A probabilistic estimate of maximum acceleration in rock in the contiguous United States
Sylvester Theodore Algermissen, David M. Perkins
1976, Open-File Report 76-416
This paper presents a probabilistic estimate of the maximum ground acceleration to be expected from earthquakes occurring in the contiguous United States. It is based primarily upon the historic seismic record which ranges from very incomplete before 1930 to moderately complete after 1960. Geologic data, primarily distribution of faults, have...
Handbook for USGS Central California Microearthquake Network, 1969-1975
Stephen Travis Houck, J.D. Guerrero, A.E. Miller, W.H. Lee
1976, Open-File Report 76-282
The Central California Microearthquake Network of the United States Geological Survey furnishes a large volume of earthquake data concerning seismic activity in Central California. It is our hope that this report will render these data more accessible. We will try to accomplish this by presenting tables dealing with station location,...
Time-of-travel studies, Susquehanna River, Binghamton, New York, to Clarks Ferry, Pennsylvania
C.D. Kauffman, J.T. Armbruster, Andrew Voytik
1976, Open-File Report 76-247
Results of time-of-travel studies are presented in both tabular and graphical form for several flow conditions in the Susquehanna River from Binghamton, N.Y., to Clarks Ferry, Pa. This reach is approximately 240 miles (386 kilometres) long, measured along the center of the channel, and has a drainage area of about...
Numerical modeling of subsurface radioactive solute transport from waste seepage ponds at the Idaho National Engineering Laboratory
John B. Robertson
1976, Open-File Report 76-717
Aqueous chemical and low-level radioactive effluents have been disposed to seepage ponds since 1952 at the Idaho National Engineering Laboratory. The solutions percolate toward the Snake River Plain aquifer (135 m below) through interlayered basalts and unconsolidated sediments and an extensive zone of ground water perched on a sedimentary layer...
In-situ measurements of seismic velocities in the San Francisco Bay region...Part II
James F. Gibbs, Thomas E. Fumal, Roger D. Borcherdt
1976, Open-File Report 76-731
Seismic wave velocities (compressional and shear) are important parameters for determining the seismic response characteristics of various geologic units when subjected to strong earthquake ground shaking.Seismic velocities of various units often show a strong correlation with the amounts of damage following large earthquakes and have been used as a basis...
Guide to the availability of hydrologic data, Greater Pittsburgh region, Pennsylvania
Robert M. Beall
1976, Open-File Report 76-352
A great variety of hydrologic data are collected by many governmental agencies and other entities for diverse purposes. Some of the data are compiled and reported in readily available, widely known publications; some are not. Continuing requests for information on the locations of data collection sites and on the sources...
Analysis of seismograms from a downhole array in sediments near San Francisco Bay
William B. Joyner, Richard E. Warrick, Adolph A. Oliver III
1976, Open-File Report 76-296
A four-level downhole array of three-component instruments was established on the southwest shore of San Francisco Bay to monitor the effect of the sediments on low-amplitude seismic ground motion. The deepest instrument is at a depth of 186 meters, two meters below the top of the Franciscan bedrock. Earthquake data...
Collection, chemical analysis, and evaluation of coal samples in 1975
Vernon Emanuel Swanson, J.H. Medlin, J. R. Hatch, S.L. Coleman, G.H. Wood Jr., S.D. Woodruff, R.T. Hildebrand
1976, Open-File Report 76-468
During 1975, the U.S. Geological Survey, in cooperation with other Federal and State agencies, university groups, and private companies, continued its program to augment and refine information on the composition of coal in the United States. This report includes all analytical data on 799 channel samples of coal beds from...
Simulation procedure for modeling transient water table and artesian stress and response
J.E. Reed, M. S. Bedinger, J. E. Terry
1976, Open-File Report 76-792
The series of computer programs described in this report were designed specifically to model the ground-water regime in sufficient detail to determine the effects of the imposition of various types of stress upon the system, and to display the results in a convenient manner during calibration and when presenting projected...
Integration of geological remote-sensing techniques in subsurface analysis
James V. Taranik, Charles M. Trautwein
1976, Open-File Report 76-402
Geological remote sensing is defined as the study of the Earth utilizing electromagnetic radiation which is either reflected or emitted from its surface in wavelengths ranging from 0.3 micrometre to 3 metres. The natural surface of the Earth is composed of a diversified combination of surface cover types, and geologists...
Empirical transfer functions for stations in the Central California seismological network
W. H. Bakun, Jay Dratler
1976, Open-File Report 76-259
A sequence of calibration signals composed of a station identification code, a transient from the release of the seismometer mass at rest from a known displacement from the equilibrium position, and a transient from a known step in voltage to the amplifier input are generated by the automatic daily calibration...
