Abstract
The ability to rapidly assess the loss of earthquake-stricken area after an earthquake in the absence of on-site information is of significant importance. Due to the unique geology, geomorphology, building structures as well as the social and economic situation in Yunnan, it makes the loss of building and casualties having some differences with other regions when the earthquake occurred. Based on the regional characteristics of Yunnan, this paper assesses the area of destroyed houses, economic loss, the number of earthquake deaths and number of homes lost using multiple models-a building earthquake death model, a destroyed houses model, an economic loss model and a homes lost model. This inturn allows the distribution pattern of the various losses to be displayed on a map by integrating the evaluation model and GIS technology. The value of spatial distribution is more important than simple statistical data as spatial distribution helps us understand the distribution of earthquake damage thus allowing targeted command decisions to be made for technical support of earthquake victims and earthquake-affected areas.
