A couple of earthquakes of M 5.4 and 5.3 occurred at 18:18 and 18:40, December 7, 1990 in the central part of the Higashi-Kubiki Hills, southern Niigata Prefecture and followed by considerable number of earthquakes for 2 months. Daily frequency of the earthquakes observed by 3 seismograms stationed in the mountains and a map of epicenters obtained are described. Many epicenters of the after shocks are distributed in a westerly area 5 to 10 km away from the main shocks. Since 1962, several earthquakes associated with strong explosive sounds have been recognized by inhabitants and suggest the area is marked by repeated shallow earthquake activities.
