Global Volcano Hazard Frequency and Distribution
Entry ID: CIESIN_CHRR_NDH_VOLCANO_HFD


Summary
Abstract: Global Volcano Hazard Frequency and Distribution is a 2.5 minute gridded data set based upon the

National Geophysical Data Center (NGDC) Volcano Database spanning the period of 1979 through 2000. This database includes nearly

4,000 volcanic events categorized as moderate or above (values 2 through 8) according to the Volcano Explosivity Index (VEI). Most

volcanoes are georeferenced to the nearest tenth or hundredth of a degree with a few to the nearest thousandth of a degree. To

produce the final output, the frequency of a volcanic hazard is computed for each grid cell, with the data set consequently being

classified into deciles (10 classes of approximately equal number of grid cells). The higher the grid cell value in the final output,

the higher the relative frequency of hazard posed by volcanoes. This dataset is the result of collaboration among the Columbia

University Center for Hazards and Risk Research (CHRR) and Columbia University Center for International Earth Science Information

Network (CIESIN).


Purpose: To provide a means of assessing the relative distribution and frequency of global volcano

hazard.
