Analysis of TEC anomalies relation to the ۲۰۰۳ Hokkaido earthquakes greater than ۵ M

In this research, by reducing the effects of the sun on the TEC value of ۲۰۰۳ in the Hokkaido region(۴۳°N, ۱۴۴°E) and extracting its anomalies, the relationship between the TEC anomaly and earthquakes greaterthan ۵ M has been investigated. This study shows that there is a significant relationship between the observationtime of TEC anomalies before the earthquakes and the earthquakes
