Collecting Process of Earthquake Damage Information by Municipal Authorities

准确、快速地收集因地震而受损地区的相关信息，可以激活最佳市政活动，如紧急呼叫市政工作人员，疏散受灾地区的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，以利于震后城市应急系统的更新。通过对1993年钏路地震、1993年北海道南西地震和1994年北海道东邦地震中地方政府的大量受灾报告进行分析，我们发现了影响受灾信息收集速度的各种因素;例如，以地震烈度表示的地震动烈度，以人口表示的城市面积大小，可用于调查损失的劳动力数量有限，

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,
