Utilization of Social Media at the Time of Disaster

Abstract

It is crucial to collect, transmit, and share disaster-related information quickly and accurately to minimize damage in the event of a disaster. From this point of view, the use of social media during disasters is attracting more attention lately. In recent years, the number of administrative agencies utilizing or considering the use of social media for the transmission and collection of disaster-related information has been increasing. The number of social media posts increases explosively at the time of a disaster, but it has been pointed out that necessary information is buried, and rumor and inaccurate information spread rapidly and widely. In this paper, we introduce examples of the use of social media during disasters and related research trends. Moreover, in this paper, several of the results of our studies on the utilization of Twitter at the time of a disaster are introduced.
