A computer software for the substitutional experience of earthquake disaster developed for disaster safety personnel of local administrations

本文在总结现有震害评估方法的基础上，开发了一套计算机软件，为地方政府的灾害安全人员提供地震灾害的替代经验。本研究的目的是协助地方政府组织有效的防灾工作。在第一阶段，讨论了如何使用软件，处理哪些损坏项目，如何估计损坏，以及如何准备输入数据，我们描述了软件的概要。我们决定设计的软件，使它可以定量评估在任何给定的地震烈度在一个参考网站的城市内的损害分布。在第二阶段，开发了一个带有假设目标地区区域数据库的原型模型。该模型涉及15个项目，包括建筑物损坏，生命线（电力，水和天然气系统）的设施损坏，死亡和受伤，以及火灾。在第三阶段，开发一个特定地区的区域数据库，以长冈，新泻为例，我们实现了一个适用于城市的模型。此外，在第三阶段，我们从作为灾害应对培训系统、作为恢复过程和其他长期影响的评估系统、作为与地震仪一起工作的快速评估系统的角度，讨论了软件的未来发展方向。

Collecting existing methods for estimating earthquake damage, we developed a computer software for providing disaster safety personnel of local administrations with substitutional experience of earthquake disaster. Our design intention was to help local administrations organize effective preparedness.The study was done in three staes as follows. In the first stage, discussing how the software can bve used, which damage items are dealt with, how damage is estimated, and how input data are prepared, we described an outline of the software. We decided to design the software so that it can quantitatively evaluate damage distribution within a municipality at any given seismic intensity at a reference site. In the second stage, a prototype model with a regional database for a hypothetical target area was developed. The model dealt with 15 items including building damage, facility damage of lifelines (power, water, and gas systems), deaths and injuries, and fire breakout. In the third stage, developing a regional database for a specific area, taking Nagaoka, Niigata as an example, we realized a model applicable to the city. Also, in the third stage, we discussed future directions of the software from the view points of its improvement as a training system for disaster response, as an estimation system for restoration processes and other long-term effects, and as a rapid estimation system working with a seismometer.
