A new systematic method to diagnose of total safety against an earthquake in household unit was developed in order to mitigate various disasters in urban area during destructive eatthquakes.Until now, many methods which check up the structural safety of dwellings in advance have been proposed. The earthquake-resistant structure dose not always promise the total safety against an earthquake for a household, because an earthquake disaster contains not only the loss of physical objects but also the loss of human lives and disturbance of activities.From this point of view, new diagnosis of total safety against earthquakes considering direct as well as indirect damages was introduced. Related items to be inquired were collected from various reports and data of past earthquakes and were composed into a questionnaire form. Contents of a queationnaire sheet and diagnostic strategy were examined and revised through a trial survey. Then, aiming at practical use a pilot test was performed choosing 720 households in Kawasaki city, Japan (whose population is about 1 million) and capability and reliability of the method was confirmed.

为减轻城市居民在破坏性地震中遭受的各种灾害，提出了一种新的系统的住宅单位抗震安全诊断方法，并提出了多种房屋结构安全预检的方法。抗震结构并不总是保证家庭在地震中的完全安全，因为地震灾害不仅包括实物的损失，还包括人的生命损失和活动的干扰。从这个角度出发，引入了考虑直接和间接破坏的地震总体安全诊断新方法。从历次地震的各种报告和数据中收集相关的调查项目，并组成调查表。通过一次试行调查，对问卷内容和诊断策略进行了检查和修订。然后，从实际应用的角度出发，在日本川崎市(人口约100万)的720户居民中进行了中试，验证了该方法的可行性和可靠性。
