Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, August 1974 and chemical monitoring from July 1972 to June 1974
Wilbur C. Ballance, William Thordarson
1976, Report
Radiochemical data from the Arnchitka Island study area were obtained from water samples collected by the U.S. Geological Survey during August 1974. Tritium determinations were made on 18 samples, and gross alpha and gross beta/ gamma determinations were made on 12 samples. No appreciable differences were found between the data...

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...
Atomic absorption spectrometric determination of copper, zinc, and lead in geological materials
R. F. Sanzolone, T. T. Chao
1976, Analytica Chimica Acta (86) 163-168
An atomic absorption spectrometric method is described for the determination of copper, zinc, and lead in geological materials. The sample is digested with HF—HCl—H2O2; the final solution for analysis is in 10 % (v/v) HCl. Copper and zinc are determined directly by aspirating the solution into an air—acetylene flame. A...

1976, Earthquake Information Bulletin (USGS) (8) 21-25
Hisotrically active volcanoes in the conterminous United States are restricted to the Cascade Range and extend to the Cascade Range and extend from Mount Baker near the Canadian border to Lassen Peak in northern California. Since 1800 A.D, most eruptive activity has been on a relatively small scale and has...

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...
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,...
Earthquakes June-July 1976
W. J. Person
1976, Earthquake Information Bulletin (USGS) (8) 31-33
This was a seismically active period, with one great earthquake, four major earthquakes, and several strong shocks worldwide. Many persons were killed and thousands were injured in three separate events-in West Irian (west New Guinea), in Bali, Indonesia, and in northeastern China. A great earthquake (one with a Richter magnitude 8.0...
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, 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. ...
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 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...
The Talas-Fergana Fault, Kirghiz and Kazakh, USSR
R. E. Wallace

The great Talas-Fergana fault transects the Soviet republic of Kirghiz in Soviet Central Asia and extends southeastward into China and northwestward into Kazakh SSR (figs. 1 and 2). This great rupture in the Earth's crust rivals the San Andreas fault in California; it is long (approximately 900 kilometers), complex, and...
