Effects of local geology on ground motion in the San Francisco Bay region, California: A continued study
James F. Gibbs, Roger D. Borcherdt
1974, Open-File Report 74-222
Measurements of ground motion generated by nuclear explosions in Nevada have been completed for 99 locations in the San Francisco Bay region, California. The seismograms, Fourier amplitude spectra, spectral amplification curves for the signal, and the Fourier amplitude spectra of the seismic noise are presented for 60 locations. Analog amplifications,...
Geology of the Zwedru Quadrangle, Liberia
Eric R. Force, Helen Marie Beikman
1974, Open-File Report 74-307
As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period...
Summary appraisals of the nation's ground-water resources – Upper Colorado region
Don Price, Ted Arnow
1974, Professional Paper 813-C
The Upper Colorado Region covers about 113,500 square miles (293,965 km2) in parts of Arizona, Colorado, New Mexico, Utah, and Wyoming. Drainage from about 97 percent of the region is to the Colorado River. About 60 percent of the land is owned or administered by the Federal Government, and another...
Hydrologic Unit Map -- 1974, Minnesota
Water Resources Division, U.S. Geological Survey
1974, Hydrologic Unit 23
This map and accompanying table show Hydrologic Units that are basically hydrographic in nature.  The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Information on Water Data (1966-72).   ...
Atlantic OCS resource and leasing potential
Richard Q. Foote, Robert E. Mattick, John Charles Behrendt
1974, Open-File Report 74-348
Thick marine sedimentary sections and geologic structures favorable for the accumulation of petroleum are indicated in Georges Bank basin, the Baltimore Canyon trough, and the Southeast Georgia embayment. Undiscovered recoverable resources of petroleum on the Atlantic OCS are estimated to be 10 billion to 20 billion barrels of oil and...
A program to compute aquifer-response coefficients
Thomas Maddock
1974, Open-File Report 75-612
An alternating direction technique is used to solve finite difference equations approximating the flow of water in an aquifer. The solutions produce response coefficients relating pumping from wells to drawdowns within those wells. The product of the response coefficient with the pumping values produces a linear algebraic technological function that...
South Carolina seismic program
Arthur C. Tarr, Kenneth W. King
1974, Open-File Report 74-58
The principal objectives of the South Carolina Seismic Program are to: (1) provide essential high-quality raw seismic data for earthquakes in South Carolina; (2) compute accurate estimates of event and source parameters; (3) provide a catalog of events and source parameters that will be used in further evaluation of seismic...
Seismic investigations in Wyoming as part of the Wagon Wheel definition studies
Kenneth C. Bayer, Geraldine M. Wuollet
1974, Open-File Report 74-30
As part of the Wagon Wheel definition studies, seismic investigations were conducted in Wyoming by personnel of the United States Geological Survey, Las Vegas, Nevada. From March 22, 1973 to February 22, 1974, a seismograph station recorded seismic activity at five different areas in the vicinity of the proposed Project Wagon Wheel location in...
Geology of the Bopolu Quadrangle, Liberia
Roberts Manning Wallace
1974, Open-File Report 74-302
As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period...
Development and evaluation of a prototype global volcanic surveillance system utilizing the ERTS-1 satellite data collection system
Peter L. Ward, Elliot T. Endo, David H. Harlow, Rex Allen, Dan Marquez, Jerry P. Eaton
1974, Open-File Report 74-124
The ERTS Data Collection System makes it feasible for the first time to monitor the level of activity at widely separated volcanoes and to relay these data rapidly to one central office for analysis. This capability opens a new era in volcanology where the hundreds of normally quiescent but potentially...
Geology of the Harper Quadrangle, Liberia
M. R. Brock, A.H. Chidester, M.G.W. Baker
1974, Open-File Report 74-310
As part of a program undertaken cooperatively by the Liberian Geological Survey (LGS) and the U. S. Geological Survey (USGS), under the sponsorship of the Government of Liberia and the Agency for International Development, U. S. Department of State, Liberia was mapped by geologic and geophysical methods during the period...
Economic geology of the Isla de Mona Quadrangle, Puerto Rico
Reginald Peter Briggs
1974, Open-File Report 74-226
Limiting this tableland In the northern part of Isla de Mona are sheer sea cliffs chiefly exposing the Isla de Mona Dolomite. Around the southern part of the island are Irregular cliffs and steep slopes that chiefly expose the Lirio Limestone. The structure of Isla de Mona consists of two...
