Conductivity Anomalies in the Eastern Part of Hokkaido, Japan
Field observations of geomagnetic and geoelectric variations were made at several stations in the eastern part of Hokkaido.
From the records， geomagnetic and geoelectric bay, si, ssc and similar short period variations are selected, and coefficients of preferred plain in which geomagnetic variation vectors lie, relations between geomagnetic horizontal vectors at Memambetsu Magnetic Observatory and those at the other temporary stations are studied. And at four stations，transfer functions are obtained from Fourier transforms of some isolated short events.
From model calculations of magnetic fields caused by current flowing in the deposits of Konsen Plain，it is confirmed that the deposits play an important role for the observed geomagnetic variations.
