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...
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...

1976, Earthquake Information Bulletin (USGS) (8) 31-32
Only three shocks (intensity V or greater, Modified Moercalli Scale) have centered in Rhode Island, although several earthquakes in New England and the St.Lawerence Valley have been felt in the State....
How did the 1906 San Francisco earthquake occur?
W. Thatcher
1976, Earthquake Information Bulletin (USGS) (8) 8-13
The 1906 earthquake in San Francisco was of magnitude 8.3 and was the most destructive in the history of the United States. Because this part of California is now much more heavily populated, intense studies have been made of the 1906 earthquake in an effort to understand how it occurred...
Earthquake history of South Carolina
C. A. von Hake
1976, Earthquake Information Bulletin (USGS) (8) 34-38
An estimated $23 million damage was caused by one of the great earthquakes in United States history in 1886. Charleston, S.C, and nearby cities suffered most of the damage, although points as far as 160 km away were strongly shaken. Many of the 20 earthquakes of intensity V or greater...
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...
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...
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...
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...

The San Francisco cow; did she or didn’t she?
M. Hill
1976, Earthquake Information Bulletin (USGS) (8) 19-23
No one has suggested that Mr. Shafter's nameless cow was the cause of the 1906 earthquake, but she has been the source of as persistent a rumor as Mrs. Murphy's Chicago cow. Since 1906, "the cow that fell in the crack" has been a favorite subject of humorous speculation. large...
Earthquake watch
M. Hill
1976, Earthquake Information Bulletin (USGS) (8) 10-11
When the time comes that earthquakes can be predicted accurately, what shall we do with the knowledge? This was the theme of a November 1975 conference on earthquake warning and response held in San Francisco called by Assistant Secretary of the Interior Jack W. Carlson. Invited were officials of State...
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....

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...

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, 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...
A revised “earthquake report” questionnaire
C. Stover, G. Reagor, R. Simon
1976, Seismological Research Letters (8) 18-22
The revised “Earthquake Report” questionnaire introduced here is designed to restrict the replies on the effects of earthquakes as closely as possible to a set of effects that can be evaluated by use of a computer program. Differences in intensity resulting from evaluation by different individuals using their own qualitative...
Monitoring Mount Baker Volcano
S. D. Malone, D. Frank
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...

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...

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...
