This study presents an integral approach to construct a comprehensive subsurface structure of Lanyang Plain. It is well known that geophysicists and engineers use different techniques to investigate the subsurface structure, and each of these techniques has its own advantages. Therefore, in this study, the excellent results from these two fields are selected and combined to provide a comprehensive profile of the subsurface structure of Lanyang Plain. In this study, the subsurface information on nine recording stations and digital boundary lines of Lanyang Plain based on the digital geologic map published by the Central Geological Survey are utilized to create a three dimensional surface structure of Lanyang Plain. On the other hand, data on 771 boring logs in the Ilan area are collected from many agencies. Using these two data bases, a comprehensive subsurface structure of Lanyang Plain is established by combining the subsurface data inferred from geophysicist’s investigation and the detailed boring log data close to ground surface from engineer’s endeavor. The results of this study can be utilized in the field of disaster reduction, such as the calculation of ground response subject to earthquakes using the SHAKE computer program and then the evaluation of safety of buildings in a seismic event.
