[SEM19-P11] Localized variations in the geomagnetic field and their relation with tectonic activities

*Ken'ichi Yamazaki1 (1.Disaster Prevention Research Institute, Kyoto University)

Keywords:geomagnetic field, secular variation, localized anomalies, tectonic activities, principal component analysis

Localized variations in the geomagnetic field is believed to be related with tectonic activities.
I extract the local variations by means of the principal component analysis.
No obvious relation have been found between the extracted local variations in the geomagnetic field and tectonic activities.
