Collecting Process of Earthquake Damage Information by Municipal Authorities

准确、快速地收集地震受损地区的相关信息，可以激活最佳的市政活动，如市政工作人员的紧急呼叫，受灾地区的疏散命令和各种恢复计划。本文探讨了控制震害信息采集过程的一些因素，以期更新城市震后响应系统。我们分析了1993年钏路-冲、1993年北海道南井-冲和1994年北海道东湖-冲地震中地方政府提供的大量损失报告，发现了影响损失信息收集速度的各种因素；例如，以地震烈度为代表的地面运动严重程度，以人口为特征的城市面积大小，可用于调查损害的劳动力数量有限，

Collecting precisely and fast the relevant information in areas damaged due to an earthquake activates theoptimum municipal activities such as emergency calls for municipality staff, orders for evacuation of the affected areas and planning for various restoration. This paper discussed some factors controlling the collecting process of earthquake damage information in order to renew the municipal response system after an earthquake. As a result of analyzing a pile of damage reports by local governments in the 1993 Kushiro-Oki, the 1993 Hokkaido Nansei-Oki, and the 1994 Hokkaido Toho-Oki Earthquakes, we found various factors governing the speed of collecting damage information ; for example, ground motion severity represented by seismic intensity, the areal size of municipality characterized in terms of population, the limited number of available laborers for surveying damages,
