Abstract. Our world is prone to more frequent, deadly and costly earthquake disasters, which are increasingly uncertain and complex due to the rapid environmental and socio-economic changes occurring at multiple scales. There is an urgent need to recover rapidly and effectively for community after earthquake disasters. To enhance community recovery, it is necessary to have a good initial understanding of what it is, its determinants and how it can be measured, maintained and improved. So this article proposes the concept of community recovery as the capacity to recover and rebuild after the earthquake disasters by considering the original perspective of recovery. And we develop a new quantitative approach to measure community recovery to earthquake from four dimensions (population, economic, building, and infrastructure) by extending the concepts of recovery triangle. Taking the community of Wenchuan as the example to test our mathematical model and compare different recovery levels of four dimensions under the situation of Wenchuan Earthquake, the results can help the policy makers identify the low-recovery dimensions of Wenchuan to enhance post-disaster recovery and reconstruction efforts, and address the vital importance of local government in improving the post-disaster recovery.

Short summary
Our research defined community recovery as the capacity to recover and rebuild itself rapidly to an acceptable level of functioning and structure following the earthquake disasters occur, and developed a quantitative approach for measuring and characterizing the community recovery in four dimensions to guide planning of appropriate response and reconstruction policies, and emphasizing that the community recovery is strongly influenced by the decision making of local governments.
