Providing information to emergency responders and citizens is one of the most critical aspects during bushfire events. In many cases ground-based infrastructure might be malfunctioning or destroyed and satellite communication might appear the only option. This paper concentrates on the use of the QZSS satellites to provide short messages early warn...
In this study, we designed a disaster management human resource development program to analyze issues from the viewpoints of others and create solutions, with the aim of improving the local community's mutual aid ability. In the program, based on the "persona method" used in service development and the processes of "systems thinking" and "design th...
There is a growing need to introduce warning dissemination systems in disaster-prone regions to improve the coverage of information distribution. In this study, a warning dissemination system was designed in which disaster information transmitted by a global navigation satellite system (GNSS) is received by terrestrial infrastructure, such as siren...
The impacts of disasters are increasing due to climate change and unplanned urbanization. Big and open data offer considerable potential for analyzing and predicting human mobility during disaster events, including the COVID-19 pandemic, leading to better disaster risk reduction (DRR) planning. However, the value of human mobility data and analysis...
In various large-scale disasters occurring around the world, information dissemination is important to mitigate damage and save many lives. While history has shown the effectiveness of "temporal dissemination," which is the dissemination of past knowledge and experience over time, "spatial dissemination," which is the early and widespread dissemina...

In this study, we evaluated the effectiveness of an audio distribution system for disaster information designed by the authors, which links navigation satellites and public transportation vehicles, from the viewpoint of spatial coverage rate of information transmission. In the designed system, immediately after the occurrence of a large- scale disa...
In the event of a large-scale disaster, the dissemination of audible disaster warning information via sirens is effective in ensuring a rapid response. Sirens can be installed not only on fixed towers, but also on public transport and other vehicles passing through residential areas, and at spots where residents congregate, to increase area coverag...
The purpose of this research is to design the architecture of an early warning system with Global Navigation Satellite System (GNSS) and terrestrial infrastructure for improving coverage of disaster information dissemination. In the proposed architecture, necessary segments and information flow are identified to introduce an early warning system to...
