Study on Real Time Disaster Information Network System

1. 实时灾害信息网络系统(1)网页方便信息收集和快速传播。在本项目中，为了同时提供多种灾害信息，我们打开了网页。每当人们想了解当前和过去的自然灾害时，它使每个人都可以参考信息。网页还包括日本自然灾害预防研究小组在过去几十年里收集的自然灾害数据库。(2)模拟灾害过程中的信息传播。结果表明，信息的时滞、信息处理的负荷和信息路径在各组织单位的集中程度对防灾活动有显著影响。防灾科研协作多区域科研人员之间的协作是提高防灾科研水平的重要关键之一。在本项目中，探讨了开展更有效、更全面的防灾研究的协作方法。日本各区域的研究人员考虑到背景条件的区域特点，相互收集和交换灾害信息，以促进讨论。

1. Real Time Disaster Information Network System(1) Web pages are convenient to gather information and spread it out quickly. In the present project, the web pages were opened in order to provide several kinds of disaster information simultaneously. It made everyone possible to refer information whenever one wants to learn something about current and past natural disaster. The web pages also include the database of natural disaster collected by the natural disaster prevention research group in Japan during the last several decades.(2) The dissemination of information during disaster was simulated. As a result, it was clarified that the time lag of information, the load of information process and the concentration degree of information path at each organization units significantly influence the disaster prevention activity.2. Collaboration of disaster prevention researchThe collaboration between researchers in several regional blocks is one of important keys to improve the disaster prevention research. In the present project, the collaboration method to conduct more effective and comprehensive research on disaster prevention was discussed. To contribute its discussion, researchers in each regional block in Japan collected and exchanged disaster information each other in consideration of regional characteristics of background conditions.
