The purpose of this paper is to compare the evaluations between seismic diagnoses, and to explain relationship between the evaluations and earthquake damage levels. First, 111 conventional wooden houses damaged by the Hyogoken-Nanbu Earthquake are diagnosed. Therefore, earthquake damage levels of these houses are judged. Major findings are as follows. Even with the same house, the evaluation may differ widely according to the seismic diagnosis. As the estimation of earthquake resisting elements become more delicate, the correlation of the evaluation with the earthquake damage level become higher, in other words, the reliability of the evaluation become higher. On the other hand, it is difficult to specify the damage level from the evaluation, because the standard deviation of the evaluation is not small.
