Regional Earthquake Disaster Macro Risk Assessment Model Research

Abstract:

Regional earthquake disaster macro risk assessment model can be devided into two parts:economic losses and casualities. through the compare of domestic earthquake disaster as-sessment model,the existing model evaluation index is sole,and it can not reflect the differences of urban earthquake disaster in the area,according to this we built the regional seismic disaster evaluation index system, and use the PCA method to analyze the index,and get the weights of each index,further to build the regional seismic disaster economic loss evaluation index system effectde by multiple in-dex.Take the previous data between 1996 to 2009 as an example to analyze,compare the reckoning and the existing model evaluate results,and check the effectiveness and feasibility of the model.
