Abstract:
Global Multihazard Proportional Economic Loss Risks is a 2.5 minute grid of a multihazard-based economic loss risk as a proportion of the economic productivity of the analytical unit, the grid cell. Representation of multihazard risk is not based on a multihazard index but rather on combinations of hazard risk categories, drought, seismic, and hydro. The drought category includes drought only. The ... seismic category consists of earthquake and volcano hazards. Cyclones, floods, and landslides are included in the hydro category. For each of the six hazards considered, a binary risk surface is constructed utilizing the three most-at-risk deciles of each hazard's global proportional economic loss risks dataset (deciles 8-10). Each of the category risk surfaces are constructed by adding all the relevant hazard high-risk surfaces. These categorical risk surfaces are reclassified into binary high-risk surfaces. The combination of the category risk values forms a three digit identifier for determining those locations that are at higher-risk from multihazards. 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 that are at greater risk of multihazard proportional economic loss.

Quality
The production of the multihazard surface began by isolating those deciles most at-risk (deciles 8-10) of the individual hazard surfaces (Global Cyclone Proportional Economic Loss Risks, Global Drought Proportional Economic Loss Risks, etc.). These surfaces are reclassified into binary representing those areas considered most at-risk. Hazard categories are created by grouping specific hazards ... together. The categories are as follows:
Drought - droughts Seismic - earthquakes and volcanoes Hydro - cyclones, floods, and landslides
A binary highest-risk surface at the category-level was produced by summing the individual hazards and reclassifying as true all sums greater than zero.
