Global Earthquake Proportional Economic Loss Risk Deciles

The Global Earthquake Proportional Economic Loss Risk Deciles is a 2.5 minute grid of earthquake 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).

全球地震相对经济损失风险十分位数据集，以2.5分钟网格为单位，展示了地震灾害经济损失占国内生产总值（GDP）的比例。该数据集的风险GDP损失估计基于历史紧急事件数据库（EM-DAT）中得出的区域经济损失率。损失率根据灾害发生的频率和分布进行加权。本数据集采用Sachs等人在2003年的方法来确定每个网格单元的GDP基线估计值。为更准确地反映数据与程序的不确定性，将损失比例的范围划分为十分位，即风险逐渐增加的网格单元数量的10个等分。该数据集是哥伦比亚大学灾害与风险研究中心（CHRR）、国际复兴开发银行/世界银行以及哥伦比亚大学国际地球科学信息网络中心（CIESIN）合作的结果。
