The data of about 30, 000 borehole records centering around the Metropolitan area has been stored in the database. The data were produced at the fundamental survey for construction of various structures. Regional distribution of the ground properties such as thickness of soft ground, vibrational characteristics of ground, liquefaction potential of sand layer, etc. are grasped from the database.In addition, using the characteristics of earthquake motions in the basement and in the sedimentary layer estimated by the model constructed from the observed data at the network of strongmotions including three deep boreholes, regional distribution of the size of surface ground motions were estimated.
