1. In November, 1965, observations of the Matsushiro earthquake swarm were carried out at five temporary observation sites northeast of the swarm area. These five stations are on a line as shown in Fig. 1, the relative distances being about 10km as given in Table 1. The range of epicentral distances of these sites from each shock is roughly between 15 and 55km. Observation schedule was usually from 22h 00m to 4h 00m of the next day, that is, six hours during the night. A magnetic tape recording system was used together with six vertical and two horizontal moving coil type seismometers with natural period 1 sec. The total system of recording has a flat frequency characteristic in the range 1～100c/s.
