mm was detected at the GNSS stations located in the nearby of earthquake epicenter. In addition, vertical movement was not detected at any of the 11 CORS-TR GNSS station.
