The Economic Loss Evaluation of Earthquake Disaster and Simulation Verification Model Based on the Neural Network

the evaluation and estimate of the loss and damage in earthquake disaster is an important factor for earthquake emergence and post-earthquake reconstruction decision-making. The article firstly selected the evaluation index for the economic loss of earthquake disaster by the method of factor analysis; then established the evaluation model of economic loss in earthquake disaster based on neural network, and performed training to the data collected and the network; finally forecasted the economic loss in earthquake by the trained network, comparing and testing the results of regression analysis. The testing result indicated that the model has a preferable feasibility and practicability.
