Abstract

In view of the need of relative exposure, as background data, in the geospatial information diffusion model, this paper defines “exposure to natural disaster risk” and “relative exposure”. Dividing “the product of the disaster and the parameter affecting the disaster with respect to a risk bearing body lightly affected by disaster” by “the product to a body severely affected”, we quantify the exposure of the body lightly affected relative to the body severely affected. The study shows that risk exposure to natural disasters consists of three parts: the exposure to risk source, the exposure to vulnerability, and the exposure to value. Statistical data can be used to make a scale for measuring the relative exposure of each geographic unit in the risk zone.
