Below is a listing of the various sets of hazard curves created for this update. Please note that each of these files contains data for specific parameters and sub-regions of Alaska and may contain zero-values at locations that do not meet the specific criteria for that file. This does not mean the hazard was zero, but rather much more likely that the specific location did not match the parameters of the file. The listing below names every file, however for a more complete description of each download, please see Table 3 in the Open-File Report .
