A study of earthquake disaster prevention system of local city in cold and snowy area of Japan, in cases of Kusiro and Hachinohe cities.

1994年‘28’12‘夜发生“三陆-春贺-冲之地震”，1995年7’1‘晨发生与主震相当的最大余震。这对日本寒冷多雪地区的八野河市造成的破坏较大，在八野河市的抗震规划中没有考虑到。本课题的研究目的是为日本寒冷多雪地区的防震规划奠定基础。本文报告了对八野河市公立学校震害情况的问卷调查结果。大地震发生时，需要掌握震害特征与地基的关系，以检验一个地区的防震减灾工作。每个领域的基金会都有其独特之处。甚至地震破坏的特征也会对一个地区的特征产生影响。因此，需要对该地区部分地区的地震破坏情况进行认真的调查。1994年的三陆-哈鲁-卡-冲地震给八野河市造成了许多损失。本研究是探讨八野河市住宅破坏与次表层特性之间的关系。尤其是与地基软基的优势周期和厚度有关。最近，在雪区冬夜发生了两次大地震，一次是1993年的久路地震，另一次是1994年的三陆地震。我们调查了居民避难的细节和避难设施的管理。根据调查结果可以看出，地震的发生条件对当地政府管理人员S在避难所居民和设施中的活动有强烈的影响。

At night '28'12'1994, "Sanriku-Haruka-Oki Earthquake" occurred and at morning 7'1'1995, Maximum aftershock occurred as large as main earthquake. These damaged Hachinohe city where was in cold and snowy area in Japan heavy and were not assumed in earthquake prevention planning of Hachinohe city. This research subject is to lay the foundation of earthquake prevention planning in cold and snowy area in Japan. We report the result of questionnaire on these earthquakes damage of public schools at Hachinohe city by this paper.The relation between characteristic of the damage and foundation at the time of a big earthquake need to be got grasped to examine an earthquake disaster prevention of an area. There is a unique thing to a foundation in each area. Even the characteristics of earthquake damage receive an influence to a characteristic of an area. Accordingly, the survey of the damage by the earthquake in the part of the area needs to be carried out scrupulously. Many damage were received in Hachinohe city with the 1994 Sanriku-Haru-ka-Oki-Earthquake. This research is the one that examined the relation between residence damage and characteristic of sub surface layer of Hachinohe city. Especially, it perceived with the predominant period and the thickness of soft bed of a foundation.Recently, there were two big earthquakes in winter's night in snowy area that one was '1993 Kushiro -Oki-Earthquake" and another one was "1994 Sanriku-Haruka-Oki-Earthquake". We investigated the details of resident's refuge and managements of refuge facilities. According to the result of our investigations, it was made to be clear that the earthquake occurrence condition were strongly to affect the local government manager' s activity in refuge resident and facility.
