This volcano erupted in a farm-land and further developed a lava dome (Spine) in the central part. It is a Pelee-type one, and its developing process was clearly observed for the whole period. Some remarkable earthquake swarms occurred during the volcanic activity, and the major ones among them were recorded by seismographs even at a station about 800 km apart from the volcano. The author investigated the relations between the occurrence of earthquakes and the formation of Showa-Shinzan and tried to find some clues to the volcanic mechanism. In this first paper, after an investigation of the characteristics of earthquake swarms recorded on the seismographs in Muroran, Mori and Sapporo (epicentral distance : 25-69 km) and the relation of the volcanic activity therewith, some interesting results were obtained : 1) Daily earthquake frequency diagram for the whole period of twenty three months were prepared for the first time. 2) These earthquakes were clearly divided into the following three stages : ( i ) Pre-volcanic stage : In this stage there was no eruption, and remarkable earthquakes occurred around Volcano Usu frequently.
