Abstract:Destructive earthquakes often lead to serious economic losses and casualties, so it is important to evaluate the value of earthquake loss, for it can help to improve the seismic capacity and reduce the loss of earthquake disasters. In seismic data processing, traditional spatial models cannot deal with the interference of big data on the spatial scale selection, and drawbacks of large deviation and high volatility of seismic loss assessment results must be faced. Therefore, this study designs a seismic loss assessment model based on the cloud computing platform, HAZ-China. The service levels, seismic application service layer, and system structure of the cloud computing platform, HAZ-China, were designed to provide pre-, co-, and post-seismic loss value evaluation services. The model can realize the storage and analysis of big data, then design the building damage database and cloud computing model using the distributed database, HBase. The model can accurately evaluate the seismic loss value through a comprehensive assessment of the seismic disaster loss. The experimental results showed that the designed model can realize an accurate evaluation of the value of earthquake loss, and had high convergence, efficiency, and stability.
