Two felt earthquakes of magnitude about 4 with rumbling of the earth, occurred at 02h46m and 03h20m (J.S.T.) Aug. 13, 1969 in the northern parts of Kanuma city, Tochigi Prefecture. To explain the cause and feature of the felt shocks and earthquake sounds which continued from that time, a temporary micro-seismic observation was carried out at Furumine Shrine, Kobugahara, Tochigi Prefecture about 15 km west of the epicenters, from Aug. 29 to Sept. 6 using the tripartite array net and from Sept. 6 to Oct. 6 with one component monitoring system. A block diagram and a sensitivity curve of the instrumentation used are given in Figs. 1 and 2. Tripartite stations were occupied, as shown in the map of Fig. 3, near the temporary observation room of Furumine Shrine.
