The presence of anomalies in geomagnetic data is one of the oldest and most prominent earthquake precursors . In this study, we examine the geomagnetic anomalies prior to the October 25, 2018, seismic event in Greece. The geomagnetic data of 7 stations within 950 km radius of seismic event in four components were investigated. The results show that there are two anomalies prior to the event, which are shown in different component of the geomagnetic records. To make sure that he observed anomalies and seismic event were correlated, in addition to the 7 stations mentioned above, the station data were also analyzed at a station 9354 km away from the seismic event.
