The application of the disaster losses macroscopic forecasting model in the rapid assessment after earthquak

The rapid assessment of seismic losses currently is mainly based on two methods, which are construction damage matrix and macroeconomic dada based on the GDP. Compared with the building damage matrix method in data collection, the macro vulnerability assessment method based on GDP is easier, and it develops from the process of seismic losses in the global scale. This method can be used in the provincial-level administrative units of the small-scale earthquake damage assessment, there are still uncertainties. This paper analyses the application of the macro vulnerability assessment method in the provincial rapid assessment after an earthquake, by comparing model results with real expedition earthquake damage loss of data.
