| Abstract: | In this paper, the characteristic features of the short period geomagnetic variations observed in the eastern part of the Kansu Province have been studied. It can be inferred that an east-west belt of high electrical conductivity exists underneath this region. With reference to geothermal and earthquake activity of the same region, the question of the origin of the conductivity belt was examined and a preliminary explanation made. . It has also been attempted to relate the conductivity anomaly with earthquakes. |
