Seismicity and faulting attributable to fluid extraction
R. F. Yerkes, R. O. Castle
1976, Engineering Geology (10) 151-167
The association between fluid injection and seismicity has been well documented and widely publicized. Less well known, but probably equally widespread are faulting and shallow seismicity attributable solely to fluid extraction, particularly in association with petroleum production. Two unequivocable examples of seismicity and faulting associated with fluid extraction in the...
The Anderson Reservoir seismic gap - Induced aseismicity?
C. G. Bufe
1976, Engineering Geology (10) 255-262
A persistent 10-km seismicity gap along the Calaveras fault appears to be related to the presence of the Leroy Anderson Reservoir in the Calaveras-Silver Creek fault zones southeast of San Jose, California. A magnitude-4.7 earthquake occurred at a depth of 5 km in the centre of the gap on October...
Teton Dam flood of June 1976, St. Anthony quadrangle, Idaho
Cecil A. Thomas, Herman A. Ray, Howard F. Matthai
1976, Hydrologic Atlas 566
The failure of the Teton Dam caused extreme flooding along the Teton River, Henrys Fork, and Snake River in southeastern Idaho on June 5-8, 1976. No flooding occurred downstream from American Falls Reservoir. The inundated areas and maximum water-surface elevations are shown in a series of 17 hydrologic atlases. The...
Earthquake prediction; fact and fallacy
R.N. Hunter
1976, Earthquake Information Bulletin (USGS) (8) 24-27
Earthquake prediction is a young and growing area in the field of seismology. Only a few years ago, experts in seismology were declaring flatly that it was impossible. Now, some successes have been achieved and more are expected. Within a few years, earthquakes may be predicted as routinely as the...
Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, May 1974
William Thordarson, Wilbur C. Ballance
1976, Report
During May 1974, the U.S. Geological Survey collected water samples from Amchitka Island, Alaska. Tritium determinations were made on 99 water samples, and dissolved gross alpha and gross beta/gamma determinations were made on 34 water samples, No appreciable differences were found between the data obtained in May 1974 and the...
Earthquake history of Pennsylvania
C. A. von Hake
1976, Earthquake Information Bulletin (USGS) (8) 28-31
Record of early earthquakes in Northeastern United States provide limited information on effects in pennsylvania until 1737, 55 years after the first permanent settlement was established. A very severe earthquake that centered in the St.Lawrence River region in 1663 may have been felt in Pennsylvania, but historical accounts are not...
Geothermal energy in the United States; Part II, Assessment of resources
D.L. Williams
1976, Earthquake Information Bulletin (USGS) (8) 18-23
Geothermal energy-from heat deep inside the Earth- is a vast potential source of power. This article is the second part of a series on geothermal energy, the first part of which was in volume 8, number 1, of the Earthquake Information Bulletin (January-February 1976). Part 1 of this series described the...
Submarine geothermal resources
D.L. Williams
1976, Journal of Volcanology and Geothermal Research (1) 85-100
Approximately 20% of the earth's heat loss (or 2 ?? 1012 cal/s) is released through 1% of the earth's surface area and takes the form of hydrothermal discharge from young (Pleistocene or younger) rocks adjacent to active seafloor-spreading centers and submarine volcanic areas. This amount is roughly equivalent to man's...
Upland sandpiper nesting and management in North Dakota
L.M. Kirsch, K.F. Higgins
1976, Wildlife Society Bulletin (4) 16-20
Nests of 195 upland sandpipers (Bartramia longicauda) on the Missouri Coteau of North Dakota generally were well concealed by grassy vegetation which ranged from 15.4-30.8 cm in height. Nest densities ranged from 0.3 per 40.5 ha on annually tilled croplands to 6.8 per 40.5 ha on native grasslands during the...
Duck nesting in fields of undisturbed grass-legume cover
Harold F. Duebbert, J. T. Lokemoen
1976, Journal of Wildlife Management (40) 39-49
A study of dabbling duck (Anatinae) nesting was conducted during 1971-73 on nine 12- to 54-ha Cropland Adjustment Program fields in the prairie pothole region of north-central South Dakota. The tall, dense vegetation was comprised of introduced cool-season grasses and legumes, primarily smooth bromegrass (Bromus inermis), intermediate wheatgrass (Agropyron intermedium),...
The area of influence of an exploratory hole
D.A. Singer, L. J. Drew
1976, Economic Geology (71) 642-647
A method is presented for calculating the area of influence of exploratory drill holes by using the size and shape of resource targets. The solution presented is for elliptical and circular targets, but the method is applicable to any shaped target. The degree to which points have been explored depends...
Prevention and control of viral diseases of salmonids
Donald F. Amend
1976, Journal of the Fisheries Research Board of Canada (33) 1059-1066
Three viral diseases of salmonids are of worldwide concern: infectious pancreatic necrosis (IPN) viral hemorrhagic septicemia (VHS), and infectious hematopoietic necrosis (IHN). Six principal approaches are being used to prevent or control these diseases: 1) preventing contact o the pathogen with the host, 2) environmental manipulation, 3) immunization, 4) chemotherapy,...
Physiological response to hooking stress in hatchery and wild rainbow trout (Salmo gairdneri)
R.S. Wydoski, Gary Wedemeyer, N. C. Nelson
1976, Transactions of the American Fisheries Society (105) 601-606
This study evaluated the physiological response of rainbow trout to hooking stress after being played under standardized conditions (0–5 min) and estimated the time needed for recovery (to 72 h). Plasma osmolality and chloride measurements were used to evaluate osmoregulatory disturbances and gill ion-exchange function, and plasma glucose was used...
Wildlife diseases: philosophical considerations
M. Friend
L.A. Page, editor(s)
1976, Book chapter, Wildlife diseases
Wildlife diseases are studied because of their adverse impact on human health, agriculture, or wildlife conservation. Viewpoints from these three major areas of concern are not always compatible, yet the ecological nature of disease makes it essential that each is recognized and understood. Within wildlife agencies, resistance or apathy toward...
