We here report a hazard assessment procedure with which to estimate the Uniform-Hazard-Spectra by a method of synthesizing spectra of large earthquake using spectra which is represented by a ¡-square model of small earthquake. This method is possible to take into account the fault extend, seismic directivity and randomness of location of a fault which in a seismic region. This procedure is that the seismic region is divided into small elements, and synthesizing the number of small elements which correspond to scaling law of large earthquake's area and small element's area. Results show that intensity of spectra in higher frequency than the corner-frequency is changed by randomness of rupture point in the plane of fault. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
