1995, Open-File Report 95-271
During 1994, the Alaska Volcano Observatory (AVO) responded to eruptions, possible eruptions, or false alarms at nine volcanic centers-- Mount Sanford, Iliamna, the Katmai group, Kupreanof, Mount Veniaminof, Shishaldin, Makushin, Mount Cleveland and Kanaga (table 1). Of these volcanoes, AVO has a real time, continuously recording seismic network only at...

Application of surface geophysical techniques in a study of the geomorphology of the lower Copper River, Alaska
T. P. Brabets
1995, Water-Resources Investigations Report 94-4165
As part of a geomorphology study of the lower Copper River, three surface geophysical techniques were tested for their ability to detect infilled scour holes at bridge piers, old river channels, and subbottom deposits in a glacier-formed lake. The methods were (1) ground-penetrating radar, (2) continuous seismic reflection using a...
A compilation of sulfur dioxide and carbon dioxide emission-rate data from Cook Inlet volcanoes (Redoubt, Spurr, Iliamna, and Augustine), Alaska during the period from 1990 to 1994
Michael P. Doukas
1995, Open-File Report 95-55
Airborne sulfur dioxide (SO2) gas sampling of the Cook Inlet volcanoes (Mt. Spurr, Redoubt, Iliamna, and Augustine) began in 1986 when several measurements were carried out at Augustine volcano during the eruption of 1986 (Rose and others, 1988). More systematic monitoring for SO2 began in March 1990 and for carbon...

This report summarizes data acquired from 1990 to 1994 for the gas-hydrate portion of the USGS project 'Permafrost and gas hydrate as possible sources of methane' of the USGS Global Change and Climate History program. The objective of this project has been to test the hypothesis that gas hydrate deposits...

Geochemical data of fumarolically altered rocks, Valley of Ten Thousand Smokes, Alaska
Terry E. Keith
1995, Open-File Report 95-47
Samples from a fossil fumarole originating in the 1912 ash-flow tuffin the Valley of Ten Thousand Smokes have been analyzed to ascertain chemical changes resulting from high-temperature fumarolic alteration and subsequent cooling and weathering of the protolith. Samples of the underlying, dominantly leached, dacite-rich portion of the ash-flow tuff adjacent...
