The ionosphere and earthquake relation using total electron content (TEC) values became a hot topic especially after the 2000s due to advances in monitoring of the near-Earth space. The idea behind this relation is the investigation of the anomalies that are occurring at the TEC values before or after the earthquakes if there any. However, scientists mostly investigate the anomalies using short datasets before or after the earthquakes, varying from minutes to 3 months. Without a proper and common evaluation time range, each study arrives at its own conclusion using its own perspective. Therefore, controversial results were published. In this study, we investigate 14 selected earthquakes Mw = 7 that occurred after 2010 using the 2-h interval TEC data using global ionosphere maps datasets, which consist of a yearlong TEC data for each earthquake. The 15-day anomaly-searching algorithm is applied for the whole data in the event year to obtain the anomaly frequency during a year. In this way, the randomness probabilities of the anomalies are inspected. To double-check the results, TEC data at 0 & DEG; longitude and the geomagnetic latitude of the event location, as a benchmark, is involved in the investigation to understand whether the anomalies are global or special to earthquake locations. Results were intriguing, more than half of the investigated earthquakes have more TEC anomalies at the benchmark location than at the event location.
