Abstract
A questionnaire survey is carried out to investigate the distribution of seismic intensity in Osaka prefecture during the 1995 Hyogo-ken Nanbu Earthquake. The results are compared with the measured seismic intensity calculated from the observed records and the questionnaire seismic intensity resulted by other surveys in the overlapped regions. It is concluded that the questionnaire seismic intensity needs to be corrected using the observed strong motions. The reliable distribution of the seismic intensity is obtained by adding 0.8 to the questionnaire seismic intensity. The effects of source, path, and site characteristics on the seismic intensity distribution are also examined.
