摘要：

Timely and rapid assessment of post-earthquake loss is important to mitigate earthquake disaster. In practice, however, earthquake related data are complex and spatial heterogeneous, making it difficult to evaluate the earthquake disaster quickly and accurately. It is very necessary and urgent to construct a platform to prevent and mitigate earthquake disaster. Compared with the existing earthquake data management methods, which assume the data are distributed evenly in the whole area, this paper proposed a seismic multi-level hybrid grid system (SMHGS). The core idea of SMHGS is using multi-level spatial hybrid grid to manage the earthquake related data and fully consider the spatial heterogeneous of these data. With SMHGS, the efficiency of data management is improved. The proposed approach was exemplified in Yushu earthquake (Ms 7.1) in China in 2010. The case applications show that the SMHGS can effectively manage and analyze massive earthquake data. As the system has run very stably, it can be recommended to a national level of China. © 2016, UK Simulation Society. All rights reserved.
