Abstract (in Japanese) (See Japanese page) 
(in English) To minimize damage during disasters, the rapid collection and delivery of accurate information are essential. From this perspective, the use of social media, especially Twitter, in the case of a disaster has been attracted worldwide attention.
In this study, we extracted tweets with attached images from tweets posted at the time of the 2019 typhoon Hagibis, the 2018 Osaka North Earthquake, and the 2018 Western Japan Heavy Rain Disaster, and developed a system to simultaneously visualize the contents of the tweets and the attached images related to the contents. In addition, the developed system was used to discuss the changes in the time of day and the differences in the types of disasters.
