 note = {On seismic motion in the Nagano-basin, simulations were tried. Eigen value problems were solved by three-dimensioal finite element method. Underground structures were available from the existing data of explosion seismic observation of Nagano area. The models used in the analysis were 1 km deep and 20 km long, and were wide from 2 km to 10 km. The frequency of the 1-st mode calculated by the simulations and that of the amprification spectrum caluculated by the theory of multiple refrection had conciderable agreement. Using slip conditions at the boudary, where the existense of faults had been confirmed, the directivity of low frequency component of seismic motion in the Nagano-basin may be represented by the simulations., application},
