The eruptions of Redoubt Volcano between December 14, 1989 and April 26, 1990 triggered flows of snow, ice, water, sediment, and debris that traveled down the Drift River as far as its mouth, about 40 km downstream. A major explosive eruption and dome collapse on January 2, 1990 produced the...
Character, mass, distribution, and origin of tephra-fall deposits of the 1989-1990 eruption of redoubt volcano, south-central Alaska
W. E. Scott, R. G. McGimsey
1994, Journal of Volcanology and Geothermal Research (62) 251-272
The 1989-1990 eruption of Redoubt Volcano spawned about 20 areally significant tephra-fall deposits between December 14, 1989 and April 26, 1990. Tephra plumes rose to altitudes of 7 to more than 10 km and were carried mainly northward and eastward by prevailing winds, where they substantially impacted air travel, commerce,...

1994, Journal of Volcanology and Geothermal Research (62) 1-10
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...
Contrasts in Arctic shelf sea-ice regimes and some implications: Beaufort Sea versus Laptev Sea

1994, Marine Geology (119) 215-225
The winter ice-regime of the <80 km wide Alaskan Beaufort Sea shelf is characterized by compression and shearing, resulting in the formation of major grounded pressure ridge systems stabilizing the fast ice on the mid-shelf, and essentially no open-water areas. In contrast,...

Magnitude and frequency of floods in Alaska and conterminous basins of Canada
Stanley H. Jones, Charles B. Fahl
1994, Water-Resources Investigations Report 93-4179
Equations for estimating the magnitude and frequency of floods at ungaged sites on streams in Alaska and conterminous basins of Canada were developed using multipleregression analyses of basin climatic and physical characteristics and peak-flow statistics from 260 gaged locations in Alaska and 72 gaged locations in Canada. Methods are presented...

Overview of environmental and hydrogeologic conditions at McGrath, Alaska
J.M. Dorava
1994, Open-File Report 94-119
The remote village of McGrath along the Kuskokwim River in southwestern Alaska has long cold winters and short summers. The village is located on the flood plain of the Kuskokwim River and obtains drinking water for its 533 residents from the Kuskokwim River. Surface spills and disposal of hazardous materials...
Mineral-resource assessments in Alaska; background information to accompany maps and reports about the geology and undiscovered-mineral-resource potential of the Mount Katmai Quadrangle and adjacent parts of the Naknek and Afognak quadrangles, Alaska Peninsula
J.R. Riehle, S. E. Church, R. L. Detterman, J. W. Miller
1994, Circular 1106
Geologic and geochemical field studies were carded out from 1983 to 1987 in the Mount Katmai l?x2 ? quadrangle and adjoining region, at the northeast end of the Alaska Peninsula. The region is nearly entirely within Katmai National Park and Preserve and has had almost no mineral production, so prior...
Environmental overview and hydrogeologic conditions at Aniak, Alaska
J.M. Dorava
1994, Open-File Report 94-85
The remote Native village of Aniak, on the flood plain of the Kuskokwim River in southwestern Alaska, has long cold winters and short summers that affect both the hydrology of the area and the lifestyle of the residents. Aniak obtains its drinking water from a shallow aquifer in the thick...

Seismic hazards at Kilauea and Mauna Loa volcanoes, Hawaii
F. W. Klein
1994, Open-File Report 94-216
A significant seismic hazard exists in south Hawaii from large tectonic earthquakes that can reach magnitude 8 and intensity XII. This paper quantifies the hazard by estimating the horizontal peak ground acceleration (PGA) in south Hawaii which occurs with a 90% probability of not being exceeded during exposure times from...
Remote sensing and airborne geophysics in the assessment of natural aggregate resources
D. H. Knepper Jr., W. H. Langer, S.H. Miller
1994, Open-File Report 94-158
Natural aggregate made from crushed stone and deposits of sand and gravel is a vital element of the construction industry in the United States. Although natural aggregate is a high volume/low value commodity that is relatively abundant, new sources of aggregate are becoming increasingly difficult to find and develop because of rigid industry...
