To understand the present and future status of disaster social media, the purpose of this paper is to systematically summarize the topic distribution, characteristics, and development trends of disaster social media research. Design/Methodology/Approach: By using Bibexcel, R and Ucinet, temporal-spatial analysis, clustering analysis, and social network analysis are performed on a bibliometric dataset of disaster social media articles obtained from the Web of Science database. And then, based on the results of the clustering and social network analyses, several major topics under the perspectives of emergency management and information dissemination were qualitative summarized in detail. Based on the results of the temporal-spatial analysis and qualitative analysis, the hot topics and future trends in disaster social media research are identified. Findings: The results indicate that the available research hot topics and methods are becoming highly diverse, and dynamics analysis, quantitative mining, and emotional calculations may become a future trend in social media research.
