Abstract: In general the strong earthquakes are widely distributed and frequently in China. Actual hazards and potential threats of strong earthquakes are the major challenges of the urban security development. The painful lessons learnt show that the disaster defenseless city is very likely to be destroyed by the strong earthquake. In order to realize the urban sustainable security development, we have to pay enough attention to building up the anti-earthquake capabilities for effectively preventing and eliminating the risk of earthquake disaster. In this paper, we analyzes the factors affecting urban earthquake disasters, and put forward the countermeasures and suggestions for further strengthening urban disaster prevention capacity building, from the aspects of earthquake disaster prevention capacity building, risk prevention and control of urban earthquake disaster, formulating laws and regulations, technical standards and evaluation system.
