The comparison of the H-component recorded at the HLN station with the Dst and Kp index data from World Data Center (WDC) for Geomagnetism, Kyoto. The rectangle indicates to the abnormal variation of crustal origin in the H-component. It has been revealed from the DST and Kp index that there is no significant external field variation during the occurrence time of the earthquake.
