Data on ground-water resources of the Spring Mountains area, Toiyabe National Forest, Nevada
William D. Nichols, Louise E. Davis
1979, Open-File Report 79-1638
This report lists data on ground-water levels for 16 wells and discharge for 18 springs in the Spring Mountain area of the Tolyabe National Forest. Water levels in wells ranged from 325 to 519 feet below land surface. The highest spring discharge listed is 107 gallons per minute. In addition,...
Derivation of linearized constitutive equations for plane-strain of an elastic-plastic (strain hardening) material
Arvid M. Johnson
1979, Open-File Report 79-433
The purpose of this report is to derive several of the basic equations for a paper on folding and folding of idealized rock (Johnson, 1979). That paper is based on constitutive equations for an ideal, strain-hardening material defined by Hill (1950, p. 30) and generalized to include Coulomb behavior and...

Nesting ecology of Arctic loons
Margaret R. Petersen
1979, The Wilson Bulletin (91) 608-617
Arctic Loons were studied on the Yukon-Kuskokwim Delta, Alaska, from the time of their arrival in May to their departure in September, in 1974 and 1975. Pairs arrived on breeding ponds as soon as sufficient meltwater was available to allow their take-off and landing. Loons apparently do not initiate nests...
Dispersal and migratory patterns of San Francisco Bay produced herons, egrets, and terns
Robert E. Gill Jr., L. Richard Mewaldt
1979, North American Bird Bander (4) 4-13
San Francisco Bay, California, including its fringing marshes, supports a large and diverse water related avifauna (Grinnell and Wythe 19271 Sibley 1952, Gill 1973, 1977). Certain of man's alterations of the Bay's shallower wetlands have resulted in increased habitat diversity which has allowed colonization by several species of birds including...
Pomarine jaeger preys on adult black-legged kittiwake
George J. Divoky, Karen L. Oakley, H.R. Huber
1979, The Wilson Bulletin (91) 329-329
On 5 June 1977, while on a cruise in the decomposing pack ice in the Bering Sea, we observed a light phase Pomarine Jaeger (Stercorarius pomarinus) attack, kill and feed on an adult Black-legged Kittiwake (Rissa tridactyla), 1 of approximately 10 individuals within 20 m of the ship's stern. We...
Tufted Puffins nesting in estuarine habitat
Robert E. Gill Jr., Gerald A. Sanger
1979, The Auk (96) 792-794
The Tufted Puffin (Lunda cirrhata) apparently has the most extensive breeding distribution of any North Pacific seabird, extending in the western North Pacific from Hokkaido to the north Chukotsk Peninsula on the Chukchi Sea, and in North America from Cape Lisburne on the Chukchi Sea, south to the Farallon Islands...
Electrical measurements as stress-strain monitors
T. R. Madden
1979, Earthquake Information Bulletin (USGS) (11) 4-8
Many of the measurements of phyiscal properties being made in earthquake prediction studies are based on the premise that these properties are influenced by stresses and strains, especially so near the failure point. Electrical properties of rocks are controlled by the fluid in the pores and cracks in the rocks....

The Worldwide Standardized Seismograph Network (WWSSN) is managed by the U.S Geological Survey in Albuquerque, N. Mex. It consists of a global network of seismographs housed in seismic observatories throughout the world. An important recent addition to this network are the Seismic Research Observatories (SRO) which combine a borehole seismometer...
Microearthquake networks and earthquake prediction
W.H.K. Lee, S. W. Steward
1979, Earthquake Information Bulletin (USGS) (11) 192-195
A microearthquake network is a group of highly sensitive seismographic stations designed primarily to record local earthquakes of magnitudes less than 3. Depending on the application, a microearthquake network will consist of several stations or as many as a few hundred . They are usually classified as either permanent or...
The Parkfield prediction experiment
A. Lindh, P. Evans, P. Harsh, G. Buhr
1979, Earthquake Information Bulletin (USGS) (11) 209-213
The San Andreas fault is part of the boundary between the Pacific and North American crustal plates. In California, movements of about 3 centimeters per year are currently taking place along the fault, although plat tectonic models suggest a faster rate of 5 cm/yr may be the average over a...
Monitoring seismic wave velocities in situ

1979, Earthquake Information Bulletin (USGS) (11) 214-220
Beginning in the early 1960's, reports from the Soviet Union described travel-time anomalies of 5 to 20 percent preceding large earthquakes. In the early 970's, similar observations began to be reported outside the U.S.S.R. The most convincing were anomalously low values of the velocity ration, Vp/Vs, before four earthquakes of...
Earthquakes; January-February, 1979
W. J. Person

Earthquake activity during this period was about normal. Deaths from earthquakes were reported from Greece and Guatemala. Three major earthquakes (magnitude 7.0-7.9) occurred in Taiwan, Chile, and Costa Rica. In the United States, the most significant earthquake was a magnitude 5.6 on August 13 in southern California. ...
