A questionnaire focusing on finding out the acceptable damage level of ordinary citizens against earthquake hazards is carried out. One of the distinguished features of this questionnaire was to discover the acceptable level of infrastructures in comparison to private apartment buildings. It was also attempted to find out the acceptable damage rate to the structures by asking return period for damages in indirect and manipulative ways. Major findings of this study are (1) the acceptable annual rate for large earthquake damage seems to lie between 10 to -3 to -5, (2) most of the citizens consider infrastructures should be more seismic resistant than privately owed apartment buildings in concept, however if the same question is asked in more specific ways, this order can be reversed.
