Global Volcano Total Economic Loss Risk Deciles

Abstract: distributions of Gross Domestic Product (GDP) are computed using a two-fold process. Where

applicable, the proportional contribution of subnational units are determined following the methodology of Sachs et al. (2003) and

these proportions are used against World Bank Development Indicators to determine a GDP value for the subnational unit. Once a

national GDP has been spatially stratified into the smallest administrative units available, it is further distributed based upon

Gridded Population of the World, Version 3 (GPWv3) population distributions. A per capita contribution value is determined for each

unit, and this value is multiplied by the population per grid cell. Once the GDP has been determined on a per grid cell basis, then

the spatially variable loss rate as derived from EM-DAT historical records is used to determine the total economic loss posed to a

grid cell by volcano hazards. The final surface does not present absolute values of total economic loss, but rather a relative decile

(1-10) ranking of grid cells based upon the calculated economic loss risks. This dataset is the result of collaboration among the

Columbia University Center for Hazards and Risk Research (CHRR), International Bank for Reconstruction and Development/The World

Bank, and Columbia University Center for International Earth Science Information Network (CIESIN).

Purpose: To provide insight into the relative frequency, distribution, and potential impact of global

volcano hazard events to subnational distributions of GDP.
