An Account of Preliminary Landslide Damage and Losses Resulting from the February 28, 2001, Nisqually, Washington, Earthquake
Lynn M. Highland
2003, Open-File Report 2003-211
The February 28, 2001, Nisqually, Washington, earthquake (Mw = 6.8) damaged an area of the northwestern United States that previously experienced two major historical earthquakes, in 1949 and in 1965. Preliminary estimates of direct monetary losses from damage due to earthquake-induced landslides is approximately $34.3 million. However, this figure does...
Earthquakes of the Central United States, 1795-2002
Russell L. Wheeler
2003, Open-File Report 2003-232
This report describes construction of a list of Central U.S. earthquakes to be shown on a large-format map that is targeted for a non-technical audience. The map shows the locations and sizes of historical earthquakes of magnitude 3.0 or larger over the most seismically active part of the central U.S.,...
Digital depth horizon compilations of the Alaskan North Slope and adjacent Arctic regions
Richard W. Saltus, Kenneth J. Bird
2003, Open-File Report 2003-230
Data have been digitized and combined to create four detailed depth horizon grids spanning the Alaskan North Slope and adjacent offshore areas. These map horizon compilations were created to aid in petroleum system modeling and related studies. Topography/bathymetry is extracted from a recent Arctic compilation of global onshore DEM and...

2003, Open-File Report 2003-204
The metallogenic belts and locations of major mineral deposits of Northeast Asia are portrayed on Sheets 1-4. Sheet 1 portrays the location of significant lode deposits and placer districts at a scale of 1:7,500,000. Sheets 2-4 portray the metallogenic belts of the region in a series of 12 time-slices from...
Preliminary publications book 2 from project on mineral resources, metallogenesis, and tectonics of northeast Asia
Warren J. Nokleberg, Robert J. Miller, Vera V. Naumova, Alexander I. Khanchuk, Leonid M. Parfenov, Mikhail I. Kuzmin, Tatiana M. Bounaeva, Alexander A. Obolenskiy, Sergey M. Rodionov, Zhan V. Seminskiy, Michael F. Diggles
2003, Open-File Report 2003-203
This is the Web version of a CD-ROM publication. This report consists of summary major compilations and syntheses accomplished in the six-year project through April 2003 for the study on the Mineral Resources, Metallogenesis, and Tectonics of Northeast Asia (Eastern and Southern Siberia, Mongolia, Northeastern China, South Korea, and Japan)....
Cruise summary for P-1-02-SC: acoustic imaging of natural oil and gas seeps and measurement of dissolved methane concentration in coastal waters near Pt. Conception, California
T.D. Lorenson, Jennifer A. Dougherty, William Ussler III, Charles K. Paull
2003, Open-File Report 2003-122
Water-column acoustic anomalies and methane concentrations were documented in coastal waters surrounding Pt. Conception, California, in March 2002. The purpose of this survey, supported by the Minerals Management Service, was to locate active oil and gas seeps in the area as a background for further studies to determine hydrocarbon flux,...
Assessment of habitat and streamflow requirements for habitat protection, Usquepaug–Queen River, Rhode Island, 1999–2000
David S. Armstrong, Gene W. Parker
2003, Open-File Report 2002-438
The relations among stream habitat and hydrologic conditions were investigated in the Usquepaug–Queen River Basin in southern Rhode Island. Habitats were assessed at 13 sites on the mainstem and tributaries from July 1999 to September 2000. Channel types are predominantly low-gradient glides, pools, and runs that have a sand and...
Methods of analysis by the U.S. Geological Survey Organic Geochemistry Research Group: Determination of acetamide herbicides and their degradation products in water using online solid-phase extraction and liquid chromatography/mass spectrometry
E.A. Lee, A.P. Strahan
2003, Open-File Report 2003-173
An analytical method for the determination of 6 acetamide herbicides (acetochlor, alachlor, dimethenamid, flufenacet, metolachlor, and propachlor) and 16 of their degradation products in natural water samples using solid-phase extraction and liquid chromatography/mass spectrometry is described in this report. Special consideration was given during the development of the method to...

The map is the result of a detailed compilation and synthesis at 5 million scale and is part of a major international collaborative study...
A compendium of P- and S-wave velocities from surface-to-borehole logging; summary and reanalysis of previously published data and analysis of unpublished data
David M. Boore
2003, Open-File Report 2003-191
For over 28 years, the U.S. Geological Survey (USGS) has been acquiring seismic velocity and geologic data at a number of locations in California, many of which were chosen because strong ground motions from earthquakes were recorded at the sites. The method for all measurements involves picking first arrivals of...
Java Programs for Using Newmark's Method and Simplified Decoupled Analysis to Model Slope Performance During Earthquakes
Randall W. Jibson, Matthew W. Jibson
2003, Open-File Report 2003-5
Landslides typically cause a large proportion of earthquake damage, and the ability to predict slope performance during earthquakes is important for many types of seismic-hazard analysis and for the design of engineered slopes. Newmark's method for modeling a landslide as a rigid-plastic block sliding on an inclined plane provides a...
