Global Multihazard Frequency and Distribution

The Global Multihazard Frequency and Distribution is a 2.5 minute grid presenting a simple multihazard index based solely on summated single-hazard decile values. The hazards of interest include cyclones, droughts, earthquakes, floods, landslides, and volcanoes. This data set is further enriched by the inclusion of data pertaining to population, Gross Domestic Product (GDP), and transportation infrastructure. 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).

全球多灾害发生频率与分布数据集（The Global Multihazard Frequency and Distribution）采用2.5弧分分辨率网格，构建了仅基于单一灾害十分位分级值求和的简易多灾害指数。该数据集涵盖的灾害类型包括气旋、干旱、地震、洪水、滑坡与火山灾害。本数据集还纳入了人口、国内生产总值（GDP）以及交通基础设施相关数据以丰富数据维度。本数据集由哥伦比亚大学灾害与风险研究中心（Columbia University Center for Hazards and Risk Research, CHRR）、国际复兴开发银行/世界银行（International Bank for Reconstruction and Development/The World Bank）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, CIESIN）联合研发完成。
