Comparative risk assessment of the first-generation anticoagulant rodenticide diphacinone to raptors Comparative risk assessment of the first-generation anticoagulant rodenticide diphacinone to raptors
New regulatory restrictions have been placed on the use of some second-generation anticoagulant rodenticides in the United States, and in some situations this action may be offset by expanded use of first-generation compounds. We have recently conducted several studies with captive adult American kestrels and eastern screech-owls examining the toxicity of diphacinone (DPN) using both...

Using micro-seismicity and seismic velocities to map subsurface geologic and hydrologic structure within the Coso geothermal field, California Using micro-seismicity and seismic velocities to map subsurface geologic and hydrologic structure within the Coso geothermal field, California
Geothermal reservoirs derive their capacity for fluid and heat transport in large part from faults and fractures. Micro-seismicity generated on such faults and fractures can be used to map larger fault structures as well as secondary fractures that add access to hot rock, fluid storage and recharge capacity necessary to have a sustainable geothermal resource. Additionally, inversion of...

Emergent wetlands status and trends in the northern Gulf of Mexico: 1950-2010 Emergent wetlands status and trends in the northern Gulf of Mexico: 1950-2010
Poster presented during the Mississippi-Alabama Sea Grant Consortium Bays and Bayous Symposium 2012 on the decline of emergent wetlands in the northern Gulf of Mexico. Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide many resources, including plant and wildlife habitat, commercial and recreational economic...
Impact assessment of extreme storm events using a Bayesian network Impact assessment of extreme storm events using a Bayesian network
This paper describes an investigation on the usefulness of Bayesian Networks in the safety assessment of dune coasts. A network has been created that predicts the erosion volume based on hydraulic boundary conditions and a number of cross-shore profile indicators. Field measurement data along a large part of the Dutch coast has been used to train the network. Corresponding storm impact...

Post-earthquake building safety assessments for the Canterbury Earthquakes Post-earthquake building safety assessments for the Canterbury Earthquakes
This paper explores the post-earthquake building assessment program that was utilized in Christchurch, New Zealand following the Canterbury Sequence of earthquakes beginning with the Magnitude (Mw.) 7.1 Darfield event in September 2010. The aftershocks or triggered events, two of which exceeded Mw 6.0, continued with events in February and June 2011 causing the greatest amount of damage...

2014 Update of the United States National Seismic Hazard Maps 2014 Update of the United States National Seismic Hazard Maps
The U.S. National Seismic Hazard Maps are revised every six years, corresponding with the update cycle of the International Building Code. These maps cover the conterminous U.S. and will be updated in 2014 using the best-available science that is obtained from colleagues at regional and topical workshops, which are convened in 2012-2013. Maps for Alaska and Hawaii will be updated shortly...

Ambient response of a unique performance-based design building with dynamic response modification features Ambient response of a unique performance-based design building with dynamic response modification features
A 64-story, performance-based design building with reinforced concrete core shear-walls and unique dynamic response modification features (tuned liquid sloshing dampers and buckling-restrained braces) has been instrumented with a monitoring array of 72 channels of accelerometers. Ambient vibration data recorded are analyzed to identify modes and associated frequencies and damping. The...

Burn severity mapping in Australia 2009 Burn severity mapping in Australia 2009
In 2009, the Victoria Department of Sustainability and Environment estimated approximately 430,000 hectares of Victoria Australia were burned by numerous bushfires. Burned Area Emergency Response (BAER) teams from the United States were deployed to Victoria to assist local fire managers. The U.S. Geological Survey Earth Resources Observation and Science Center (USGS/EROS) and U.S. Forest...
