Newberry Volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shield-shaped volcano measuring 60 km north-south by 30 km east-west with a maximum elevation of more than 2 km above sea level. It is the product of deposits from thousands of eruptions, including at least 25 in (approximately) the last 12,000 years (the Holocene Epoch). Newberry Volcano has erupted as recently as 1,300 years ago, but isotopic ages indicate that the volcano began its growth as early as 0.6 million years ago. Such a long eruptive history together with recent activity suggests that Newberry Volcano is likely to erupt in the future. This DEM (digital elevation model) of Newberry Volcano contributes...

Global Volcano Mortality Risks and Distribution is a 2.5 by 2.5 minute grid representing global volcano mortality risks. The data set was constructed using historical hazard-specific mortality loss data from the Emergency Events Database (EM-DAT) maintained by the Centre for Research on the Epidemiology of Disasters (CRED), subnational year 2000 population estimates from Gridded Population of the World (GPW) version 3.0 (beta), and volcano hazard data from the Global Volcano Hazard Frequency and Distribution dataset. Estimates were made as to the mortality numbers associated with volcano hazard. In turn, these mortality estiamtes were classified into deciles, 10 class of an approximately equal number of grid cells...

Global Volcano Proportional Economic Loss Risk Deciles is a 2.5 by 2.5 minute grid of volcano hazard economic loss as proportions of gross domestic product (GDP) per analytical unit. Estimates of GDP at risk are based on regional economic loss rates derived from historical records of the Emergency Events Database (EM-DAT). Loss rates are weighted by the hazard's frequency and distribution. The methodology of Sachs et al. (2003) is followed to determine baseline estimates of GDP per grid cell. To better reflect the confidence surrounding the data and procedures, the range of proportionalities is classified into deciles, 10 class of an approximately equal number of grid cells of increasing risk. The dataset is a result...

This dataset is a compilation of all available multibeam and single-beam sonar bathymetry in the Eastern Samoa Volcanic Province (ESVP) as of November 20, 2007. Bathymetric datasets were compiled and gridded using the software package MB-System. Cell resolution is 200 meters.

Global Volcano Hazard Frequency and Distribution is a 2.5 by 2.5 minute gridded data set based upon the National Geophysical Data Center (NGDC) Volcano Database spanning the period 79 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...

Global Volcano Total Economic Loss Risk Deciles is a 2.5 by 2.5 minute grid of global volcano total economic loss risks. First, subnational distributions of GDP are computed using a two-fold process. Where applicable, the proportional contribution of subnational units are determined following the methodology of Sachs et al. (2003), and these proportions are used against World Bank Devleopment Indicators to determine a GDP value for the subnational unit. Once a national GDP has been spatially stratified into the smallest adminstrative units available, it is further distributed based upon Gridded Population of the World Version 3.0 (beta) population distributions. A per capita contribution value is determined for...

This digital map database is compiled from unpublished data andnew mapping by the authors, represents the general distribution ofsurficial and bedrock geology in the mapped area. Together withthe accompanying pamphlet, it provides current information on thegeologic structure and stratigraphy of the area. The databasedelineates map units that are identified by age and lithologyfollowing the stratigraphic nomenclature of the U.S. GeologicalSurvey. The scale of the source maps limits the spatialresolution of the database to 1:31,680 or smaller.

This report contains all of the available daily sulfur dioxide andcarbon dioxide emission rates from Cook Inlet volcanoes asdetermined by the U.S. Geological Survey (USGS) from March 1990through July 1994. Airborne sulfur dioxide gas sampling of theCook Inlet volcanoes (Redoubt, Spurr, Iliamna, and Augustine)began in 1986 when several measurements were carried out atAugustine volcano during the eruption of 1986. Systematic monitoringfor sulfur dioxide and carbon dioxide began in March 1990 atRedoubt volcano and continues to the present. Intermittentmeasurements at Augustine and Iliamna volcanoes began in 1990 andcontinues to the present. Intermittent measurements began at Spurrvolcano in 1991, and were continued...
