Landslide Hazards
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 071-00
Landslide hazards occur in many places around What Can You Do If You Live Near Steep Hills? the world and include fast-moving debris flows, slow-moving landslides, and a variety of flows and slides initiating from volcanoes. Each year, these hazards cost billions of dollars and cause numerous fatalities and injuries....
Peligros de deslizamientos [Landslide Hazards]
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 072-00
Deslizamientos, flujos de escombrera y desastres geológicos similares provenientes de volcanes ocurren alrededor del mundo. Cada año estos desastres causan billones de dólares en pérdidas y un sinnúmero de fatalidades y heridos. El primer paso para reducir los efectos dañinos causados por estos desastres es el conocimiento y educación acerca...
Map showing inventory and regional susceptibility for Holocene debris flows, and related fast-moving landslides in the conterminous United States
Earl E. Brabb, Joseph P. Colgan, Timothy C. Best
2000, Miscellaneous Field Studies Map 2329
Introduction Debris flows, debris avalanches, mud flows and lahars are fast-moving landslides that occur in a wide variety of environments throughout the world. They are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and often strike without warning. This map represents a significant effort...

Organic geochemistry data of Alaska
Charles N. complied by Threlkeld, Raymond C. Obuch, G.L. Gunther
2000, Data Series 59
In order to archive the results of various petroleum geochemical analyses of the Alaska resource assessment, the USGS developed an Alaskan Organic Geochemical Data Base (AOGDB) in 1978 to house the data generated from USGS and subcontracted laboratories. Prior to the AOGDB, the accumulated data resided in a flat data...
First-principles calibration of 38Ar tracers :implications for the ages of 40Ar/39Ar fluence monitors
Marvin A. Lanphere, G. Brent Dalrymple
2000, Professional Paper 1621
We describe the analytical procedure for first-principles calibrations of 38Ar tracers in the U.S. Geological Survey (USGS) Laboratory in Menlo Park, California. The ages of fluence monitors determined in the USGS laboratory and those reported in the literature differ by nearly 2 percent. However, the radiogenic-40Ar content of the primary...
Estimated water withdrawals and use in Pennsylvania, 1995
Russell A. Ludlow, William A. Gast
2000, Fact Sheet 174-99
In practical terms, water use is divided into two basic types: instream use and offstream use. Instream use is water used in its natural channel, basin, or behind a dam and includes activities such as fishing, boating, and other recreational activities. Instream use also includes hydroelectric power generation. Off-stream use...
Digital geologic map of the Butler Peak 7.5' quadrangle, San Bernardino County, California
Fred K. Miller, Jonathan C. Matti, Howard J. Brown, Digital preparation by P. M. Cossette
2000, Open-File Report 2000-145
Open-File Report 00-145, is a digital geologic map database of the Butler Peak 7.5' quadrangle that includes (1) ARC/INFO (Environmental Systems Research Institute) version 7.2.1 Patch 1 coverages, and associated tables, (2) a Portable Document Format (.pdf) file of the Description of Map Units, Correlation of Map Units...
Organic metamorphism in the California petroleum basins; Chapter B, Insights from extractable bitumen and saturated hydrocarbons
Leigh C. Price
2000, Bulletin 2174-B
Seventy-five shales from the Los Angeles, Ventura, and Southern San Joaquin Valley Basins were extracted and analyzed. Samples were chosen on the basis of ROCK-EVAL analyses of a much larger sample base. The samples ranged in burial temperatures from 40 ? to 220 ? C, and contained hydrogen-poor to hydrogen-rich organic matter (OM), based on OM visual typing and a...

Puerto Rico: Marine sediments, terrestrial and seafloor imagery, and tectonic interpretations
Kathryn M. Scanlon, Peter R. Briere
2000, Open-File Report 2000-6
Introduction: Puerto Rico is an island situated in the plate boundary zone between the Caribbean and the North American Plates. This is a geologically fascinating, tectonically active region, where the Caribbean Plate has over-ridden the North American Plate and is now sliding past it with strike-slip motion. The details of...
Basin level statistical properties of topographic index for North America
Praveen Kumar, Kristine L. Verdin, Susan K. Greenlee
2000, Advances in Water Resources (23) 571-578
For land–atmosphere interaction studies several Topmodel based land-surface schemes have been proposed. For the implementation of such models over the continental (and global) scales, statistical properties of the topographic indices are derived using GTOPO30 (30-arc-second; 1 km resolution) DEM data for North America. River basins and drainage...
Laboratory performance in the Sediment Laboratory Quality-Assurance Project, 1996-98
John D. Gordon, Carla A. Newland, Shane T. Gagliardi
2000, Water-Resources Investigations Report 99-4184
This report describes the results of the first 3 years of an ongoing study of sediment laboratories used by the U.S. Geological Survey (USGS). The sediment laboratories currently in operation constitute the entire USGS national laboratory system for sediment analyses. As with all environmental data, physical sediment data can be...
The human factor in mining reclamation
Belinda F. Arbogast, Daniel H. Knepper, William H. Langer
2000, Circular 1191
Rapid urbanization of the landscape results in less space available for wildlife habitat, agriculture, and recreation. Mineral resources (especially nonmetallic construction materials) become unrecoverable due to inaccessibility caused by development. This report both describes mine sites with serious problems and draws attention to thoughtful reclamation projects for better future management....
Occurrence, distribution, and concentration of hydrocarbons in and near the Shell Valley Aquifer, North Dakota
Wayne R. Berkas
2000, Open-File Report 99-194
Water samples from 27 wells completed in and near the Shell Valley aquifer were analyzed for benzene, toluene, ethylbenzene, and xylene (BTEX), polynuclear aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), and pentachlorophenol (PCP) using the enzyme-linked immunoassay method. The analyses indicated the presence of PAH, PCB, and PCP in the study...
