Kushiro-oki earthquake took place on the lale evening of January 15, 1993. The magnitude of this earthquake was registered 7.8 and the focal depth was 107km close to Kushiro city. Maximum acceleration recorded on the surface soil at Kushiro branch of Japan Meteorological Agency was 711gal in NS component. Inspite of such large acceleration, structural damage done by the earthquake was not large. Most of the 53 houses destroyed were caused by slope failure. However, furnitures in houses or offices were overturned and rooms were occupied by scattering materials. Functional disruption of lifeline systems was a major factor to affect human-life. In this paper, fundamental data of Questionnaire to Kushiro-branch and Tokachi-branch of Hokkaido Architects and Structural Engineers Association were summarised to make clear the effects of local soil condition, method of construction and low winter temperature on the structural and indoor damage, lifeline damage as well as damage to human-life. Cross correlations among those Questions and other analysis results will appear elsewhere in near future.
