Abstract eng:
After the destructive Bam earthquake of December 26, 2003 (Mw = 6.6), the present survey was conducted about two months after the earthquake as a part of damage investigation by Japan Society of Civil Engineers (JSCE) earthquake damage investigation team. Questionnaire survey developed by Ohta has long and widely been used in Japan and has been conducted for recent major earthquakes in Japan to get the detailed distributions of seismic intensities. The questionnaire is to inquire how objectives around people have been shaking and how people feel during earthquake. In this paper, based on the survey carried out at nearly 20 locations by collecting some 100 questionnaires through direct interview with residents in Bam city, earthquake intensities in JMA (Japan Meteorological Agency) scale are determined and discussed through statistical analysis of the questionnaires at the locations. Findings clarify that the method though developed in Japan on the basis of its lifestyle arose somehow in the questions has promising results in Iran as well in spite of lifestyle difference between them.
