Fractionation of families of major, minor, and trace metals across the melt-vapor interface in volcanic exhalations Fractionation of families of major, minor, and trace metals across the melt-vapor interface in volcanic exhalations
Chemical families of metals fractionate systematically as they pass from a silicate melt across the interface with the vapor phase and on into a cooled volcanic plume. We measured three groups of metals in a small suite of samples collected on filters from the plumes of Kilauea (Hawaii, USA), Etna (Sicily), and Merapi (Java) volcanoes. These were the major, minor, and trace metals of the...

The 1989-1990 eruptions of Redoubt Volcano: an introduction The 1989-1990 eruptions of Redoubt Volcano: an introduction
Redoubt Volcano, located on the west side of Cook Inlet in south-central Alaska, erupted explosively on over 20 separate occasions between December 14, 1989 and April 21, 1990. Fourteen lava domes were emplaced in the summit area, thirteen of which were subsequently destroyed. The eruption caused economic losses estimated at over $160,000,000 making this the second most costly eruption...

Magmatic vapor source for sulfur dioxide released during volcanic eruptions: Evidence from Mount Pinatubo Magmatic vapor source for sulfur dioxide released during volcanic eruptions: Evidence from Mount Pinatubo
Sulfur dioxide (SO2) released by the explosive eruption of Mount Pinatubo on 15 June 1991 had an impact on climate and stratospheric ozone. The total mass of SO2 released was much greater than the amount dissolved in the magma before the eruption, and thus an additional source for the excess SO2 is required. Infrared spectroscopic analyses of dissolved water and carbon dioxide in glass...

Campground talk and slide show on volcanoes for Chiricahua National Monument Campground talk and slide show on volcanoes for Chiricahua National Monument
The slides and the accompanying script presented here are based on a campground presentation at Chiricahua National Monument in 1994. Examples of eruptions at active volcanoes are used to help the audience visualize events that took place in the National Monument 27 million years ago. This presentation stresses the following themes: 1) The National Monument lies on the flank of an...

Chapter A. The Loma Prieta, California, Earthquake of October 17, 1989 - Loss estimation and procedures Chapter A. The Loma Prieta, California, Earthquake of October 17, 1989 - Loss estimation and procedures
This Professional Paper includes a collection of papers on subjects ranging from evaluation of building safety, to human injuries, to correlation of ground deformation with building damage. What these papers share is a common goal to improve the tools available to the research community to measure the nature, extent, and causes of damage and losses due to earthquakes. These measurement...
Measurements of heat and mass flow from thermal areas in Lassen Volcanic National Park, California, 1984-93 Measurements of heat and mass flow from thermal areas in Lassen Volcanic National Park, California, 1984-93
Rates of heat loss from eight steam-heated thermal areas and one conductively heated thermal area in Lassen Volcanic National Park have been determined from measurements made during the period 1984-93. Total heat discharge at the steam-heated areas is assumed proportional to the rate of steam upflow from underlying reservoirs. The dominant mode of heat loss differs among the areas...

Geochemical changes in crude oil spilled from the Exxon Valdez supertanker into Prince William Sound, Alaska Geochemical changes in crude oil spilled from the Exxon Valdez supertanker into Prince William Sound, Alaska
North Slope crude oil spilled from the T/V Exxon Valdez in March 1989 and contaminated about 500 km of Prince William Sound shoreline. Aliphatic and aromatic hydrocarbons in oil samples collected in August 1990 and June 1992 from beaches on six islands impacted by the spill have been compared with the hydrocarbons from North Slope crude oil taken from the stricken tanker. Degradation...
