Research on hotspots and frontier evolution of earthquake disasters in China based on CiteSpace

Abstract

Based on the literatures in the field of earthquake disaster research in China in the past 20 years (2003—2022) collected by China Knowledge Network, this article studied the overall distribution, research hotspots and frontier evolution trajectory of earthquake disaster research using the scientometric software CiteSpace. The results show that in the past 20 years, there has been a limited number of literatures on earthquake disaster research, which is closely related to earthquake events. Research institutions mainly focus on functional departments responsible for earthquake work, and the main research hotspots are focused on obtaining disaster data and extracting disaster information. After analysis, the evolution trajectory of earthquake disaster research can be divided into the initial stage, development stage, and deepening stage. The current research hotspots mainly focuses on the acquisition of disaster data, which is in the early stage of earthquake disaster research and an important stage of laying a solid foundation. In the future, the research on earthquake disasters in China should strengthen the integration of disciplines, pay attention to expanding the research direction of disaster information extraction, disaster reporting and release, and realize the intelligence, dynamics and three-dimensional of earthquake disasters by combining mainstream technologies.
