Teton Dam flood of June 1976, Newdale quadrangle, Idaho
Herman A. Ray, Howard F. Matthai, Cecil A. Thomas
1976, Hydrologic Atlas 565
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...
Tragedy at Kilauea
D. A. Swanson, R.L. Christiansen
1976, Earthquake Information Bulletin (USGS) (8) 12-17
The following article is a reconstruction of events surrounding the deaths of a party of Hawaiian warriors in 1790 on Kilauea Volcano. It suggests that they were killed by a very hot, ash-free, base-surge cloud that rushed from the volcano. Much more recently than that, in the early morning hours of...
Geologic mapping and earthquakes in southeastern Idaho
L.B. Platt
1976, Earthquake Information Bulletin (USGS) (8) 8-12
On April 14, 1973, a magnitude 4.75 earthquake occurred in Oneida County, Idaho. The intensity of ground motion was too slight to cause damage, and local interest in this event was so slight that it was not even noted in the weekly newspaper, the Idaho Enterprise, published in Malad City, the...
Earthquakes, October 1975
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 26-27
October was an active month seismically, although there were no damaging earthquakes in the United States. Several States experienced earthquakes that were felt sharply. There were four major earthquakes in other parts of the world, including a magntidue 7.4 in the Philippine Islands that killed on person. ...
Earthquakes, November-December 1975
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 26-29
There were three significant earthquakes during the last 2 months of the year. Two major earthquakes, both magnitude 7.2 occurred, bringing the final major earthquake total for the year to 13, somewhat below the annual average which is about 18. One great earthquake (8.0 and above) per year is average....
Earthquakes; January-March 1976
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 24-27
The year 1976 started out quite active, seismically. Four major earthquakes occurred in different parts of the world during the first 3 months of the year. Three earthquakes rattled the western rim of the Pacific Ocean from the Kuril Islands to the Kermadec Islands. The fourth major earthquake struck Guatemala,...
The 7.2 magnitude earthquake, November 1975, Island of Hawaii
1976, Earthquake Information Bulletin (USGS)
The largest earthquake in over a century struck Hawaii the morning of November 29, 1975, at 4:48 AM HST. The earthquake was of magnitude 7.2 on the Richter scale. It was centered about 5 km beneath the Kalapana area on the southeastern coast of Hawaii, the largest island of the Hawaiian...
Earthquakes, April-May 1976
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 28-30
This was an active period, seismically speaking, with four major earthquakes and a number of strong earthquakes in many parts of the world. Northern Italy experienced one of its most destructive earthquakes in many years. Ecuador suffered fatalities and damage from a strong quake. Uzbek SSR was struck by two...
Is there a periodicity in the occurrence of earthquakes?
R.N. Hunter
1976, Earthquake Information Bulletin (USGS) (8) 4-7
Various periodicities have been suspected in earthquake activity, but none has yet been proved. In his classic text on seismology, K.E Bullen remarked that small but discernable "trigger" forces, such as tidal effects, temperature changes or barometric changes, have been thought to act as "last straw" phenomena when the earthquake...
Earthquake at 40 feet
G. J. Miller
1976, Earthquake Information Bulletin (USGS) (8) 24-25
The earthquake that struck the island of Guam on November 1, 1975, at 11:17 a.m had many unique aspects-not the least of which was the experience of an earthquake of 6.25 Richter magnitude while at 40 feet. My wife Bonnie, a fellow diver, Greg Guzman, and I were diving at...

A study of alternative schemes for extrapolation of secular variation at observatories
L.R. Alldredge
1976, Physics of the Earth and Planetary Interiors (11)
The geomagnetic secular variation is not well known. This limits the useful life of geomagnetic models. The secular variation is usually assumed to be linear with time. It is found that attenative schemes that employ quasiperiodic variations from internal and external sources can improve the extrapolation of secular variation at...
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...

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...

Mixing of carbonate waters
T.M.L. Wigley, Niel Plummer
1976, Geochimica et Cosmochimica Acta (40) 989-995
When mineral solutions of different compositions are mixed, the molalities and activities of individual ions in the mixture are often non-linear functions of their end-member values. This non-linearity is particularly significant in determining mineral saturation levels. Mixtures of saturated solutions may be either...
Optimum level of dietary biotin for growth, feed utilization, and swimming stamina of fingerling lake trout (Salvelinus namaycush)
H. A. Poston
1976, Journal of the Fisheries Research Board of Canada (33) 1803-1806
Triplicate lots of fingerling lake trout (Salvelinus namaycush) held at 9 C for 20 wk were fed a semipurified basal diet supplemented with 1% spray-dried egg white or d-biotin at concentrations of 0.1, 0.5, 1.0, or 5.0 ppm. Trout fed the basal diet, either alone or with egg white, grew more slowly and...

Infection and mortality in captive wild-trapped canvasback ducks
R. M. Kocan, Matthew C. Perry
1976, Journal of Wildlife Diseases (12) 30-33
Fungal, bacterial and malarial infections, as well as malnutrition caused heavy mortality in a group of wild-trapped canvasbacks (Aythya valisineria) held in 10 × 3 × 2 m open water pens. Deaths occurred between 21 and 158 days after confinement and were associated...
Morphology of androgenetic and gynogenetic grass carp, Ctenopharyngodon idella (Valenciennes)
J.C. Stanley, D.E. Schultz
1976, Journal of Fish Biology (9) 523-528
Crosses between female carp x male grass carp resulted in androgenetic grass carp and hybrids. Fertilizing grass carp eggs with carp milt that had been irradiated with ultraviolet light for 15 min at 1.0 mW/cm2 produced gynogenetic grass carp. We compared the morphology of experimental progeny with that of the parental...
The national coal-resources data system of the U.S. geological survey
M.D. Carter
1976, Computers & Geosciences (2) 331-340
The National Coal Resources Data System (NCRDS) was designed by the U.S. Geological Survey (USGS) to meet the increasing demands for rapid retrieval of information on coal location, quantity, quality, and accessibility. An interactive conversational query system devised by the USGS retrieves information from the data bank through a standard...
