摘要:
The scientific and policy communities have become increasingly aware, in recent years, of the vulnerability of developed and developing countries to drought. This awareness has been heightened by the widespread occurrence of severe, multiyear droughts that have produced serious socioeconomic and environmental consequences on a global scale. However, the occurrence of relatively short‐term droughts (e.g., the 1986 drought in the southeastern United States) has also resulted in severe impacts. Often, impacts of both short‐term and multiyear droughts have been exacerbated by poorly conceived or nonexistent assessment and response strategies by governme

摘要:
We have been investigating the possibility of drilling a 600‐m deep hole into the volcanic hydrothermal system on White Island, an active andesitic volcano located in the Bay of Plenty, 50 km off the coast of New Zealand (Figure 1). A number of important hydrothermal and volcanic problems of worldwide occurrence can be addressed by drilling into this volcano. The principal goals are to characterize the chemistry and distribution of the fluids within the volcanic hydrothermal system and the related alteration mineralogy, to investigate fluid migration during magma:water interaction, and to investigate the extent to which physical rock properties influence the hydrology of such a system.This study will improve our understanding of magma:magmatic fluid:groundwater interactions at high levels in an andesitic volcano; the fluids and flow processes in an active volcanic hydrothermal system; the processes of metal transport and deposition in this acidic, ore‐forming environment; and the geophysical signatures that remain as the system co

摘要:
The Symposium on the Seismicity of the Great Lakes Region was held April 21, 1988, at the University of Akron, Ohio, in connection with the 22nd Annual Meeting of the North‐Central Section of the Geological Society of America, sponsored by the Department of Geology, University of Akron.The purpose of this symposium was to reassess the seismicity of the region and its relationship to tectonic features in view of the unexpectedly strong earthquake of January 31, 1986, near the Perry nuclear power plant in northeast Ohio. A total of 13 papers were presented to an audience of about 60–70. Abstracts of these papers appear inAbstracts with Programs, Geological Society of America, volume 20, number 5, March 1

摘要:
With this VGP News column, I conclude my 3.5 years as VGP Editor of Eos and turn the job over to William H. Casey. As a convenience to our readers, the address to which your cards and letters should be sent remains the same. But while the editor's abode is unchanged, the personal scientific focus of the editor changes from magma to muck.Bill concerns himself with fluids and rocks and mixtures thereof at low temperature, and he is a vigorous researcher and prolific writer in this area. I know his scientific preference will come as a relief to those of you who think that if you've seen one volcano, you've seen them all. Seriously though, the change will help to give an overall balance toEos' coverage. Volcano news is now rolling in without the need of encouragement from the VGP Editor.

摘要:
A conclusion of the Geological Society of America Penrose Conference on Volcanic Influences on Terrestrial Sedimentation (August 28 to September 2, 1988) was that establishment of an informal working group would enhance our understanding of volcanogenic sedimentation. To establish the group, an ad hoc steering committee was formed at the conference and consists of W. J. Fritz (Georgia State University), R. S. Hildebrand (Geological Survey of Canada), R. Iverson (U.S. Geological Survey), P. Kokelaar (Chairman, University of Liverpool), T. C. Pierson (USGS), and G. A. Smith (University of New Mexico). The working group is open to researchers of any nation interested in the study of secondary transport and deposition of volcaniclastic materials in subaerial or subaqueous environments (e.g., transport, deposition, nomenclature, volcanic history, experiment, theory, hazard).
