Seismicity map of the State of Virginia
B.G. Reagor, C. W. Stover, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1257
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. These data have been reexamined which resulted in some...
Reconnaissance of the effect of landfill leachate on the water quality of Marshall Brook, Southwest Harbor, Hancock County, Maine
Bruce P. Hansen
1980, Open-File Report 80-1120
A small stream (2.2 square miles drainage area) receiving leachate from a landfill was studied from August through November 1979 to determine the impact of the leachate on water quality. The presence of un-ionized ammonia, considered toxic to some aquatic vertebrates, was indicated in samples taken from sections of the...
Seismicity map of the State of North Carolina
B.G. Reagor, C. W. Stover, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1224
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. These data have been reexamined which resulted in some...
Preliminary observations of noise spectra at the SRO and ASRO stations
Jon Peterson
1980, Open-File Report 80-992
The seismic noise spectra presented in this report were derived from SRO and ASRO station data for the purpose of evaluating the performance of the seismic instruments. They are also useful for constructing a spectral estimate of earth noise at a quiet site based on noise samples obtained from a...
Quaternary stratigraphic sections with radiocarbon dates, Wiseman Quadrangle, Alaska
Thomas D. Hamilton
1980, Open-File Report 80-791
The Wiseman quadrangle contains a rich stratigraphic record of alluvial, glacial, and periglacial events of the late Quaternary in the south-central Brooks Range. The numerous bluffs along the Koyukuk River and its tributaries expose drift sheets of the late Pleistocene Itkillik I glacial phase (table 1), and outwash and other...
Test and calibration of the Seismic Research Observatory
Jon Peterson, Charles R. Hutt, L. Gary Holcomb
1980, Open-File Report 80-187
The Seismic Research Observatory (SRO) network is generating an important new data base for seismological research. The SRO systems have extended both the range and resolution of seismic measurements beyond the limits of conventional seismographs and the data are recorded in digital format making it convenient to automate processing and...
Correlation of coal beds, coal zones, and key stratigraphic units in the Pennsylvanian rocks of eastern Kentucky
Charles L. Rice, J. Hiram Smith
1980, Miscellaneous Field Studies Map 1188
The Pennsylvanian rocks of the eastern Kentucky coal field unlderlie an area of about 27,000 square kilometers (see index map). Largely because of the size and stratigraphic complexity of the area, Huddle and others (1963, p. 31) divided it into six coal reserve districts (unofficial), utilizing state and county lines...
