2009, Tectonophysics (475) 423-437
We present active-source seismic data recorded along a 300 km-long profile across the Three Gorges area of the western Yangtze platform, central China. From west to east, the profile crosses the Zigui basin, Huangling dome and Jianghan basin. The derived crustal P-wave velocity structure changes...
Is there a basis for preferring characteristic earthquakes over a Gutenberg–Richter distribution in probabilistic earthquake forecasting?
Thomas E. Parsons, Eric L. Geist
2009, Bulletin of the Seismological Society of America (99) 2012-2019
The idea that faults rupture in repeated, characteristic earthquakes is central to most probabilistic earthquake forecasts. The concept is elegant in its simplicity, and if the same event has repeated itself multiple times in the past, we might anticipate the next. In practice however, assembling a fault-segmented characteristic earthquake rupture...

Biofuels, water resources and climate change: Solving the sustainability puzzle
Ralph Holzfaster, Duane Kristensen, Todd Sneller, Larry L. Tieszen, Kenneth Cassman
2009, Conference Paper, Proceedings from the 2008 climate change workshop
Nebraska is now the second-largest producer of corn ethanol in the U.S. This is largely because of the state’s comparative advantages. For one, the state’s water resources enable a huge capacity for irrigation – Nebraska ranks second in irrigated crop acres, behind California. Nebraska is the third-largest corn producer in...

Evaluation of Ground-Motion Modeling Techniques for Use in Global ShakeMap - A Critique of Instrumental Ground-Motion Prediction Equations, Peak Ground Motion to Macroseismic Intensity Conversions, and Macroseismic Intensity Predictions in Different Tectonic Settings
Trevor I. Allen, David J. Wald
2009, Open-File Report 2009-1047
Regional differences in ground-motion attenuation have long been thought to add uncertainty in the prediction of ground motion. However, a growing body of evidence suggests that regional differences in ground-motion attenuation may not be as significant as previously thought and that the key differences between regions may be a consequence...

Aspects and implications of bear reintroduction: Chapter 6
Joseph D. Clark
Matt W. Hayward, Michael J. Somers, editor(s)
2009, Book chapter, Reintroduction of top-order predators
Bear reintroduction has been practiced worldwide with varying degrees of success. Homing is a significant issue for American black bears, Ursus americanus, and winter-release techniques of females with cubs have been successfully used to improve settling rates and survival. Reintroduction success for all bear species appears to be positively correlated...
