All or part of 25 7.5-minute quadrangles identifying 8465 landslides - largely slow-moving slides and earth flows - in Alameda County, California, have been converted to a digital-map database, compiled at 1:24,000 scale and plotted at 1:62,500 scale, that can be acquired from the U.S. Geological Survey over the Internet...
Map scales
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 038-00
To be most useful, a map must show locations and distances accurately on a sheet of paper of convenient size. This means that all things included in the map-ground area, rivers, lakes, roads, distances between features, and so on must be shown proportionately smaller than they really are. The proportion chosen for a particular map is its scale....
A reconnaissance study of the effect of irrigated agriculture on water quality in the Ogallala Formation, Central High Plains Aquifer
Peter B. McMahon
2000, Fact Sheet 009-00
In 1998, the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program began a regional study of water quality in the High Plains aquifer. The High Plains aquifer underlies an area of about 174,000 square miles in parts of eight States. Because of its large size, the High Plains aquifer has...

2000, Seismological Research Letters (71) 338-343
A major earthquake occurred near the town of Chi-Chi in Nantou County, Taiwan, at 1:47 am (local time), 21 September 1999, about 150 km south of Taipei. This is the largest earthquake to have occurred on land in Taiwan during the 20th century. Although Taiwan has an earthquake building...
Recent tectonics of the Blanco Ridge, eastern blanco transform fault zone
Robert Dziak, C.G. Fox, R. Embley, J.L. Nabelek, Jochen Braunmiller, Randolph A. Koski
2000, Marine Geophysical Research (21) 423-450
Bathymetric, hydro-acoustic, seismic, submersible, and gravity data are used to investigate the active tectonics of the eastern Blanco Transform Fault Zone (BTFZ). The eastern BTFZ is dominated by the ∼150 km long transform-parallel Blanco Ridge (BR) which is a right-lateral strike-slip fault bordered to the east and west by the Gorda...
Nanogram quantities of a DNA vaccine protect rainbow trout fry against heterologous strains of infectious hematopoietic necrosis virus
S. Corbeil, S. E. LaPatra, Eric Anderson, G. Kurath
2000, Vaccine (18) 2817-2824
The efficacy of a DNA vaccine containing the glycoprotein gene of infectious hematopoietic necrosis virus (IHNV), a rhabdovirus affecting trout and salmon, was investigated. The minimal dose of vaccine required, the protection against heterologous strains, and the titers of neutralizing antibodies produced were used to evaluate the potential of the...

2000, Advances in Space Research (26) 1641-1647
We present a brief synopsis of the nature of SSI data that was taken during the nominal Galileo mission. Significant results are briefly described. These include evidence for geologic activity on Europa that supports the hypothesis of liquid water under a thin ice shell; a demonstration of the ubiquitous presence...
Nutrients discharged to the Mississippi River from eastern Iowa watersheds, 1996-1997
Kent Becher, Douglas J. Schnoebelen, Kimberlee K. Akers
2000, Journal of the American Water Resources Association (36) 161-173
The introduction of nutrients from chemical fertilizer, animal manure, wastewater, and atmospheric deposition to the eastern Iowa environment creates a large potential for nutrient transport in watersheds. Agriculture constitutes 93 percent of all land use in eastern Iowa. As part of the U.S. Geological Survey National Water Quality Assessment Program,...

A topographic map tells you where things are and how to get to them, whether you're hiking, biking, hunting, fishing, or just interested in the world around you. These maps describe the shape of the land. They define and locate natural and manmade features like woodlands, waterways, important buildings, and bridges. They show the distance between any two places,...
