Volcanology in Hawaii
R. Decker, B. Decker
1988, Earthquakes & Volcanoes (USGS) (20) 4-30
Polynesians who first inhabited the Hawaiian Islands told in legend about Pele, Goddess of volcanic fires, who migrated from the Island of Kauai to Oahu, then to Maui, and finally to her present home in Kilauea Volcano's Halemaumau Crater on the Island of Hawaii. Geologists today accept this same relative...

1988, Earthquakes & Volcanoes (USGS) (20) 196-198
There were no major earthquakes during the months of May and June. Only one earthquake-related death was reported; this occurred on June 20 in the Philippine Islands. In the United States, three moderate earthquakes were expereinced in California but none crashed deaths or injuries. ...
Forecasting California’s earthquakes
R. A. Kerr
1988, Earthquakes & Volcanoes (USGS) (20) 114-119
The first official earthquake forecast for California emphasizes the broad extent of the hazard and the uncertainties involved in predicting the next quakes. For the first time, researchers have reached to a consensus on the threat of large earthquakes to California, things look no worse for Los Angles than before. It...

Y. Oki, S. Otaka
1988, Earthquakes & Volcanoes (USGS) (20) 224-225
Trees show a record of the great Kanto earthquake of 1923 in Japan. Two minutes before noon on the morning of September 1, 1923, the Great Kanto earthquake occurred with a magnitude of 7.9 in the northern part of Mizukuma in Sagmi Prefecture, Japan. Fires broke out immediately following the earthquake,...

J. A. Allen, D.P. Pimentel, J.P. Lasoie
1988, Forest Ecology and Management (25) 239-254
Information of fuelwood consumption and the local production of wood was collected in two small rural communities in Swaziland. Fuelwood consumption was estimated to be 0.77 t persona??1 yeara??1 in one community (Sigombeni), and 0.63 t persona??1 in the other (Bhekinkhosi). Bhekinkhosi was found to be experiencing a significant fuelwood...
Thermal infrared (2.5- to 13.5-µm) directional hemispherical reflectance of leaves
J.W. Salisbury, N.M. Milton
1988, Photogrammetric Engineering and Remote Sensing (54) 1301-1304
Previous biconical reflectance measurements of 13 different plant species have shown that leaves display spectral signatures in the 8- to 14-??m atmospheric window that vary with species. Directional hemispherical reflectance measurements of six species reported here document the absolute magnitude of such spectral features for the first time. If half...

Estimates of gains and losses for reservoirs on the Snake River from Blackfoot to Milner, Idaho, for selected periods, 1912 to 1983
L.C. Kjelstrom
1988, Water-Resources Investigations Report 87-4063
Croplands in the semiarid central part of the Snake River Plain are dependent on the availability of irrigation water, most of which comes from the Snake River. Allocation of irrigation water from the river requires that gains and losses be determined for American Falls Reservoir, Lake Walcott, and Milner Lake....
Cyclic development of igneous features and their relationship to high-temperature hydrothermal features in the Henderson porphyry molybdenum deposit, Colorado
R.B. Carten, E. P. Geraghty, B.M. Walker
1988, Economic Geology (83) 266-296
The Henderson porphyry molybdenum deposit was formed by the superposition of coupled alteration and mineralization events, of varying intensity and size, that were associated with each of at least 11 intrusions. Deposition of molybdenite was accompanied by time-equivalent silicic and potassic alteration. High-temperature alteration and mineralization are spatially and temporally...
Hydrologic reconnaissance of the Chilkat River basin, Southeast Alaska; with special reference to the Alaska Chilkat Bald Eagle Preserve
E. F. Bugliosi
1988, Water-Resources Investigations Report 88-4023
The Chilkat River Basin of Alaska is characterized by glaciers, highly dissected mountains with steep-gradient streams, and braided rivers in broad, alluvium-filled valleys. Orographic effects and a wide seasonal range in temperature cause variations in the amount and distribution of precipitation, and thus in the resulting runoff and streamflow. Seeps...
Evolution of silicic magma in the upper crust: the mid-Tertiary Latir volcanic field and its cogenetic granitic batholith, northern New Mexico, USA
P. W. Lipman
1988, Transactions of the Royal Society of Edinburgh, Earth Sciences (79) 265-288
Structural and topographic relief along the eastern margin of the Rio Grande rift, northern New Mexico, provides a remarkable cross-section through the 26-Ma Questa caldera and cogenetic volcanic and plutonic rocks of the Latir field. Exposed levels increase in depth from mid-Tertiary depositional surfaces in northern parts of the igneous...
Simulation of three lahars in the Mount St Helens area, Washington using a one-dimensional, unsteady-state streamflow model
Antonius Laenen, R. P. Hansen
1988, Water-Resources Investigations Report 88-4004
A one-dimensional, unsteady-state, open-channel model was used to analytically reproduce three lahar events. Factors contributing to the success of the modeling were: (1) the lahars were confined to a channel, (2) channel roughness was defined by field information, and (3) the volume of the flow remained relatively unchanged for the...

Sr and Nd isotopic variations in ferromanganese crusts from the Central Pacific: Implications for age and source provenance
K. Futa, Z. E. Peterman, J.R. Hein
1988, Geochimica et Cosmochimica Acta (52) 2229-2233
Isotopic analyses of two hydrogenetic ferromanganese (Fe-Mn) crusts from volcanic edifices in the central Pacific Ocean reveal systematic variations in 87Sr86Sr">87Sr86Sr and 143Nd144Nd">143Nd144Nd, with both ratios decreasing as a function of depth into the Fe-Mn crusts. Leaching experiments suggest that Sr...
Fishery research in the Great Lakes using a low-cost remotely operated vehicle
Gregory W. Kennedy, Charles L. Brown, Ray L. Argyle
1988, Conference Paper, Inshore '88 Conference Proceedings
We used a MiniROVER MK II remotely operated vehicle (ROV) to collect ground-truth information on fish and their habitat in the Great Lakes that have traditionally been collected by divers, or with static cameras, or submersibles. The ROV, powered by 4 thrusters and controlled by the pilot at the surface,...

J.R. Evans, J.J. Zucca
1988, Journal of Geophysical Research Solid Earth (93) 15016-15036
We determine compressional wave velocity and attenuation structures for the upper crust beneath Medicine Lake volcano in northeast California using a high-resolution active source seismic tomography method. Medicine Lake volcano is a basalt through rhyolite shield volcano of the Cascade Range, lying east of the range axis. The Pg wave from eight...

1988, Bulletin 1713-B
At the request of the U.S. Bureau of Land Management, approximately 105,200 acres of the Turtle Mountains Wilderness Study Area (CDCA-307) were evaluated for mineral resources (known) and resource potential (undiscovered).

T. E. C. Keith
1988, Journal of Geophysical Research Solid Earth (93) 6068-6076
Core hole VC-1 penetrated the southwestern ring fracture zone of the 1.1 Ma Valles caldera and at a depth of 333 m intersected the top of the Paleozoic section including the Abo Formation, Madera Limestone, and Sandia Formation, reaching a total depth of 856 m. The Paleozoic rocks, which consist...
Molecular composition and mobility of torbanite precursors: Implications for the structure of coal
M. A. Wilson, B.D. Batts, Patrick G. Hatcher
1988, Energy & Fuels (2) 668-672
Coorongite, a torbanite precursor found in South Australia, and algal residues derived from Botryococcus braunii and other algae have been examined by solid-state 13C NMR techniques. The majority of carbon in these materials is present as (CH2)n. However, variable-temperature studies show that a considerable proportion of the alkyl chains have...
Sorption characteristics of organic compounds on hexadecyltrimethylammonium-smectite
Stephen A. Boyd, Max M. Mortland, Cary T. Chiou
1988, Soil Science Society of America Journal (52) 652-657
When hexadedyltrimethylammonium (HDTMA) ion is exchanged for metal cations like calcium in smectite, the sorptive properties of the clay are greatly modified. The resultant HDTMA-smectite complex behaves as a dual sorbent, in the sorption of organic compounds, in which the mineral fraction functions as a solid adsorbent and the organic...
