The Taipei basin is a triangle-shaped formation.The ground surface ofthe basin is almost flat,but tilting gently to the northwest.The geologicalstructure inside the basin consists of Quaternary layers above the Tertiarybase rock.A dense strong motion observation network has operated in theTaipei area since 1991,as part of the Taiwan Strong Motion InstrumentationProgram(TSMIP).Characteristics of site effects in the Taipei basinare studied using the data recorded by this observation network.In thisstudy,the method of amplitude spectrum ratio is used to analyze site effectsin the Taipei basin.This analysis clearly shows that the spectral ratiocontours at low frequency bands(0.2-1Hz)correlate with the structuresof the Tertiary basement shape and the top soft soil layer.For the higherfrequency band(1-3Hz),the main amplification effects occur near thenorth,east,and south basin edges.This shows that the edge effect found inthe Kobe earthquake could possibly occur in this area.Dominant frequenciesin the Taipei basin area are also given in this study.This will benefitthe microzonation work for future earthquake hazard mitigation in theTaipei basin.
