Minerals, lands, and geology for the common defence and general welfare, Volume 1, Before 1879 : A history of public lands, federal science and mapping policy, and development of mineral resources in the United States
Mary C. Rabbitt
1979, Book
This volume, the first of a four-volume study, is concerned with events in the United States before the establishment of the U.S. Geological Survey, during the years in which geology evolved as a science and began to influence economic development and national policy. Subsequent volumes continue the story but focus...
Trees as indicators of past movements on the San Andreas Fault
R. E. Wallace, Valmore C. LaMarche Jr.
1979, Earthquake Information Bulletin (USGS) (11) 127-131
Trees are sources of information about fault movements that have occurred before the earliest historical reports. This kind of evidence can be used to improve estimates of when earthquakes will recur on faults known to be seismically active and to identify active faults that have no record of movement during...

The months of September and October were somewhat quiet seismically speaking. One major earthquake, magnitude (M) 7.7 occurred in Iran on September 16. In Germany, a magntidue 5.0 earthquake caused damage and considerable alarm to many people in parts of that country. In the United States, the largest earthquake occurred...

1979, Earthquake Information Bulletin (USGS) (11) 236-238
The months of May and June were somewhat quiet, seismically speaking. There was one major earthquake in the South Pacific on MAy 1. The most destructive earthquake, causing loss of life, was in Indonesia on May 30. In the United States, the largest earthquakes were in Alaska but caused no damage....
Earthquakes; March-April, 1979
W. J. Person
1979, Earthquake Information Bulletin (USGS) (11) 183-186
This was a moderately active period, seismically speaking. Three major earthquakes having magnitudes (M) ranging from 7.0 to 7.9 to only one major quake during the first 2 months of the year. Major earthquakes struck in Mexico, Indonesia, and Yugoslavia. The Yugoslavian earthquake caused considerable damage and loss of life. In...
Earthquakes; July-August, 1978
W. J. Person
1979, Earthquake Information Bulletin (USGS) (11) 26-29
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. ...

W. J. Person
1979, Earthquake Information Bulletin (USGS) (11) 143-147
The first major earthquake (magnitude 7.0 to 7.9) of the year struck in southeastern Alaska in a sparsely populated area on February 28. On January 16, Iran experienced the first destructive earthquake of the year causing a number of casualties and considerable damage. Peru was hit by a destructive earthquake...
Computers at the Albuquerque Seismological Laboratory
J. Hoffman
1979, Earthquake Information Bulletin (USGS) (11) 138-140
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...
Potentials and limits for the use of ozone as a fish disease control agent
Gary A. Wedemeyer, Nancy C. Nelson, T. Yasutake
1979, Ozone: Science and Engineering (1) 295-318
Ozone and chlorine inactivation curves were determined in three types of freshwater at 20 C for the destruction of the fish pathogens Aeromonas salmonicida the etiologic agent of furunculosis, and Yersinia ruckeri the enteric redmouth bacterium (ERM). Ozone and chlorine inactivation curves were also obtained in the same water types at 10 C for...
Physiological and biochemical aspects of ozone toxicity to rainbow trout (Salmo gairdneri)
Gary A. Wedemeyer, Nancy C. Nelson, William T. Yasutake
1979, Journal of the Fisheries Research Board of Canada (36) 605-614
An acute toxicity curve for dissolved ozone (O3) in soft water at 10 °C, using 10–13-cm rainbow trout (Salmo gairdneri) as the test species was calculated. The 96-h LC50 (95%, confidence interval) was 9.3 (8.1–10.6) μg/L. The lethal threshold level was about 8 μg/L mandating that a conservative margin of safety be...
Artificial transmission to and susceptibility of Puget Sound fish to viral erythrocytic necrosis (VEN)
John R. MacMillian, Dan Mulcahy
1979, Journal of the Fisheries Research Board of Canada (36) 1097-1101
In Puget Sound, Wash., the incidence of viral erythrocytic necrosis (VEN) varied geographically from 0 to 17% in chum salmon (Oncorhynchus keta) and from 4 to 59% in Pacific herring (Clupea harengus pallasi). The disease was experimentally transmitted by intraperitoneal injection to chum, pink (O. gorbuscha), coho (O. kisutch), chinook (O. tshawytscha), sockeye...
New host and geographical records for the leech Acanthobdella peledina Grube 1851 (Hirudinea, Acanthobdellidae)
A. K. Hauck, Michael J. Fallon, Carl V. Burger
1979, Journal of Parasitology (65) 989-989
A total of four leeches (Acanthobdella peledina), parasitizing four specimens of the least cisco (Coregonus sardinella), were found during July and August 1977. The hosts and parasites were collected during a fishery survey by the U.S. Fish and Wildlife Service in the North Slope waters of Naval Petroleum Reserve, Alaska....
Monitoring seismic wave velocities in situ
T.V. McEvilly, R. Clymer
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...
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....

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...
Microearthquake networks and earthquake prediction
W.H.K. Lee, S. W. Steward

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 Survey’s first venture into seismology
M. C. Rabbitt
1979, Earthquake Information Bulletin (USGS) (11) 50-52
The occurrence of two small but widely felt earthquakes in the Eastern United States in 1884 led an editor of the research journal Science to suggest, in the October 3 issue of the magazine, that an "earthquake club" be formed. Its purpose was so that observers and students of "this branch...
