In this report, discussed were the methods and data of earthquake damage prediction in Tohoku urban areas, by which the local characteristics of each area could be reflected in the damage estimation. Five cities were considered for case studies, i. e., Sendai city in Miyagi pref., Hachinohe city in Aomori pref., Koriyama city in Hukushima pref., Akita city and Honjyo city in Akita pref..Deep ground structure in Sendai was investigated using information on microtremors, wave velocities in ground and difference in gravity (Motosaka). Using the ground model determined, prediction of ground motion intensity distribution was made for the 1978 Miyagiken-oki earthquake and for the anticipated Rifu-Nagamachi fault earthquake (Motosaka). Ground structure in Hachinohe city was investigated using microtremor data and records of earthquake measurement. (Sakajiri and Moro).Collection and analysis of data on the earthquake resistance capacity (Is value) of actual buildings in Tohoku urban areas were … More made (Shibata). Investigation on the effect of seismic retrofit of an actual RC building was made both by diagnosis calculation and by microtremor test. Prediction of ground motion intensity for 1983 Nihonkai-chubu earthquake and anticipated Akita-oki earthquake was made and maps of lifeline network were overlaid to the ground intensity map by GIS to be used for the damage prediction of lifelines. (Nogoshi). Three-dimensional vibration of a long building with slab deformation was investigated (Kurata). Investigation on the earthquake resistant capacity of wooden houses was made in Honjyo city and data were obtained on the distribution of construction age, soil condition, estimated resistance capacity (Kobayashi).Investigation on the local earthquake risk in Miyagiken-oki was made based on the report of Earthquake Investigation Committee of the Japanese Government. Probability models of earthquake occurrence in Miyagiken-oki were discussed using renewal process. Various probability models for the time interval of large earthquakes were investigated (Shibata).Analysis on the results of questionnaire on the consciousness of Sendai citizens to the earthquake disaster and its prevention was made and problems were pointed out in considering the seismic safety of regional areas taking account of local characteristics such as soil conditions, seismic resistance levels of buildings, etc. (Motosaka). Questionnaires on the consciousness to earthquake were conducted three times after 1983 Nihonkai-Chubu earthquake and the results were investigated from the viewpoint of preparedness for earthquake disaster (Nogoshi). Study on the present situation (buildings and sites) of heavily damaged areas in 1978 Miyagiken-oki earthquake was conducted (Sato). Also, in order to seek the possibility of risk management education, items on natural disaster were taken into consideration in town planning lessons at primary schools using international multi-media networks (Sato).

本报告讨论了东北地区地震震害预测的方法和数据，通过这些方法和数据可以在震害估计中反映每个地区的当地特点。以宫城县的仙台市、青森县的八仁市、户岛县的郡山市、秋田市和秋田县的本代市五个城市为例，利用微震、地面波速和重力差等信息对仙台市的深部地面结构进行了研究。利用确定的地面模型，对1978年宫根县地震和预期的日府-长町断层地震（元坂）的地震动强度分布进行了预测。利用微震资料和地震测量记录对哈钦河市的地面结构进行了研究。（坂尻茂郎）收集和分析了东北城市地区实际建筑的抗震能力（Is值）的数据…More made （Shibata）。通过诊断计算和微震试验对某实际钢筋混凝土建筑的抗震加固效果进行了研究。制作了1983年日本海中部地震和秋田崎地震的地震动烈度预测图，并利用GIS将生命线网图叠加到地震动烈度图上，用于预测生命线的破坏情况。(Nogoshi)。研究了具有板变形的长建筑物的三维振动（Kurata）。对本州市木结构房屋的抗震能力进行了调查，得到了建筑年龄、土壤条件、预估抗震能力（Kobayashi）的分布数据。根据日本政府地震调查委员会的报告，对宫根县当地地震风险进行了调查。利用更新过程讨论了宫崎县地震发生的概率模型。研究了大地震时间间隔的各种概率模型（Shibata）。对仙台市市民对地震灾害及其预防意识的问卷调查结果进行了分析，指出了考虑到当地的特点，如土壤条件、建筑物的抗震水平等，在考虑区域地震安全时存在的问题（Motosaka）。1983年日本海中部地震后，对地震意识进行了三次问卷调查，并从地震灾害防范的角度对调查结果进行了调查。对1978年宫根县地震重灾区的现状（建筑物和遗址）进行了研究（佐藤）。此外，为了寻求风险管理教育的可能性，在使用国际多媒体网络的小学城市规划课程中考虑了自然灾害的项目（Sato）。少
