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 dataset 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).
To identify areas of the world at multihazard risk and to gain insight into the nature of
this risk posed.
