This paper aims to clarify the usefulness and limitations of disaster prevention information sharing infrastructure system built for sending alerts, for subsequent verification. As a case study, we analyzed data on disaster prevention weather information and evacuation advisory transmitted during the heavy rain of Typhoon No. 19 in 2019. As a result of analysis, the temporal transition and spatial distribution of disaster prevention information were quantitatively clarified. As a result of the analysis, we quantitatively showed the temporal transition and the spatial distribution of the number of municipalities that transmitted disaster prevention information. It was shown that the analysis method used can verify the effect of measures related to evacuation information.
