The
complex tectonic setting of Costa Rica implies the necessity of a real seismic
hazard scenario characterization for lifeline facilities and the country. In
this paper, one of the conventional spectral inversion technique is applied to
strong ground motion records to separate the site effect, the source spectra
and the path effect. To assure the quality of the results, the broadband
station JTS000 of IRIS/IDA is also incorporated. Two newly developed
consistency checks were established to assure the appropriateness of the input
data using the individual site effects and Fourier synthetic spectra. The
frequency dependent quality factor
