The Lice, Turkey, earthquake of September 6, 1975; a preliminary engineering investigation
P. I. Yanev
1976, Earthquake Information Bulletin (USGS) (8) 4-9
The Fifth European Conference on Earthquake Engineering was held on September 22 through 25 in Istanbul, Turkey. The opening speech by the Honorable H. E. Nurettin Ok, Minister of Reconstruction and Resettlement of Turkey, introduced the several hundred delegates to the realities of earthquake hazards in Turkey:...
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...
The sound of an earthquake
D.P. Hill
1976, Earthquake Information Bulletin (USGS) (8) 15-18
Historical accounts of earthquakes often include references to sounds which accompany earthquakes. ...
Earthquake history of Oregon
C. A. von Hake
1976, Earthquake Information Bulletin (USGS) (8) 30-33
Although situated between two States (California and Washington) that have has many violent earthquakes, Oregon is noticeably less active seismically. the greatest damage experienced resulted from a major shock near Olympia, Wash., in 1949. During the short history record available (since 1841), 34 earthquakes of intensity V, Modified Mercalli Scale,...
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. ...
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...
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...
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 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...
Simulation of streamflow of Flambeau River at Park Falls, Wisconsin to define low-flow characteristics
William R. Krug
1976, Water-Resources Investigations Report 76-116
Daily streamflows of the Flambeau River at Park Falls, Wisconsin , were simulated for a 31-year period. Streamflow was simulated using a streamflow-routing model. These simulated daily flows were analyzed for summer (June 1-October 31) low-flow frequency. The resultant 7-day, 10-year summer low flow is 260 cubic feet per second....
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...
Map showing ground-water conditions in the Aravaipa Valley area, Graham and Pinal Counties, Arizona-1975
J. A. Gould, R. P. Wilson
1976, Water-Resources Investigations Report 76-107
This hydrologic map of the Aravaipa Valley area includes about 500 sq mi in southeastern Arizona. Development of the ground-water resources is small, and pumpage is estimated to be less than 3,000 acre-ft annually for irrigation, livestock, and domestic uses. Hydrographs of the water level in selected wells show no...
Oroville earthquakes: Normal faulting in the Sierra Nevada foothills
C. G. Bufe, F.W. Lester, K.M. Lahr, J.C. Lahr, L. C. Seekins, Thomas C. Hanks
1976, Science (192) 72-74
Aftershocks of the Oroville, California, earthquake of 1 August 1975 define a 16- by 12-kilometer fault plane striking north-south and dipping 60 degrees to the west to a depth of 10 kilometers. Focal mechanisms from P-wave first motions indicate normal faulting with the western, Great Valley side downdropped relative to...
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...
