The risk for urban earthquake disasters has aggravated. Hence，the need for the establishment of a service system for earthquake disaster risk prevention and control has never been more urgent. This study analyzed the major challenges and actual level of the prevention and control of earthquake disaster risks in Tianjin. On the basis of the work that had been completed on the prevention and control of earthquake disaster risks in Tianjin，we focused on the research achievements and key techniques of earthquake risk investigation and assessment，earthquake disaster risk investigation and assessment，and earthquake disaster risk early warning. On this basis，with the problem，demand，and goal orientations of Tianjin earthquake disaster risk prevention and control，we propose establishing an earthquake disaster risk prevention and control service system with the investigation，assessment，governance，and service of earthquake disaster risk as the main line. Furthermore，we provide two major suggestions supporting service systems for the prevention and control of urban earthquake disaster risks in Tianjin during the "Fourteenth Five Year Plan" period.
