Earthquake warning system for Japan Railways’ bullet train; implications for disaster prevention in California
Y. Nakamura, B. E. Tucker
1988, Earthquakes & Volcanoes (USGS) (20) 140-155
In Japan, the level of public awareness of the dangers of earthquakes is high. The 1923 Kanto earthquake killed about 120,000 people out of a total Japanese population of about 50 million; an equivalent disaster in the U.S would involve 600,000 deaths. Today, Japanese society is well aware of the prediction...
Search for volatiles on icy satellites: I. Europa
R. H. Brown, D. P. Cruikshank, A. T. Tokunaga, R. G. Smith, Roger N. Clark
1988, Icarus (74) 262-271
New reflectance spectra have been obtained for both the leading and trailing sides of Europa, using the Cooled Grating Array Spectrometer (CGAS) of the NASA Infrared Telescope Facility (IRTF). The spectra are of higher precision than any yet obtained. Spectra of Europa's trailing side (central meridian longitude ≈300°) obtained in...
The fir trees have moved
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,...
Seabeam and seismic reflection imaging of the tectonic regime of the Andean continental margin off Peru (4°S to 10°S)
J. Bourgois, G. Pautot, W. Bandy, T. Boinet, P. Chotin, P. Huchon, B. Mercier de Lepinay, F. Monge, J. Monlau, B. Pelletier, M. Sosson, Roland E. von Huene
1988, Earth and Planetary Science Letters (87) 111-126
Marine geophysical surveys employing Seabeam, multi- and single-channel seismic reflection, gravity and magnetic instruments were conducted at two locations along the continental slope of the Peru Trench during the Seaperc cruise of the R/V “Jean Charcot” in July 1986. These areas are centered around 5°30′S and 9°30′S off the...
Extracting topographic structure from digital elevation data for geographic information-system analysis
Susan K. Jenson, Julia O. Domingue
1988, Photogrammetric Engineering and Remote Sensing (54) 1593-1600
Software tools have been developed at the U.S. Geological Survey's EROS Data Center to extract topographic structure and to delineate watersheds and overland flow paths from digital elevation models. The tools are specialpurpose FORTRAN programs interfaced with general-purpose raster and vector spatial analysis and relational data base management packages. The first...
Maps for America: cartographic products of the U.S. Geological Survey and others
Morris M. Thompson
1988, Report
"Maps for America" was originally published in 1979 as a Centennial Volume commemorating the Geological Survey's hundred years of service (1879 - 1979) in the earth sciences. It was an eminently fitting Centennial Year publication, for, since its establishment, the Geological Survey has continuously carried on an extensive program of...
Strontium-isotope stratigraphy of Enewetak Atoll
K.R. Ludwig, Robert B. Halley, Kathleen R. Simmons, Zell E. Peterman
1988, Geology (16) 173-177
87Sr/86Sr ratios determined for samples from a 350 m core of Neogene lagoonal, shallow-water limestones from Enewetak Atoll display a remarkably informative trend. Like the recently published data for Deep Sea Drilling Project (DSDP) carbonates, 87Sr/86Sr at Enewetak increases monotonically but not smoothly from...
Relation of pH and other soil variables to concentrations of Pb, Cu, Zn, Cd, and Se in earthworms
W. Nelson Beyer, Gary L. Hensler, Jeff Moore
1987, Pedobiologia (30) 167-172
Various soil treatments (clay, composted peat, superphosphate, sulfur, calcium carbonate, calcium chloride, zinc chloride, selenous acid) were added to experimental field plots to test the effect of different soil variables on the concentrations of 5 elements in earthworms (Pb, Cu, Zn, Cd. SE). Concentrations of the 5 elements were related...
Bibliography of U.S. Geological Survey water-resources reports for Utah
1987, Utah Division of Water Rights Information Bulletin 28
This bibliography contains a complete listing to December 31, 1986, of reports relating to the water resources of Utah prepared by personnel of the U.S. Geological Survey. Discussions of the related subjects of geology, hydrology, and chemical quality of the water are included in many of the reports. The reports...
Base of moderately saline ground water in the Uinta Basin, Utah, with an introductory section describing the methods used in determining its position
Lewis Howells, M.S. Longson, Gilbert L. Hunt
1987, Technical Publication 92
The base of the moderately saline water (water that contains from 3,000 to 10,000 milligrams per liter of dissolved solids) was mapped by using available water-quality data and by determining formation-water resistivities from geophysical well logs based on the resistivity-porosity, spontaneous potential, and resistivity-ratio methods. The contour map developed from...
Morgan Hill, California Earthquake, April 1984
Henry Spall, editor(s)
1987, Earthquake Information Bulletin (USGS) (17) 173-176
The Morgan Hill earthquake, a moderate-size (Mg=6.1, ML =6.2, M=6.2) event, was felt throughout central California on April 24, 1984. The epicenter of the earthquake was located near Halls Valley southwest of Mount Hamilton, and the event is presumed to have occurred on the Calaveras fault. Damage, however, was...
