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).

全球多灾种频率与分布数据集采用2.5分钟网格展示，该数据集基于单一灾种十分位值之和构建了一个简单的多灾种指数。所关注的灾种包括台风、干旱、地震、洪水、山体滑坡和火山爆发。此外，数据集还融入了与人口、国内生产总值（GDP）以及交通基础设施相关的数据。本数据集系哥伦比亚大学灾害与风险研究（CHRR）中心、世界银行重建与发展银行以及哥伦比亚大学国际地球科学信息网络（CIESIN）中心合作的结果。
