Global Volcano Hazard Frequency and DistributionEntry ID: CIESIN_CHRR_NDH_VOLCANO_HFD
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).
The data in American Standard Code for Information Interchange (ASCII) format 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 provide a means of assessing the relative distribution and frequency of global volcano hazard.

ISO Topic Category
Quality National Geophysical Data Center (NGDC) provides a database of nearly 4,000 volcanic events categorized from 2 to 8 according to VEI from 79 through 2000 nominally georeferenced to the nearest tenth or hundredth of a degree. Global Volcano Hazard and Frequency was based upon the frequency of volcanic events, irregardless of severity, within a 2.5 minute grid cell. The frequency range was classified into 10 classes of an approximately equal number of grid cells, whereby a higher value denotes a greater risk as posed by volcanic activity. Note that areas of no data are not necessarily without hazard risk but may be an artifact of a mask that excluded from analysis those areas where the population density was less than 5 persons per square kilometer and were without significant agriculture.
