Abstract：The paper explores the present situation,hotspots and trends of earthquake early warning research in China,and provides reference for future researchers.Based on 818 journal papers collected by CNKI,CiteSpace software was used for a visualized analysis of information,including authors,institutions and keywords.The re-sults show that in terms of research status,the annual number of published papers shows obvious stage characteris-tics,the authors of the published papers show a state of"generally dispersed and locally concentrated",and there is less cooperation between research institutions,while the high-yield institutions have close cooperation,clear and intersecting research topics.The current research hotspots can be summarized as earthquake magnitude estimation,artificial intelligence earthquake early warning,earthquake early warning service and high-speed rail-way earthquake early warning.The research on earthquake early warning shows a trend of continuous increase in the number of annual publications and rapid update of topics.In the future,in-depth research can be carried out around the new methods of earthquake early warning and the refinement of early warning services.
