Tousson R. Toppozada, D.M. Branum, M.S. Reichle, C.L. Hallstrom
2002, Bulletin of the Seismological Society of America (92) 2555-2601
The San Andreas fault zone has been a very significant source of major California earthquakes. From 1812 to 1906 it generated four major earthquakes of M ∼7 or larger in two pairs on two major portions of the fault. A pair of major earthquakes occurred on the central to southern region, where...
Timing of large earthquakes since A.D. 800 on the Mission Creek strand of the San Andreas fault zone at Thousand Palms Oasis, near Palm Springs, California
T. E. Fumal, M. J. Rymer, G. G. Seitz
2002, Bulletin of the Seismological Society of America (92) 2841-2860
Paleoseismic investigations across the Mission Creek strand of the San Andreas fault at Thousand Palms Oasis indicate that four and probably five surface-rupturing earthquakes occurred during the past 1200 years. Calendar age estimates for these earthquakes are based on a chronological model that incorporates radiocarbon dates from 18 in situ burn layers...
Concordant paleolatitudes for Neoproterozoic ophiolitic rocks of the Trinity Complex, Klamath Mountains, California
E. A. Mankinen, N. Lindsley-Griffin, J. R. Griffin
2002, Journal of Geophysical Research B: Solid Earth (107) EPM 11-1-EPM 11-18
New paleomagnetic results from the eastern Klamath Mountains of northern California show that Neoproterozoic rocks of the Trinity ophiolitic complex and overlying Middle Devonian volcanic rocks are latitudinally concordant with cratonal North America. Combining paleomagnetic data with regional geologic and faunal evidence suggests that the Trinity Complex and related terranes...
Distribution and significance of small, artificial water bodies across the United States landscape
S. V. Smith, W. H. Renwick, J.D. Bartley, R. W. Buddemeier
2002, Science of the Total Environment (299) 21-36
At least 2.6 million small, artificial water bodies dot the landscape of the conterminous United States; most are in the eastern half of the country. These features account for approximately 20% of the standing water area across the United States, and their impact on hydrology, sedimentology, geochemistry, and ecology is...

S. E. Hough, S. Martin
2002, Bulletin of the Seismological Society of America (92) 3259-3268
The three principal New Madrid mainshocks of 1811-1812 were followed by extensive aftershock sequences that included numerous felt events. Although no instrumental data are available for either the mainshocks or the aftershocks, available historical accounts do provide information that can be used to estimate magnitudes and locations for the large...

2002, SIDA, Contributions to Botany (20) 691-765
We surveyed the flora of Oktibbeha County, Mississippi, U.S.A., from February 1994 to 1996. Occupying 118 square kilometers in east-central Mississippi, Oktibbeha County lies among 3 physiographic regions that include, from west to east, Interior Flatwoods, Pontotoc Ridge, and Black Prairie. Accordingly, the county harbors a diverse flora. Based on...
Coalbed gas play emerges in eastern Kansas basins
K.D. Newell, L. L. Brady, J.P. Lange, T.R. Carr
2002, Oil & Gas Journal (100) 36-41
Coalbed gas from Middle Pennsylvanian rocks in eastern Kansas is an emerging new energy play. Many of the critical geological parameters that will prove to be the major controls on the production fairways of this potential new resource have yet to be determined. Nevertheless, preliminary analyses indicate that recent leasing...
Re-analysis of a banding study to test the effects of an experimental increase in bag limits of mourning doves
David L. Otis, Gary C. White
2002, Journal of Applied Statistics (29) 479-495
In 1966-1971, eastern US states with hunting seasons on mourning doves (Zenaida macroura) participated in a study designed to estimate the effects of bag limit increases on population survival rates. More than 400 000 adult and juvenile birds were banded and released during this period, and subsequent harvest and return...

Mark W. Miller, E. M. Greenstone, W. Greenstone, Keith L. Bildstein
2002, The Wilson Bulletin (114) 479-484
The Broad-winged Hawk (Buteo platypterus) breeds in eastern and central Canada and the United States, and winters in Central America and northern and central South America. Birders and ornithologists count migrating Broad-winged Hawks at dozens of traditional watch sites throughout the northeastern United States. We modeled counts of migrating...
The December 1872 Washington state earthquake
W. H. Bakun, R. A. Haugerud, M. G. Hopper, R.S. Ludwin
2002, Bulletin of the Seismological Society of America (92) 3239-3258
The largest historical earthquake in eastern Washington occurred on 15 December 1872. We used Modified Mercalli intensity (MMI) assignments for 12 twentieth-century earthquakes to determine attenuation relations for different regions in the Pacific Northwest. MMI attenuation for propagation paths east and west of the Cascade Mountains differs significantly only for...

2002, Geological Society of America Bulletin (114) 169-177
A high-resolution aeromagnetic survey of the Puget Lowland shows details of the Seattle fault zone, an active but largely concealed east-trending zone of reverse faulting at the southern margin of the Seattle basin. Three elongate, east-trending magnetic anomalies are associated with north-dipping Tertiary strata exposed in the hanging wall; the...

2002, Journal of Geophysical Research B: Solid Earth (107) ESE 22-1-ESE 22-23
The availability of regional earthquake data from the Pacific Northwest Seismograph Network (PNSN), together with active source data from the Seismic Hazards Investigation in Puget Sound (SHIPS) seismic experiments, has allowed us to construct a new high-resolution 3-D, P wave velocity model of the crust to a depth of about...
Spatial variability in water-balance model performance in the conterminous United States
Lauren E. Hay, Gregory J. McCabe
2002, Journal of the American Water Resources Association (38) 847-860
A monthly water-balance (WB) model was tested in 44 river basins from diverse physiographic and climatic regions across the conterminous United States (U.S.). The WB model includes the concepts of climatic water supply and climatic water demand, seasonality in climatic water supply and demand, and soil-moisture storage. Exhaustive search techniques...
Effects of forest fragmentation on brood parasitism and nest predation in eastern and western landscapes
J.F. Cavitt, T. E. Martin
2002, Conference Paper, Studies in Avian Biology
The fragmentation of North American forests by agriculture and other human activities may negatively impact the demographic processes of birds through increases in nest predation and brood parasitism. In fact, the effects of fragmentation on demographic processes are thought to be a major underlying cause of long-term population declines of...

Daniel Dzurisin, Michael P. Poland, Roland Burgmann
2002, Journal of Geophysical Research B: Solid Earth (107) ECV 8-1-ECV 8-16
Leveling surveys of a 193‐km circuit across Medicine Lake volcano (MLV) in 1954 and 1989 show that the summit area subsided by as much as 302 ± 30 mm (−8.6 ± 0.9 mm/yr) with respect to a datum point near Bartle, California, 40 km to the southwest. This result corrects...
Some aspects of resource uncertainty and their economic consequences in assessment of the 1002 Area of the Arctic National Wildlife Refuge
Emil D. Attanasi, John H. Schuenemeyer
2002, Natural Resources Research (11) 109-120
Exploration ventures in frontier areas have high risks. Before committing to them, firms prepare regional resource assessments to evaluate the potential payoffs. With no historical basis for directly estimating size distribution of undiscovered accumulations, reservoir attribute probability distributions can be assessed subjectively and used to project...

2002, Mineralium Deposita (37) 38-60
Alkaline-related epithermal vein, breccia, disseminated, skarn, and porphyry gold deposits form a belt in the southern Rocky Mountains along the eastern edge of the North American Cordillera. Alkaline igneous rocks and associated hydrothermal deposits formed at two times. The first was during the Laramide orogeny (about 70–40 Ma), with deposits restricted...
