The content of disaster and disaster prevention information at the time of a disaster changes and is updated from time to time. Therefore, some information cannot be obtained if the timing is missed. The National Research Institute for Earth Science and Disaster Resilience (NIED) started to develop a system to collect, store, organize and disseminate information of disaster prevention and disaster prevention information by visiting each website every four hours. The timing of the collection and storage of disaster information does not necessarily coincide with the timing of the collection and storage of Globally, although the Internet Archive collects website information comprehensively, it is also unable to keep up with the frequently updated disaster and disaster prevention information, and is only partially able to archive disaster and disaster prevention information.
The collection, storage, organization and dissemination of disaster and disaster prevention information at the time of a disaster is intended to create an integrated cross-sectional timeline of disaster and disaster prevention information in the future. This cross-sectional and integrated disaster information timeline also aims to provide an integrated view of all the disaster prevention and disaster-related information that tends to be scattered and lost. The timeline is designed to automate the system as much as possible so that integrated information can be transmitted in near real time.
The first step in the development of the system is to automate the collection of disaster and disaster prevention information. In the future, we plan to increase the number of sites visited (currently 139 organizations and 217 sites) to ensure that no information is missed, to improve the accuracy of the information, to research and develop a system that automatically reflects the collected information in the timeline, and to propose the dissemination of disaster and disaster prevention information on each web site.
