Rockfall seismicity correlation with field observations, Makaopuhi Crater, Kilauea Volcano, Hawaii
Robert I. Tilling, Robert Y. Koyanagi, Robin T. Holcomb
1975, Journal of Research of the U.S. Geological Survey (3) 345-361
During August 7-13, 1972, intense and sustained rockfall activity occurred in Makaopuhi Crater on the east-rift zone of Kilauea Volcano. In a 4-day period (August 7-10), approximately 270,000 m3 of rockfall debris accumulated in Makaopuhi's west pit, representing a total kinetic energy release of about 101B ergs. Because the rockfalls...
The influence of late Cenozoic stratigraphy on distribution of impoundment-related seismicity at Lake Mead, Nevada-Arizona
R. Ernest Anderson, R. L. Laney
1975, Journal of Research of the U.S. Geological Survey (3) 337-343
At Lake Mead, contrasts in permeability of upper Cenozoic sediments show a better correlation with irregularly distributed impoundment-related seismicity than do contrasts in structure. An evaluation of structures developed during the late Cenozoic fails to explain the erratic distribution of seismicity. An evaluation of the late Cenozoic stratigraphy, however, shows...
Widespread late glacial and postglacial tephra deposits from Mount St. Helens Volcano, Washington
Donal R. Mullineaux, Jack H. Hyde, Meyer Rubin
1975, Journal of Research of the U.S. Geological Survey (3) 329-335
Pumice layers composing four different groups of tephra beds (termed "sets"), whose stratigraphy, age, and trend away from Mount St. Helens are fairly well known, are potentially valuable stratigraphic markers in the northwestern United States and adjacent parts of Canada. All four tephra sets are less than about 18,000 yr...

Larry F. Land
1975, Open-File Report 75-74
Land in southeast Palm Beach County is undergoing a large-scale change in use, from agricultural to residential. To accommodate residential use, a proposal has been made by developers to the Board of the Lake Worth Drainage District to lower the canal stages in the interior part of the area undergoing...

Lehigh Acres, a residential community with a population of about 13,500 and comprising an area of about 94 square miles (243 square kilometres) in the eastern part of Lee County, has been under development since 1954. Prior to development the area was poorly drained. By 1974, more than 150 miles...
Recurrent geothermally induced debris avalanches on Boulder Glacier, Mount Baker, Washington
David Frank, Austin Post, Jules D. Friedman
1975, Journal of Research of the U.S. Geological Survey (3) 77-87
Avalanches of snow, firn and hydrothermally altered rock and mud have been released six times since 1958 from Sherman Peak, part of the crater rim south of the main summit of Mount Baker, Wash. The avalanches traveled nearly identical paths 2.0-2.6 km down Boulder Glacier on the east slope of...

Dynamics of turbidity plumes in Lake Ontario
Edward J. Pluhowski
1975, Open-File Report 75-249
Large-turbidity features along the 275-kilometre long south shore of Lake Ontario were analyzed using LANDSAT-1 images. The ESIAC system developed by the Stanford Research Institute, was used to obtain enlargements and false-color renditions of turbidity plumes. After projection on a video screen, individual turbidity features were analyzed, mapped, and photographed.The...

Robert O. Castle, Jack P. Church, Michael R. Elliot, Nancy L. Morrison
1975, Tectonophysics (29) 127-140
Comparative elevations referred chiefly to a tidal bench mark with a history of relatively positive movement show that much of the Transverse Ranges of southern California sustained major changes in elevation both before and in association with the ML 6.4 San Fernando earthquake of February 9, 1971. Preseismic changes in...

Geothermal significance of eastward increase in age of upper Cenozoic rhyolitic domes in southeastern Oregon
Norman S. MacLeod, George Walton Walker, Edwin H. McKee
1975, Open-File Report 75-348
Rhyolitic domes, flows, and ash-flow tuffs of Miocene to Holocene age form an important part of the thick sequence of Cenozoic volcanic rocks that cover southeastern Oregon east of the Cascade Range.

1974, Water Supply Bulletin 40
Since 1952 water diverted from the Columbia River at Grand Coulee Dam has been used to irrigate parts of the Columbia Basin Irrigation Project area in eastern Washington, and as a result ground-water levels generally have risen in the area. The rapid increases in ground-water inflow, outflow, and storage from...
