Abstract:
Global Volcano Total Economic Loss Risk Deciles is a 2.5 minute grid of global volcano total economic loss risks. First, subnational 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).
The data in American Standard Code for Information Interchange (ASCII) and dBASE (DBF) formats and a map in Portable Document Format (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose:
To provide a spatial surface of the total economic impacts of global volcano hazard.

The population per grid cell (item Pop) is based upon the population data of Gridded Population of the World, Version 3 (GPWv3). The area per grid cell (Areakm) is calculated by subtracting from the area of the grid cell those areas that are permanently inundated as identified using VMAP (0)/Digital Chart of the World. Building upon a methodology developed by Sachs et al. (2003), a Gross Domestic ... Product (GDP) value (US$, 2000, purchase power parity adjusted (PPP)) is estimated for each grid cell. The process begins by determining the contribution of each subnational unit to national GDP using data of varied origin. The ratio of the subnational production to the national GDP is the contribution ratio. To ensure uniformity between countries, these contribution ratios are utilized with published World Bank estimates of GDP.
Once a standardized version of subnational GDP had been calculated, this value was further divided by the total population within the subnational unit. This subnational, per-person GDP value was multiplied by the grid cell population density to determine a GDP for the grid cell.
Regional loss rates derived from the historical records of EM-DAT were utilized in conjecture with the vulnerability data within Global Volcano Hazard Frequency and Distribution and the GDP per grid cell to assess the total economic loss risks posed by volcano hazard. Since the resultant range of economic loss risks varied widely, the natural log was taken before classifying into deciles, 10 classes of approximately an equal number of grid cells.
