Global Volcano Hazard Frequency and Distribution

Mar 4, 2011 (Last modified Mar 8, 2011)
Description
Global Volcano Hazard Frequency and Distribution is a 2.5 by 2.5 minutegridded data set based upon the National Geophysical Data Center (NGDC)Volcano Database spanning the period 79 through 2000. This databaseincludes 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 adegree with a few to the nearest thousandth of a degree. To produce thefinal output, the frequency of a volcanic hazard is computed for eachgrid cell, with the data set consequently being classified into deciles(10 classes of approximately equal number of grid cells). The higher thegrid cell value in the final output, the higher the relative frequencyof hazard posed by volcanoes. The dataset is a result of the collaboration among the Center for Hazards and Risk Research (CHRR) , and the Columbia University Center for International Earth Science Information Network (CIESIN).
