Abstract: 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 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).
The data in American Standard Code for Information Interchange (ASCII) and dBASE (DBF) formats and a map in Portable Document Format (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To identify areas of the world at multihazard mortality risk and to gain insight into the nature of this risk posed.

ISO Topic Category
Quality The first step in creating a multihazard surface is to isolate those areas that are the most at-risk for mortality (deciles 8-10) for each of the hazards considered in the study (cyclones, droughts, earthquakes, floods, landslides, and volcanoes). Three categorical hazard surfaces representing the highest mortality risks are created from combinations of the single hazard surfaces. The hazard ... categories are as follows: drought: drought
seismic: earthquakes and volcanoes
hydro: cyclones, floods, and landslides
Each of the hazard category surfaces is binary. To produce the multihazard surface, each of the categorical surfaces is combined into a single surface. Each grid cell of the multihazard surface is attributed with information regarding its value in each of the hazard categories (items Drought3, Seismic3, and Hydro3). This sequence of values forms a unique class of multihazardness.
The population per grid cell is based on Gridded Population of the World, Version 3 (GPWv3). The area per grid cell, in square kilometers, is calculated by subtracting from the area of the grid cell those portions that are permanently inundated. Identification of permanently inundated areas utilizes VMAP(0) data. VMAP(0) data is also used to identify major roads and railroads.
Building upon a methodology proposed by Sachs et al. (2003), a Gross Domestic Product (GDP) value (US$, 2000, purchase power parity adjusted (PPP)) is estimated on a per grid cell basis. First, the contribution of subnational units to national GDP utilizing data of varied origin. The ratio of the subnational production to the national GDP is the contribution rate. To standardize across countries, these contribution rates are applied to published World Bank GDP estimates to determine GDP values of the subnational units.
The standardized, subnational GDP estimate is divided by the total population within the subnational unit to produce a spatially variable per capita GDP estimate.
