Global Multihazard Mortality Risks and Distribution

The Global Multihazard Mortality Risks and Distribution is a 2.5 minute grid identifying and characterizing the nature of multihazard risk at the global scale. For this study, multihazard considers the hazards posed by cyclones, droughts, earthquakes, floods, landslides and volcanoes. The specific hazards are grouped into the following hazard categories: drought (drought), seismic (earthquakes and volcanoes), and hydro (cyclones, floods, and landslides). Each grid cell is assessed for each hazard category; and is considered at high risk or not at high risk. Treated as a binary value, the at-risk values of the hazards categories function as a 3-digit index of multihazard.

For each of the hazard category combinations, aggregate analyses determine the total population, area, and length of major transportation features, as well as, the value of Gross Domestic Product (GDP) and agricultural GDP. 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).

全球多灾害死亡率风险及其分布数据集，以2.5分钟的网格形式识别并描述全球尺度上多灾害风险的本质。在本研究中，多灾害考虑了由台风、干旱、地震、洪水、滑坡和火山带来的风险。具体风险被划分为以下风险类别：干旱（干旱）、地震（地震和火山）以及水灾（台风、洪水和滑坡）。每个网格单元都会针对每个风险类别进行评估，并被视为高风险或非高风险。将这些风险类别的风险值视为二元值，它们作为多灾害的3位指数。对于每种风险类别组合，通过汇总分析确定总人口、面积、主要交通设施的长度，以及国内生产总值（GDP）和农业GDP的价值。此数据集是哥伦比亚大学灾害与风险研究中心（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（CIESIN）合作的结果。
