被災死亡者の死因分析から

A comparative study on factors of quake death between recent two earthquakes in Japan, the great Hanshin-Awaji earthquake（1995）and the Niigata Chuetsu earthquake（2004）was performed.For the difference of their natural and social attributes, the great Hanshin-Awaji earthquake was occurred in the urban and heavily populated area and the Niigata Chuetsu earthquake was occurred in the rural and sparsely populated area, differences of their structural damages and human casualties and issues for countermeasure to mass-disaster were marked in occasional. Inhuman casualties, there was found an imperceptible difference between them. Deaths by traumaticasphyxia under the collapsed housing were main events and deaths at the place to work and／or to drop in were lesser, however they were found within both earthquakes. On suchcritical situation, without checking on the safety of family members, few staff is possible to concentrate on duty. For business continuity on mass-disaster, it is absolutely necessary to establish collecting system of confirmation of the safety of staffs’ family.
