One of the most important problems in earthquake engineering is to predict the intensity of future earthquakes from the past available earthquake recording data, as a precise earthquake forecasting is difficult at present. The expectancy of maximum earthquake motions in a certain place may be defined by the seismic activity on the base rock and the ground characteristics. In order to clarify this more reliably, it is necessary to investigate the regional distribution or variation of seismic activity and the characteristics of soil-layers. This paper deals with the expected values of the intensity of future earthquakes on the base rock by introducing Gumble's Theory of Extremes (Gumbel's Second Asymtotic Distribution) and the regional distribution of the characteristics of soil-layers in the period range of 2.O to 6.0 sec., using the seismic data of strong motion seismographs published by Japan Meteorological Agency. The former indicates quantitatively the regional distribution of earthquake motions reflecting the seismic activity on the base rock in and around Japan, the latter indicates the soil characteristics reflecting the deep ground structure of fairly large area. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
