Abstract:
Global Volcano Mortality Risks and Distribution is a 2.5 minute grid representing global volcano mortality risks. The data set was constructed using historical hazard-specific mortality loss data from the Emergency Events Database (EM-DAT) maintained by the Centre for Research on the Epidemiology of Disasters (CRED), subnational year 2000 population estimates from Gridded Population of the World, ... Version 3 (GPWv3), and volcano hazard data from the Global Volcano Hazard Frequency and Distribution dataset. Estimates were made as to the mortality numbers associated with volcano hazard. In turn, these mortality estimates were classified into deciles, 10 class of an approximately equal number of grid cells of increasing mortality risk. 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) format 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 means of assessing global volcano mortality risks and distribution.

Quality
The records of the Emergency Events Database (EM-DAT), collected over a 20 year period from 1981 to 2000, provide regional, hazard-specific mortality and economic loss rates. A crude estimation of the global volcano hazard mortality is developed using the EM-DAT regional mortality rates, population distributions from Gridded Population of the World, Version 3 (GPWv3), and frequency/distribution ... data from Global Volcano Hazard Frequency and Distribution. To better reflect the confidence associated with the result, mortality figures are classified into deciles, 10 classes of an approximately equal number of grid cells of increasing mortality (item Value). 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 origins. 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 has been calculated, this value is further divided by the total population within the subnational unit. This subnational, per-person GDP value is multiplied by the grid cell population density to determine a GDP value for the grid cell. The GDP values presented in this dataset (item Gdpvalue) are not projections of impacted GDP, but rather the estimates of GDP that serve as a baseline for estimating hazard impacts. Furthermore, Gdpvalue is indicative of the GDP associated with each of the hazard risk deciles and not the individual grid cell.
Estimating the agricultural GDP (item Agvalue) follows a process similar to GDP. The amount of agricultural GDP is derived at the subnational unit using available data of various origins.
