On Earth-current observed at Kakioka Magnetic Observatory. (Part I)

[摘要] The following two phenomenon observed at Kakioka magnetic observatory from Aug. 1932 to Apr. 1933 are reported;i) Micro-pulsation and Storm of earth-currentii) Some variations of earth curr. which may be caused by earthquakes.The former points out that micro-pulsation and storm are also observed in earth-curr. as well as in earth-magnetism, showing a closed relation, even if their appraent features are so markedly different. The later shows a possible relation between earth-quake and earth-curr., but a basted opinion must be avoided. One of the most desirable method in this line is to study each record refered to those at other places and of other related phenomenon, especially of earth-magnetism.
