Reconnaissance geochemical studies in the Bristol Bay, Ugashik, and Karluk quadrangles, Alaska: A section in The United States Geological Survey in Alaska: Accomplishments during 1980
David E. Detra, Robert L. Detterman, Dennis P. Cox, Frederic H. Wilson, Ted G. Theodore
1982, Circular 844
Geochemical reconnaissance studies in the Bristol Bay, Ugashik, and Karluk quadrangles were completed with collection and analyses of more than 1,200 stream-sediment and heavy mineral-concentrate samples during 1979 and 1980. At least two areas of possible metallic mineral occurrence have been delineated by results of the analyses, geologic fieldwork, and...
Apparent episodicity of magmatic activity based on radiometric age determination: A section in The United States Geological Survey in Alaska: Accomplishments during 1980
Frederic H. Wilson, Nora B. Shew
1982, Circular 844
Results of recent potassium-argon age studies in the Chignik region, Alaska, (Wilson, 1980; Wilson and others, 1982) have suggested a distinct episodicity in igneous activity during Tertiary time. To date work on the Aleutian magmatic arc indicates that plutonic activity took place along the present outer Pacific margin and in...
Aeromagnetic survey of the Chignik and Sutwik Island quadrangles: A section in The United States Geological Survey in Alaska: Accomplishments during 1980
James E. Case, Dennis P. Cox, David E. Detra, Robert L. Detterman, Frederic H. Wilson
1982, Circular 844
The recently completed aeromagnetic survey of the Chignik and Sutwik Island quadrangles, on the Alaska Peninsula, is one of the most detailed systematic surveys ever made across a modern "volcanic arc" setting where both Holocene volcanic edifices and older volcanic centers occur (fig. 54)....
The 1979 Imperial Valley. California, earthquake
Henry Spall, editor(s)
1982, Earthquake Information Bulletin (USGS) (14) 173-179
On October 15, 1979, the largest earthquake in California in the last quarter century occurred on the imperial fault near the international boundary between the United States and Mexico.  The earthquake measured 6.6 on the Richter scale and was felt from Las Vegas, Nevada, to northern Mexico.  Surface movement on...
Utah water use data: Public water supplies, 1981
David Hooper, Richard Schwarting
1982, Utah Division of Water Rights Water-Use Report 4
This publication is the fourth in a series of continuing reports presenting water use data for Utah. The data are collected by the State of Utah, Division of Water Rights, for the National Water Use Information Program. This is a cooperative effort with the U.S. Geological Survey.  Most states contribute...
Utah water use data: Public water supplies, 1980

1982, Utah Division of Water Rights Water-Use Report 3
This publication is the third in a series of continuing reports presenting water use data for Utah. The data are collected by the State of Utah, Division of Water Rights, for the National Water Use Information Program. This is a cooperative effort with the U.S. Geological Survey.  Most states contribute...
Magnitude and intensity: Measures of earthquake size and severity
Henry Spall, editor(s)
1982, Earthquake Information Bulletin (USGS) (14) 209-219
Earthquakes can be measured in terms of either the amount of energy they release (magnitude) or the degree of ground shaking they cause at a particular locality (intensity).  Although magnitude and intensity are basically different measures of an earthquake, they are frequently confused by the public and new reports of...
Southern California's last great earthquake and clues about the next one
Henry Spall, editor(s)
1982, Earthquake Information Bulletin (USGS) (14) 134-139
This year marked the 125th anniversary of the great Fort Tejon, California, earthquake of January 9. 1857.  By digging large trench along the segment of the San Andreas fault that broke near Pallett Creek and by studying contemporary records, Kerry Sieh of the California Institute of Technology has found evidence...
