Recent trends in disaster information dissemination for natural disasters are leveling, meshing and high resolution to reduce the lead time for evacuation, and weather disaster warning being increasing and diversifying. However, disaster information of risk communication does not have to be scientifically accurate, precise, and detailed.
It is difficult to accurately predict the occurrence of weather-related disasters or natural disaster in the first place. And even with the increase and diversification of weather information, there is no information that can be called definitive enough to lead to evacuation. It is not right to tell people the risks as they are. Even if you understand the risks accurately, you should evacuate just in case, or if you do not understand the risks accurately, you should feel the risks more than necessary or evacuate earlier.
It is important to make a clear distinction between the goal of disaster prevention, which is to provide information to protect human lives, and the goal of outreach, which is to deepen understanding of seismology, volcanology, and meteorology and to provide information based on academic knowledge.
