Most earthquake loss studies use an inventory approach by which the predicted damages in various categories of structures and facilities in a concerned region are estimated and added together to obtain the total estimated. Such an approach requires a detailed inventory database of the structures and facilities in the region, which is not always readily available in many regions of the world. Therefore, an alternative means of estimating earthquake losses is used based on several macroeconomic indices such as the gross domestic product (GDP) and population. Based on the published earthquake loss data during 1980—1995, the relations between GDP and earthquake losses have been formulated empirically for several intensity ranges. The world’s land surface was divided into unit cells with 0.5°×0.5°in size, the GDP of each cell was apportioned based on its population and the GDP and population of the region to which it belongs. The predicted seismic loss of the cell was then estimated from the seismic haza
