Global Earthquake Mortality Risks and Distribution

The Global Earthquake Mortality Risks and Distribution is a 2.5 minute grid of global earthquake mortality risks. Gridded Population of the World, Version 3 (GPWv3) data provides a baseline estimate of population per grid cell from which to estimate potential mortality risks due to earthquake hazard. Mortality loss estimates per hazard event are calculated using regional, hazard-specific mortality records of the Emergency Events Database (EM-DAT) that span the 20 years between 1981 and 2000. Data regarding the distribution of earthquake hazard are obtained from the Global Earthquake Hazard Distribution-peak ground acceleration data set. In order to more accurately reflect the confidence associated with the data and procedures, the potential mortality estimate range is classified into deciles, 10 classes of increasing risk with an approximately equal number of grid cells per class, producing a relative estimate of earthquake-based mortality risks. 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).

全球地震死亡率风险及其分布是一项基于2.5分钟网格的全球地震死亡率风险数据集。世界人口网格化数据集（Gridded Population of the World, Version 3, 简称GPWv3）提供了每个网格单元的人口基线估计，据此可估算因地震灾害而可能导致的死亡率风险。针对每个灾害事件的死亡率损失估计，是通过使用紧急事件数据库（Emergency Events Database, 简称EM-DAT）中的区域特定灾害死亡率记录来计算的，这些记录涵盖了1981年至2000年间的20年。关于地震灾害分布的数据来源于全球地震灾害分布-峰值地面加速度数据集。为了更精确地反映数据及程序相关的置信度，潜在死亡率估计范围被划分为十等分，即10个风险递增的类别，每个类别具有大致相等的网格单元数量，从而产生基于地震的死亡率风险的相对估计。该数据集是哥伦比亚大学灾害与风险研究中心（Columbia University Center for Hazards and Risk Research, 简称CHRR）、国际重建与发展银行/世界银行以及哥伦比亚大学国际地球科学信息网络中心（Columbia University Center for International Earth Science Information Network, 简称CIESIN）之间合作的结果。
