Global Volcano Proportional Economic Loss Risk Deciles

Global Volcano Proportional Economic Loss Risk Deciles is a 2.5 minute grid of volcano hazard economic loss as proportions of Gross Domestic Product (GDP) per analytical Unit. Estimates of GDP at risk are based on regional economic loss rates derived from historical records of the Emergency Events Database (EM-DAT). Loss rates are weighted by the hazard's frequency and distribution. The methodology of Sachs et al. (2003) is followed to determine baseline estimates of GDP per grid cell. To better reflect the confidence surrounding the data and procedures, the range of proportionalities is classified into deciles, 10 class of an approximately equal number of grid cells of increasing risk. This data set 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).

全球火山比例经济损失风险十进制数据集系基于分析单元的火山危害经济损失与国内生产总值（GDP）之比构建的2.5分钟网格数据。该数据集对风险GDP的估计基于从紧急事件数据库（EM-DAT）的历史记录中推导出的区域经济损失率，并按灾害的频率和分布进行加权。本数据集遵循Sachs等人（2003年）的方法论来确定每个网格单元的GDP基线估计值。为了更好地反映数据及程序的置信区间，比例范围被划分为十进制，即按风险递增的网格单元数量大致相等的十个类别。该数据集是哥伦比亚大学灾害与风险研究（CHRR）、世界银行下属的国际重建与发展银行（IBRD）以及哥伦比亚大学国际地球科学信息网络中心（CIESIN）合作的成果。
